TheIron100 posted this YouTube video on muzzle devices for the AK.
I had the opportunity to examine and fire a suppressed Short Barreled Sig 556 with an AAC M4-2000 can. I did not like that setup. It’s owner pointed out that the mount of the AAC can prevented the gas system from being removed for cleaning. When the rifle was fired, gas would vent from the gap between the Sigs upper and lower receivers, and blow upwards into the shooters face. Later in the day, the owner of this rifle ended up having mechanical issue with his rifle. He ended up having to take it home to disassemble it for cleaning and maintenance.
The SBR Sig556 and the AAC M4-2000 does not make for a good combination.
I recently had a Trijicon RMR mounted on a Glock 19c. A full review will be posted later, so here are a few first impressions.
It will take some practice to get used to having an optic on a pistol. If I bring the Glock up looking for the red dot I don’t see it. If I bring it up looking for the sights, the dot is quickly visable.
The dot shows any errors in your trigger pull while your pulling the trigger. This will make this setup an excellent practice gun, and might make it a good trainer pistol when teaching people how to shoot.
The Glock with RMR will still fit in some holsters with out modification.
I do not like having threaded holes in my Glock slide. I think I would prefer is some sort of helicoil or similar insert was used to prevent possible damage to the threads in the slide. Also one of the holes extends into the channel that the extractor spring/plunger runs though.
Having a red dot on a pistol is interesting, and I will be posting more about it after I get more trigger time with this setup.
An interesting training video on the use of oil to help prevent feeding/extraction problems in adverse conditions.
I am always on the lookout for Colt stuff. Over the years I have gathered a nice little collection of colt parts and assorted collectables. Two of the nicest items in my collection I like to keep with the SP-1 since they are from the same time period and are rather hard to find. Both are new in unissued condition.
First up is a genuine colt M-7 bayonet with scabbard. It was never used and has no marks, scratches or damage.
Everyone seems to have or did have a M7 laying around at one point. Then a few years ago the interest in them soared for reasons I do not know. I assume it is over the explosion in the interest in all things “retro” related to the M16 from the 601 to the 603 series. This was given to me by a dear friend after I helped him get something he needed badly.
Next up is my personal favorite item in my collection. It is a unused Colt marked bipod that at one time would have been issued to the infantry to be used for the M16 in full auto fire from the prone. Not only is it in perfect conditon, but so is its carrying case.
Of course clamping this simple piece of kit to a barrel would destroy in hopes of real accuracy, but that is not the point. it is still a very nice bit of colts history to own though. One neat thing about its carrying case is it has a pouch on the front for the then issued sectional cleaning kit. A modern kit will not fit in the space provided on the case because the more modern sections are longer then the older VN era kits.
Finally is a poster/add from the early 90s. I bought this when I was coming up on the twilight of my teenage years. It could be purchased though the mail only since this is a few years before the internet. At least it was a few years from everyone having it and colt sure did not have a website at the time anyways. I can not remember if it was made because of the growing popularity of the cowboy action shooting or because of a re issue of some special edition SSA. But, at any rate here it is for your enjoyment and a look at how much of a packrat I am about throwing gun related stuff away.
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.
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.
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.
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.
