5.56 Timeline

News from the range.

Many people prefer to shoot on private property alone for a variety of good reasons.  However when you go to the public ranges, you can see all sorts of interesting gear and meet a variety of interesting people.

Accuracy International AW50

I got to fire an Accuracy International AW50.  This sniper system came with S&B 3-12X scope, 10 mags, 3 muzzle breaks, and a hard case that could be parachute dropped.  The most interesting things about it were its hydraulic recoil reduction system, and the muzzle break.  The combination of break and hydraulic buffers makes the rifle very pleasant to shoot, and makes it easier to spot your own impacts.  The large muzzle break was similar to the JP recoil eliminator break.  It send the blast from the .50 out to the sides, so unlike most .50 BMGs where being behind the shooter is the only good place to be, it wasn’t bad being alongside the shooter(You still don’t want to be in line with the muzzle).  I really want one now.

I often talk about problem and broken guns here.  Usually it is pretty apparent when someone has an issue with a firearm.  For example, a when someone dropped a .22 Long Rifle into a .22 Hornet, it looks sort of like this:

It can be hard to get someone to believe that their firearm is broken, when it still is working reliably.  One of our regulars was talking to me about his Glock, and had it apart while we were discussing 9mm conversions for .40 cal Glocks.  Looking it it, I noticed that the extractor had broken, but I had a hard time convincing him of that because his pistol was still running well.  Finally I managed to get him to buy a new ejector.  This picture shows the new and old broken ejectors side by side.

This last photo is an interesting issue where a MGI 7.62×39 bolt and firing pin were piercing primers.  The firing pin was occasionally cutting a clean hole in the primer.  I told the owner to contact MGI.  It will be interesting to hear about what they tell him.

As for interesting people, some of the guys I had seen out that and talked to turned out to be the guys from NFA Review.  I have previously seen some of their videos and rather liked them.  Also it is on of their suppressors reviews is what helped a family member of mine pick the Silencer Co Octane 9.  I find it interesting that the Octane 9 is easier to clean then the AAC Trident.

Here is one of my favorite videos of theirs:

Suppressed Sig 556


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.
