This is a LooseRounds.com Q&A session.  If you have a firearms related question please email it to QA@LooseRounds.com. We will post the your questions anonymously and give you our answers.

How do I zero my sights?

Howard:  Well it would help if you told us what sort of sight you are using.  With iron sights, move the rear sight the same direction you want your impacts to go, and the front sight the opposite direction you need your impact to move.

Is the LMT MWS currently for sale the same as military issue?

Howard:  No, the currently LMT MWS is not the same as what was delivered in the order of 440 rifles to the British Military.  If you want the same thing as what they have, you will need to get an early MWS with an early stainless barrel.  Since then, MWS upper has changed, the barrel profile has changed, and the bolt and bolt carrier has changed.  If you do not care about these substantial changes, and just care about the look, you can buy LMT new package called the Sharpshooter.

Who makes the decals on the Pelican case in the articles?

Shawn:  Dogfightink is where you can get the decals.

Is there a screw on front sight installation tool for Glock?

Howard:  Yes, there are several brands of hex headed screw drivers for it.  Any dealer of Glock parts should have some, and it should run you around $10.

Will a Surefire x300 fit on a Sig P226?

Shawn:  If you have a rail on your P226, yes.

Howard:  You will need to buy a rail adapters if your Sig P226 does not come with an accessory rail.

Was the M16A1 used for sniping in Vietnam?

Shawn:  It was unofficially used, and even has a recorded hit out 800m, but offically consideration and testing it was not decided to be the basis of a sniper weapon in the Marine Corps or Army.

When did the Glock Model 20 come out?

Howard:  The 10mm Glock 20 came out around 1991.

Is the Sig 517 a SR25/M110 pattern rifle?

Howard:  The Sig 517 will use the same mags as the SR25/M110.  Other then that they are different.

Do they make a 30 round clip for the Scar-H?

Shawn:  No, no one make a 30 round “clip”, or a 20 or a 5 round “clip” for the SCAR.  The SCAR uses a Magazine.

Howard:  There are aftermarket 25 round mags, I don’t know if there are 30 round mags for it.

glock 36 6 round mag

Howard:  Please use complete sentences for questions.  Standard magazines for the Glock 36 hold 6 rounds.

Is the scar breaking optics?

Howard:  Many sources state that the FN SCAR’s recoil is harsh on optics.  This may be part of the reason why EoTech moved the battery location to being transversely mounted on the new Eotech and why Elcan now has a HD line of optics.

Q&A 5

This is a LooseRounds.com Q&A session.  If you have a firearms related question please email it to QA@LooseRounds.com. We will post the your questions anonymously and give you our answers.

1.  Is it better to leave a few rounds out of magazines to save the spring?

Shawn- It is perfectly harmless to load  magazine to its full capacity. Springs wear form cycling , not from being under tension. Most of the time the problem in feeding is from faulty feed lips and not the spring.

Howard-  That started with the USGI 20 round mags which could have their spring installed backwards and would still function with 18 rounds, but would jam with 20.  Nowdays I would not buy or use mags that were not 100% reliable when loaded to capacity.

2.  What slings do  you recommend?

Howard-  First I would suggest reading Vickers article on slings.  It can be found here.  Shawn and I recommend for the AR15 slings like the Vickers sling, Viking Tactics sling, and similar 2 points.

3. How do you tighten the screws on a pre 64 Model 70 Winchester?

You tighten the front and rear screws the same as you would any other wood-stocked bolt action. but, the middle screw that holds the floor plate on is just barely tightened finger tight, just enough to let the floor plate close. if you tighten it much more it causes problems for the rifle.

4.  how do you use a weapon flash light

Howard-  Tactics and placement of a weapon light could be an article in it self.  However first a safety and employment.  I was working on a write up about it, however I found that Mas Ayoob beat me to it and did a better job.  I highly recommend looking at his article on the use of weapon lights that can be found here.

5. What is the best aimpoint for general use?

Howard- The answer depends on if you are running the aimpoint co-witness with iron sights, or without iron sights in the view of the window. If you are not co-witness with iron sights, I would highly recommend the Aimpoint T1 or H1 for its compact size and light weight. However if you are co-witnessessing with iron sights, a larger window is usually preferred. If you have the money, I would recommend the Aimpoint Comp M4, however the Aimpoint PRO offers similar excellent features at an economical price. The Aimpoint PRO is probably the best value for the person with a limited budget.

Q&A 2

This is the second session of LooseRounds.com Q&A.  If you have a firearms related question please email it to QA@LooseRounds.com. We will post the your questions anonymously and give you our answers.

Shawn and I thank Catherine Kim for the article she submitted and to thank Duncan Larsen for the articles he has submitted and for his help on our Facebook page.  We also appreciate the work CJ does as an editor on LooseRounds.com, he keeps us from looking as illiterate as we are.  Thanks also to Adam O’quinn for taking the 901 in action shots.

 

1.  How are the Surefire 60 round mags?

Howard:  Both Shawn and I own Surefire 60 round mags and we like them very much.  While we haven’t torture tested them, or run them very heavily, they appear to be good mags.  We recommend them, but be sure to test each mag before you rely on them.

2.  ar15 bolt face ring

Howard: Well that is not much of a question.  Normal wear on the bolt face may leave little pits, and a ring corresponding to the primer on the round.  If any pits extend into the firing pin channel, replace the bolt.

ARMY TM 9-1005-319-23&P and AIR FORCE TO 11W3-5-5-42 page 3-22 explain:

(a) Bolt faces with a cluster of pits which are touching or tightly grouped, covering an area measuring approximately 1,8 Inch across, will be rejected and replaced.

(b) Bolts which contain individual pits or a scattered pattern will not be cause for rejection.

(c) Bolts that contain pits extending Into the firing pin hole will not be rejected unless firing pin hole gaging check determines excess wear.

(d) Rings on the bolt face (machine tool marks), grooves, or ridges less than approximately 0.010 inch will not be cause for rejection.

3.  Winchester Model 70 used in Vietnam?

Shawn:  There were two types, one was the heavy barrel national match that had a target stock and a heavy barrel with a sporter stock.  The sporter stock model started off as sporters and then the Rifle Team Equipment (RTE) armorers added match heavy barrels.  Both were glass bedded and free floated by the RTE armors.

4.  Duty holster for 1911 with light

Shawn:  LooseRounds uses a Dark Star Gear holster kydex that can be used for IWB or outside carry.  Found it to be best of its type tested so far.

5.  scar 17 vs sig 716

Howard:  Right now you can get more parts and accessories for the Sig, such as cheap quality Magpul mags.  However as for company quality control and function out of the box, I would trust FN more then Sig.

6.  What cheap asian are good?

Howard:  Well, the following are optics and accessories are junk.  UTG, NcStar, Leapers, Counter Sniper.  Some of Tapco stuff is good, but much of it is junk.  ATI is similar with mixed quality items and plenty of junk.

Q&A Session 1

This is the first session of LooseRounds.com Q&A.  If you have a firearms related question please email it to QA@LooseRounds.com. We will post the your questions anonymously and give you our answers.

1. Aimpoint vs. Eotech?

Howard:  Shawn and I advocate the Aimpoint.  While early Eotechs were a far superior optic to early Aimpoint, modern Aimpoints easily beat Eotechs.  Aimpoints like the PRO, T-1, and Comp M4 have superior battery life over the Eotechs.  An Aimpoint will run for years while an Eotech will run for a month on a single battery.  In a recent drop test by Andrew Tuohy of http://vuurwapenblog.com/ the Aimpoint beat the Eotech.  Eotech has also had issues with battery draining while the optic is off.  Lastly, for a home defense rifle you can leave an Aimpoint on at all times so your rifle is ready to go.  I would not want to have to turn on an optic in a hurry while in an adverse situation.

2.  Will the Colt 901 take any 5.56 upper?

Shawn:  The Colt 901 will accept any 5.56/6.5/6.8/300BLK/etc upper receiver that has a small front pivot pin hole(Sorry, no old SP1 uppers will work with out an adapter).  You will need to use a mag well adapter and change out the buffer and buffer spring.

3.  Aimpoint PRO vs. Eotech.

Howard:  Ignoring the vs. Eotech part that was previously covered, the Aimpoint PRO is an great economical choice for a AR15.  Running about $400 new, it comes as a complete package ready to mount onto an AR15.  At 3/4 max brightness it will run about 3 years continuously.  You can leave this on next to your bed, or in your patrol car and know that it will be ready to go when you need it.  You can quickly adjust the brightness to be appropriated for the ambient lighting condition.  While it runs off a less common battery, you get so much longer life out of each battery it would end up costing you less then if you use an AA battery model Eotech.

4.  What is the lightest bullet for the 1 in 7 twist.

Shawn:  You can go as low as a 40 grain ballistic tip as long as it is a .224 bullet and not .223 hornet diameter, because the hornet diameter bullets have a light jacket designed to explode at a lower velocity.  Hornet bullets will not stand up to the faster twist and higher velocity.  Any quality 40 grain load will shoot just as well as any quality 55 or 62 grain load accuracy wise.  These lightweight bullets are not over stabilized and will not blow apart in flight.  That myth is from the days where people used the older light jacket hornet bullets in the new higher capacity .22 caliber cases like the .223 and 22-250.
