Nightforce has a new website.

http://nightforceoptics.com/

NightForce optics has a new web site.  NightForce scopes have been popular in both the tactical and benchrest competition crowd due to their durability and accurate tracking.  I own a NXS 2.5-10×24 and love it.

Now there are tutorial videos on how to set the NF zerostops.  This is an excellent addition because the previous printed instructions of how to set the zero stop on the compact models was not clear.

On ported Glocks

Every so often people ask about the ported Glocks.  As an owner of a Glock 19c, a ported 9mm compact, I can answer those question.

Q:  Does the porting reduce recoil?

A:  Yes, by a small amount.

Q:  Will the porting make the firearm louder?

A:  Yes, it is very noticeable firing indoors.

Q:  Does the ported 9mm Glocks shoot jets of flame from the ports?

A:  Only if you use really poor quality ammunition with no flash suppressant.  Even then, the blast from the muzzle will far surpass the blast from the porting.

Q:  Are there problems from shooting in a retention position with a ported Glock.

A:  Not if you cant the pistol slightly away from you.

Q:  Will carbon build up on the front of my front night sight?

A:  Yes, but not enough to prevent its use.(Under normal firing conditions)

Q:  Will the carbon buildup on the barrel and slide be hard to clean?

A:  No harder or longer then cleaning a standard Glock.

Q:  Is it worth getting a ported 9mm.

A:  No, however other calibers might benefit more from porting.

Notes on the FN SCAR rear sight

There is some confusion to the FN SCAR rear sight.  Hopefully this will help clear things up.

The windage is 1 MOA clicks.  There are 36 clicks of adjustment for windage, so 18 from one end will put you in the middle.

Elevation adjust is 1.5 MOA per click.  There should be enough adjustment to go below the 200m mark and have a 100m zero, and plenty of adjustment past the 600m mark.

Ideally the rifle should be zeroed with the front sight, and the rear sight left mechanically zeroed and only adjusted for wind or distance.

M855A1

Guns and Ammo posted an interesting article on the Army’s new M855A1 “green” ammo.  This confirms prior rumors of it being high pressure and inaccurate.  However there is no mention regarding the rumors that M855A1 fouls more then M855.

Sadly, it sounds like there is little good to say about the new M855A1 round.

Home gunsmithing

It is said that people who own Harley Davidson tend to think ownership means qualified to work on them.

Same thing for gun owners.  Not I am not saying that you can’t work on your own guns, but you really need to know what you are doing.

All the time at the range I see failures in AR15s from not installing the stock correctly, fire control group springs in the wrong places.  Firearms unable to be zeroed due to improper sights and sight installation.  1911 and revolver triggers get tuned to the point of unreliability.

I have to be honest, I have done this my self.  Had the buffer retaining detent pop up and cause the hammer to not hit the firing pin.  Had a connector sold to me as “glock brand” cause reliability issues.  Broken screws and bolts using improper torque values.  The list goes on.

Many modern firearms are simple to work on.  However simple to work on does not equal fool proof.  Make sure you know what you are doing when you work on your firearms, and if you are not sure, get an experts help.

Optics report from the range.

Saw a Nikon elevation turret break off today.  There was no visible abuse to the scope, and the adjustments appeared to be working previously.   I have never seen a failure like that before, but it reminds me why paying more for some brands is well worth it.

I got to try a Sightron 6-20 power scope today.  The Sightrons are gaining popularity here as a cheaper alternative to Nightforce and Leupold.  I am not sure which model it was I was given the chance to use, but the clarity was great from 6-about 14-16 power.  As the power was brought up to 20x, the picture clarity and crispness declined.  At this point I do not think I would recommend a Sightron for a fighting rifle.  However for a range gun or target/competition rifle, it may be an excellent economical choice.

Update:

I also got to look through an IOR 2-12 power scope.  I believe the model was the Spartan.  What I thought was most interesting was how compact this scope is.  Many tactical scopes end up being large.  A 3-15 or 5-20 tactical scope can be rather large and heavy on a smaller rifle like an AR15.  This smaller scope would be right at home on a smaller lighter rifle.  The power range is also good for closer range work.  I have found that shooters(including my self) are slower at finding close target with 5x and up.  The top end of 12x along with the scopes clarity allowed me to easily find and see 8 and 10 inch steel targets at 1000 yards.  This compact scope appears to be one of the ideal choices for the compact lightweight 5.56 or 7.62 sniper system.

Aimpoint vs. Eotech for the home defense rifle

Both Aimpoint and Eotech are popular reflex optics for the AR15 family of weapons.  Constantly online and there are heated debates over which is the better optic and many people have differing opinions for different reasons.  There is one major reason the Aimpoint should be picked over the Eotech for home defense.  This is the Aimpoints battery life and run time.  An Eotech needs to be turn on before use, and will run 4 or 8 hours before shutting down.  The Aimpoint will run months to years depending on model and brightness.

The Soldier or the police officer when going on duty or starting a patrol has the time to turn on an Eotech.  You don’t know when you might need to use a home defense rifle, and you shouldn’t want to have to turn on its optic before you can use it.  Even worse would be if your battery is dead when you need it.  The new Eotech EXPS3 has a listed battery life of 25 days on setting 12.  The new $400 dollar Aimpoint PRO will run 3 years on 3/4 max brightness.

Back when I owned an Eotech 512, I often found the batteries were dead when I wanted to use it.  I had to store the batteries out of the optic to keep them from draining.  Not only did I have to turn it on before I would shoot, I would have to check during the day that it is still on.  When working at the range, I have seen more then a few shooters day at the range ruined when the only rifle they bought has an Eotech with dead batteries and no iron sights.

If your rifle is a fun gun, get the optic you prefer.  But if you require a reflex sight that is ready all the time, use an Aimpoint.
