PSA Pigsticker and Rainier XTC Comp Update

A while back, I bought a Pigsticker compensator from Palmetto State Armory, and put it on a 10.5" barrel.  Although it seemed to work fine, the muzzle flash was ridiculous. (Original Post)

Yesterday, I swapped the comp over to my 16" Spike's Tactical 5.45x39mm upper, and today I took it out to do some shooting.  Unfortunately, all is still not well.  The comp shoved the muzzle down hard and to the left.  I also couldn't get the tip of my pull-through cleaning rod out through the end of the comp.  No flash that I noticed, though.

The Rainer XTC did fare much better.  While I had the barrel vice blocks out, I put the XTC on my LMT 16" M4gery  Although there is a bit of concussion, there was no tuning fork "ting," and not too much muzzle lift.  Unfortunately, I had another Tula steel shell case get stuck hard in the chamber, cutting short that shooting session.  Even if I had a cleaning rod, it took a half dozen hard hits with a dead-blow hammer to remove it.

Semi-semiautomatic AR-15

No, I didn't type the title for the post with a stutter.  Southern Gun Company of Cornwall, England developed an AR-15 style 9mm rifle that locks the bolt back with every shot.  The shooter can then release the bolt with a lever put in place where the safety lever would normally be.  It probably sounds more awkward than it is in practice.  Check out the video of the SGC Unicorn rifle in action.

There shouldn't be a need for these shenanigans, but there are, regardless.  I find this solution to an unnecessary problem to be brilliant.  If I were stuck living behind enemy lines in a ban state, I would be trying to do something like this over a "featureless" build, or a bullet-button, or a fixed magazine, or any of that other nonsense.

Beats having to manually operate the bolt like a bolt-action rifle, which is what U.K. shooters have been doing with AR rifles.
