Took it for a spin today. About 150 rounds fired, mostly "NC rc" surplus with some silver bear. The silver bear was about twice as tight, giving 2 1/2" groups at 100 yards. The surplus stuff was pie plate at 100 yards.
On the plus side, there were zero failures to fire, zero failures to load, zero failures to eject, zero failures of any kind. Every bullet did hit the target. I used surplus and Tapco plastic mags, and made a point of resting weight on them, bending them, grabbing at them etc while shooting. The AK laughed at my efforts to stop it from working.
The Arsenal stock I got from Midway is very nice for a folder. The steel is thick enough to make a solid cheek or chin weld, and did not hurt at all. There's no real recoil with this rifle, just a kind of rattle.
I had a tough time with stances, since the ergonomics are very different and it's been many years since I've shot an AK platform firearm. I'll need to work on it. I did notice that when I had the sling tight in my arm American style, the group shifted very distinctly to the left. From what I've seen, they do not use slings like we do. They keep them loose and let them dangle, then literally toss the AK backwards to switch to a handgun. But that could be erroneous.
It's a messy gun. The surplus ball is filthy and I'm assuming corrosive. I have no rod thin enough to get into that extremely tight bore, so I must rely on a 5.56 pull-through. Seems to work well enough.
It's also pretty danged noisy, and I'm glad I wore plugs and muffs together. Ejected brass flies off into the next time zone, with enough initial force to actually bruise someone inside of a few feet.
It would be a very, very interesting round and rifle to handload for. But at the moment that's not easy to do. If Lee comes out with dies and I can snag some bullets I'm eager to see how finely tuned I can get the group. I'm willing to bet with handloads I can get inside of 2"--on par with a standard AR.
