Optic of the Week: Leupold CQ/T

First time I used a Leupold CQ/T it was mounted on a friends M1A.  It seemed to me an impractical combination as it was mounted really high making it awkward on the M1A and I’d much rather have more magnification on a .30 cal.  That aside, I found the CQ/T rather interesting.

The Leupold Close Quarters/ Tactical is a real odd duck of a scope that really came out before its time.  Before the 1-X variable power craze of nowadays, there was the 1-3x CQ/T.  It is fast and easy to switch between 1x and 3x because the entire ocular section of the scope (up to the rail) rotates.  The Leupold CQBSS received rave reviews for this feature, but it was in the CQ/T long before it.

Most of the CQ/T scopes have a circle dot reticle (much like the Eotech) that can be illuminated in amber or red.  The circle dot is always visible.  Before it was discontinued Leupold did finally make some with their CMR reticle, an ACOG like bullet drop chart(BDC).

Reticle is 2nd focal plane.  It is eteched At 1x the Dot is 3 MOA and the circle is 18 inches at 25 yards (~69 MOA), at 3x the Dot is 9 MOA and the circle is 6 feet at 200 yards (~34 MOA).  The math is much simpler if you round to 72 and 36 MOA which I think was the intent.

Illuminated reticle is bright, but still somewhat lacking outdoors.  The adjustment has 12 positions including OFF and night vision modes.  The reticle will blink if you have a low battery.  I couldn’t get a good picture outdoors of the illuminated reticle so here is an indoor one.

Adjustments are a simple 1/2 covered turrets.

The “battery pack” is easily removed or secured with less than a quarter turn.  

Weirdly, you have a removable container to put the battery in.  If you had several you could do quick battery changes, and this also would protect the optic should the battery leak.  It doesn’t slow down battery changes, but makes the process different from other optics.

The mount is rather weird.  The CQ/T has a narrow section so that it can mount to an AR15 carry handle.  Unlike other scopes that can do that, this one has 3 threaded holes to give different eye relief options.

The rail mount is two piece and pinches the scope to your rail.  Solidly mounts the scope but makes it annoying when you are taking it off or moving it.

I am really impressed by the CQ/T and I think it is a good scope, but it is just shy of a great scope.  Leupold seemed to make some odd design decisions regarding it.  For example the rails on the scope, they should have either gotten rid of them, or gotten serious with low profile adjustment so that there would be a usable amount of rails.  The circle is huge, I think they would have been better off with a 1 MOA dot and a 19-20 MOA circle.  A mount that doesn’t get all loose and floppy when you are removing or attaching it would also have been an improvement.  The battery pack was an interesting idea but could be replaced with a simpler cap.  I think the biggest possible improvement would have been an illuminated horseshoe reticle with an ACOG like BDC.

I went and read some old reviews of this scope and the complaints were generally about cost, weight, size, and eye relief.  I think this came out in a time when people were not used to spending a good bit of money on an rifle optic.  Now people gladly spend large sums for AR optics.  This scope is 17.5 oz, so it is heavy, about twice the weight of an ACOG.  But to put it in perspective it is a 1/3 pound lighter than the similar Elcan Specter DR.  To me it doesn’t feel overly large or heavy on an AR.  Eye relief seemed fine to me, but unlike a reflex sight, you still have strict limits on where you can place your head to use it.

I put this scope on my 5.45 AR (pictured in the first picture) and did a little bit of rapid fire and shot some clay pigeons at 50 yards.  I found the CQ/T to be very fast and easy to use.  I like it, but I feel it is just shy of being a great optic.  I would not recommend it because it has discontinued, not to mention there are now 1-6x scopes that are similar size, weight, and MSRP.  I think that is a shame because I think with just a little work it could have been exceptional.  Lastly, there are some being sold really cheap lately, if you want one, now might be the time to get one.

 

Optic of the week – SU-231/PEQ Eotech 553

Around a decade ago it was common knowledge that Eotechs were faster to use and better than Aimpoints.  Just like how not very long before that it was common knowledge that the Earth was flat.

The Eotech sights use a laser to project a hologram of the reticle in the optical window.  This allows for a greater variety of reticle patterns then a diode sight like the Aimpoint.  Most common in Eotech sights are a 1 MOA dot with a 65 MOA circle around it.  A downside to holosights are shorter battery life.  Battery life on the Eotech is advertised to be about 1000 hours.

There are other variations with additional dots to function as a drop chart.  There are also machine gun reticles.

For the life of me, I could not get the reticle to show up nicely in a picture.  Despite how it looks in the photo, the reticle is bright and easy to see.  If you focus on the reticle, you will see that it is comprised of a bunch of dots, it will appear to be fuzzy if you have the brightness cranked up.  That is just due to the nature of how it works.

Windage and Elevation is easy to adjust using a coin or similar tool.  Both adjustments have positive clicks and are easily accessible on the right side of the sight.

Brightness is adjusted using the up and down arrow buttons on the rear of the sight (there are some models where the adjustments are on the left side of the sight).  If the sight is off, hitting one of these buttons will turn on the sight.

The Eotech will automatically turn it self off it preserve battery life.  Turning it on by hitting the down button will have the Eotech turn off after 4 hours.  Hitting the up button will have it off after 8 hours.  Holding both buttons will turn the Eotech off immediately.

Some models, like this 553 have a NV button that will dim the optic for night vision use.  While you can sorta get away with using most optics with night vision by using a dim setting, that can damage nightvision over time.  NV setting reduce the brightness enough so that you will not damage your expensive night vision device.

I did some shooting with this Eotech and with a Aimpoint T-1 on the same rifle.  Shooting from the bench, or rapidly engaging multi targets off hand was quick and easy with either optic.  Both were fast and easy to use, but I would not say the Eotech was any faster or easier than the Aimpoint.  The only real noticeable difference in use was that this Eotech 553 felt much heavier on the rifle than the T-1.  Looking at the stats on them, the Eotech is about 3 times heavier.  That is an additional half pound on the rifle over the weight of the T-1.

I used to be a major fan of Eotechs.  But over the years I saw multiple Eotech Holographic Weapon Sights fail in various ways.  Battery terminals would break, I’ve seen the prism break loose.  Lenses delaminate, and reticles dimming.  The biggest issue was that many Eotechs would drain their batteries even when off.  I found that my Eotech 512 would drain the batteries even when off.  I had to store it with the batteries removed.  I felt the high failure rate of Eotech sights was damning on its own.

Turns out it gets worse.  L3 was aware of issues with their like of Eotech sights, and were covering it up.  L3 paid a settlement of 25.6 million dollars over this.  The biggest issues they were covering up were that the sight wasn’t actually parallax free and that there could be massive zero changes if the optic was exposed to temperature changes and it turns out that Eotech sights also were not as waterproof as they are suppose to be.

Despite these persistent issues, you still see fans of Eotech sights defend them online.    The most often statement in Eotech’s defense is that the Navy SEALs are using Eotech sights.  I point out that the SEALs use what they are issued, are the individuals are not purchasing these out of pocket.  They also have far more range time and funding so doing stuff like rezeroing before a mission or replacing batteries each mission is a non issue.  But even NSWC Crane had to issue a Safety of Use Message about the Eotech warning about a 4 MOA Thermal Drift problem, fading and disappearing reticles, and 4-6 MOA parallax error.  SOCOM acknowledge these sights have issues.

So if you want a known substandard sight, buy Eotech.

Optic of the Week: C-More Tactical Reflex Sight

C-More ARW-4.  Black aluminum body, 4 MOA dot.

Around 2003ish I learned about the C-More Tactical Reflex sight which paired a C-More Reflex Sight along with a cut down adjustable rear sight carry handle base for the AR15.  I’ve wanted one since then.  Back in 2017 I learned they were discontinued, so I found a used one and purchased it.  I fully expected to have it for two weeks before deciding that I didn’t like it, just to turn around and sell it.  Instead I really love it.

The C-More sights never seemed to gain much ground in the tactical market as they were seen as fragile and unreliable.  Yet they were very common place, and still used a good bit on the competition side of things.

First thing of note with the C-More sight is that there are a huge number of variations of them.  The body can be plastic or aluminum.  It can be a rail mount, slide mount (for pistols) or a bridge mount (for pistols).  The sight can be purchased in different colors, Black, Grey, Red, Blue, and Green.  Also you can change the dot size by replacing a module giving you the choices of 2, 4, 6, 8, 12, or 16 MOA dots.  Then there are also differences in the battery compartment and, the intensity switch between models.

I think the C-More is popular in the competition market for several reasons.  Being able to choose a dot size that works best for you(E.G. larger dot for use on a pistol) is a major plus.  Some of the C-More models are rather inexpensive, down to about $240 list price right now.  Also being able to get them in a color that matches your competition gun doesn’t hurt.

Now I don’t know for sure why the C-More Reflex Sight never really caught on in the tactical community.  From what I’ve read it sounds like early on the Army and some individuals tried the polymer C-More and decided it was not durable enough for combat.  I believe this was also done back in a time before reflex sights had become mainstream for combat weapons, and they were still rather untrusted.  In any event, the C-More seemed to have found its home primarily in the competition environment.

For me, my C-More sight found a home on a Colt 6933 upper.

This C-More model gives me a standard rear sight.  If I wanted to I could remove the optic from this base and attach it to a rail mount base.

The Iron Sights provide a lower 1/3 co-witness.

Looking over the sights give an awesome sight picture with a crisp red dot in a thin circle.

Brightness is adjusted by a knob behind the emitter.  On this model the brightness knob has distinct clicks and the first couple of settings are for night vision.  On many C-More models this is just a click-less rheostat.

The battery compartment is in front of the emitter.  On this model there are 2 non-captive thumbscrews holding the top plate on.  Other C-More models use Allen screws.  I don’t think these screws would come loose on their own, but if they did they would be easy to lose.

Windage and Elevation adjustments each have a locking screw.  Neither adjustment has clicks, so you just turn the screw the amount you hope is right, lock it down, test fire, then adjust again.  While click less adjustments are sometimes heralded as superior due to the ability to make smaller adjustments than a set click value, but in reality it tends to just make the zeroing procedure guesswork.

When I came up with the idea of doing the optic of the week posts, I planned to do side my side speed and handling comparisons of the various optics.  For example, in years past it used to be considered common knowledge that the Eotech was “faster” than the Aimpoint.  I believed this for a while and that is why I started with Eotech.  Finally the multiple personal Eotech failures drove me to Aimpoint.  Now when I try these various optics side by side, I don’t notice a measurable speed difference, they all just work (with a few notable exceptions).

I really love this sight, but in the end I do not recommend it.  It has been discontinued, so that makes it hard to recommend in the first place.  Now days we have newer and smaller optics that have proven to be very durable and have much longer battery life(such as the Aimpoints) that render this old design obsolete.  The open design of the C-More allows the chance of dirt or debris to block the emitter.  In the past the light from the emitters of reflex sights were often considered a major deal breaker as it might compromise your location to the enemy.  Over time the massive force multiplier that optics function is considered to well offset the risk of your location being revealed to the enemy by the sight.  I find the C-More red emitter and glare from the lens is very visible from in front of the optic.  It seems more so than newer alternatives.  I tried to get some pictures of this but I was unable to get it to show up well.

I think the C-More is a really nice sight, but it has been eclipsed by newer, better options.

Optic of the Week: Trijicon RX01

This weeks optic of the week is the Trijicon RX01.  This particular model has the rail mount, they are also seen with a gooseneck mount for fixed carry handles.

I wouldn’t say that these old reflex sights are bad, but I do not recommend getting one.  I was under the impression they were discontinued and out of production, but I see that there are plenty new ones for sale for about $430ish.

I owned a RX01 back in 2005ish.  The main reason I bought it back then was that it did not use batteries, and most battery operated sights of the time use odd sized batteries and had poor battery life.  I had used it on M16A2s, M249s, and my personal rifle.  I later replaced it with an Eotech 512.

The RX01 Reflex Sight uses Tritium and fiber optic to illuminate the reticle.  There are two major downsides to this sight.  First is that the radioactive Tritium has a half life and the Tritium is not replaceable and dims over time.  Second is that due to the nature of how the sight works, there are many times when it can wash out.  Most noticeably is if you are in a dark room looking out into a bright area, the dim reticle will not be very visible.  My having that issue is why I ended up selling the RX01 I owned.

When I received this RX01, I took it out with a target at 25 yards for zeroing.

I don’t know why the camera didn’t pick up the amber reticle well, but it was very visible to my eye.

Windage and Elevation can be adjusted using a coin/screwdriver or Allen wrench.  The adjustments are very positive clicks that are suppose to be 1 MOA.  When I zeroed this sight I found the adjustment seemed to be closer to 3/4 MOA per click.  The housing is loose on this sight, and I don’t recall it being loose on the one I owned all those years ago.  I wonder if there is any sort of mechanical damage or issues with this particular sight.

I shot very poorly with this site when zeroing it.  I shot the same rifle with a difference sight that day and did much better so I rather like to blame this optic.  As I said previously, I wonder if this particular one is damaged.  I am tempted to contact Trijicon and see about sending it in for inspection.  Pictures of the zeroing target omitted to protect the embarrassed party.

After obtaining a zero I tried some rapid fire on clay pigeons on the berm at 25 yards.  In the sunlight the reticle was bright and crisp.  The reticle was easy to follow during recoil.  I would say that shooting the pigeons was easy, but the blue tint of the lens made the orange clay pigeons invisible against the dark dirt berm.  I had to use the Bindon Aiming Concept where I spotted the clays with my left eye and overlayed the reticle with my right.

*Mental note:  If the enemy is using a Trijicon Reflex wear orange.”

I tried using the RX01 with an Aimpoint 3X magnifier and they worked together excellently.

I found shooting with the RX01 in daylight very fun, easy, and it performed awesomely.  But I know that I have had issues with the reticle washing out in real world situations.  I don’t know the reticle size on this particular unit, but in the artificial light at my home it seems too tiny dim to spot well, and outside at the range it seemed bright and huge.  There is a polarizer available to try and deal with this issue, but the real solution is to use a different modern sight design.

The RX01 was pretty cool for its time, but it is obsolete now and there are far better options for the price.

And to wrap up, here is a teaser for a future optic of the week article:

The Ultimate AR15

I’ve been sorting though old photos of mine and I came across a later picture of the first AR15 I built.  Back when I decided to build it, I had decided that I would build the  ultimate AR15  One that would do everything I could possibly need it to do.

Oh boy was I naive.  Mainly about AR addiction.

Around the end of 2004, when the silly Assault Weapons Ban ended started a vast rise in the popularity and customization of the AR15.  I had been reading the AR15.com forums for a little while and decided it was time I build one.

I started with an RRA lower.  At the time they were pretty highly regarded, and it is was pretty much all I could get.  RRA tightened up the openings where the take down pins went so it was rather hard to attach or remove an upper for quite some time.  Eventually the lower wore in and is as loose as an GI gun now.

Standard GI style trigger.  We didn’t have Geissele triggers then, so there was no want for anything better.  Like most people today I didn’t care for the bump on an A2 pistol grip.  Unlike many  who were using Magpul or Tango Down grips at the time, I used an A1 grip for its slightly larger diameter combined with a Magpul winter trigger guard.  Really wanted to be ready if I had to use large gloves in Florida’s harsh winters.

This was before push button quick detach sling swivels were popular.  I don’t know if they even existed back then.  HK sling snaps were often considered the way to go.  I used CQD front and rear sling mounts.  I’m still fond of those, but I tend not to use them any more due to the much greater convenience of QD sling swivels.

I used a CAR stock on the gun.  Started with a reproduction aluminum CAR stock as I thought a metal stock would be better than plastic.  Later switched to a surplus CAR stock.  Not quite sure why, but I am still rather fond of the old CAR stock and I still use them.

Now the upper is really the heart of an AR.  At the time I decided I would go with the best, no expense spared.

So I bought a CMMG 16″ M4 upper.

CMMG was pretty highly regarded at the time.  They were being innovative, offering options many other companies didn’t, and they truly had awesome customer service.  They didn’t keep that reputation long.  A 16 inch barrel was chosen due to our laws and it still is an good compromise length for handling and velocity.  I stuck with the standard A2 flash hider.  Later AR uppers I had had Vortex, Phantom, and all many of other muzzle devices.  I tend to find unless you are mounting a muzzle break or a silencer that it isn’t worth the cost of these specialty muzzle devices.

Back then I wouldn’t have considered trying to bench rest an AR15 and shoot sub-MOA.  Wouldn’t have expected to run high power scopes, match ammo, or anything else of that sort.  I was solely familiar with the M16A2 style configuration so the whole carbine config was new to me.

I paid a little more for a chrome bolt carrier.  Chrome bolts weren’t available at the time from CMMG.  (Probably out of stock)  It can be nice to have a chromed or some other fancy finished BCG, but now days I don’t bother with the extra cost.

A Samson quad rail was chosen to free float the barrel.  One with a removable bottom rail was used so that I could easily access the barrel for cleaning, and retained the ability to mount a M203.  (Yea, I wanted a M203 back then)  The Samson rail was well made, but discontinued shortly after I got mine due to some sort of legal issues between Troy and Samson.  Their rail was good and heavy duty, and generally heavy in weight.  While it was a good product, there are so very many better choices now.

A ran a couple different rear sights.  Often I used an A1 detachable carry handle.  Sometimes a standard detachable carry handle.  Later I switched to a Troy rear sight.  The Troy is still an excellent choice.

Used my first Eotech with this rifle, a 512.  Had issues with that one draining batteries when off, and the battery contacts broke.

Wasn’t a bad configuration, but certainly far from the ultimate AR.  I still have the lower, I SBR’d it some time ago.  The upper was sold or traded off for something that would have also been sold or traded off by now.  I don’t miss it.

DI Optical’s EG1 Review: Thinking Outside the Box with a Box

Aimpoint is the only serious dot sight that anyone recommends anymore, right? Right. With the death of EOTECH’s reputation, we are left with option A for a serious duty ready red dot sight. Well, that would be the case had not D I Optical stepped into the American market. Can DIO fill the gap and bring in a quality product that gives consumers a second option to consider aside from Aimpoint?

New to the Market, Not New to the Game

If you aren’t familiar with DIO, the RV1 is the Americanized version of their service rifle red dot sight, and DIO has been making red dots of all sizes for years. See NSN# 1005-01-626-1714 for their Heavy Machine Gun Sight which is in service here stateside.

My first hands on impression with DIO was with their RV1 red dot, which I reviewed at my own blog a few weeks ago. Reaching out to DIO to show them that I beat their little red dot up and it survived, they propositioned me to beat on their EG1 red dot like I did to the RV1. I agreed.

So I took it out to the ranch, sighted in off the co-witnessed iron sights, and got to work. I threw it down multiple times, and attempted to drown it several times, and did my best to make it break. No dice. No Drama. The dot stayed on and nothing construction wise was amiss. The only problem I encountered was a loosening of the mount screws… and this was a self-made problem. I should have loc-tited it down before I even mounted it. I know better. Once I noticed that it was loosening, I ran into my shop, torqued the screws back into place, and my zero came back, and I kept on shooting. (PS: My Geiselle Mk4’s screws also started to loosen, so keep that in mind. Yes, I beat my gun that bad testing the EG1).

So with the beating, the drowning, and the overall slapping around, the EG1 performed like a red dot should… bright and always on. One of the key features of the optic is the unique form factor. As you can see, it is a square body with a square-ish 28mm lens. This unique configuration is made possible due to the prism assembly which allows the emitter to be smack dab in the base of the optic. As the emitter shines upward from the base, it is redirected by the prism to the shooter and it allows the DIO to maximize lens real estate without the emitter assembly getting in the way. Thinking outside the box with a box. It’s just crazy enough to work. I like it.

It features a battery life of 5000 hours at a medium setting… lets see, 15 total brightness settings divided by two… well let’s call that setting 8, we will round-up. The side of the optic has the windage and elevation adjustments and comes with a handy tool to adjust them, though a dime would work just the same.

It’s also mil-std 810G environment tested so we have some certification that we are getting a optic which passes some testing standards unlike many of the Chinese products on the market today. The mount itself is held in place by two hex screws, and they are big and beefy. The optic is compatible with ARMS #17 style mounts, so you have plenty of options for trading out the finger knob.

The sun shades are removable, so you can enhance the view even more. I noted that the optic is not sensitive to placement. There isn’t a “tube effect” like the Comp M4 or the mini RDS when they are mounted too close to the eye. The EG1 is just a wide open eye box. I ran it close to the rear BUIS to reduce over-the-shoulder sun glare if the heat was at my 6.

SO OVERALL

Impressions are good. This optic retails for just north of $400 bones and that is precisely in Aimpoint Pro territory. For a relative newcomer to the US market, the EG1 represents a very different approach to the RDS and its use of a prismatic assembly to widen the field of view is a novel concept. With my two DIO red dots in hand, I must say that I have started to recommend them on the forums I haunt. I hope to see more of DIO’s products in the future, and hopefully they can continue to innovate in the red dot market and add some much needed competition.

Eotech Precision Rifle Scopes Pictures

One of the products at the NRA show that was drawing a lot of attention was the new Eotech riflescopes.   Below are pictures of three of the new optics.   I examined them a little and found the glass to be really clear.   The previously posted video gives more detail on them from the rep.

 

 

 

L-3 Eotech Settlement over Fraud.

SoldierSystems.net posted up details on the settlement between L-3 and the US Government over problems with Eotech optics.

Read SoldierSystems article here.

Some of the important notes are that Eotech knew about issues back even in 2006.  Various issues include changing zeros in temperature shifts, parallax error in cold temperatures, moisture entering sights and dimming them.  Also that Eotech knew of these issues and did not disclose them to the government.
