But my buddy travis can do sub-MOA @ 100yrds with his bull barrelled 10/22

I'm jealous.

I got to tune the AR pistol and the new 16" PSA standard AR. I let the boy shoot the pistol @25 yards with some M855. Needless to say on that AR500 steel target, the M855 made an impact that sent bursts of stars and sparks all over the place One impact had a grapefruit sized ball of sun at impact that was quite spectacular. It actually created small craters where it hit But I had to be certain the pistol would feed it without any issues. It passed but it won't feed steel cased Wolf ammo at ALL... Any help with that nhgunnut? Phase 5 pistol tube and spring, so the springs set up for pistol action.
I haven't played with AR Pistols that much, but the geometry of the round is the same between manufactures . You don't mention what the pistol is doing but My guess is short stroking. The round fires but either doesn't eject or more likely doesn't feed the the next round reliably. The first question is how badly do you want to run cheap ammo? You culprit is most likely that wolf and (most of the Russian 223 rounds ) are loaded weaker than their western counterparts. Options in order of what I would try.
1 Decrease the Buffer Weight. ( you can buy a lighter buffer or do what I would do and knock the role pin out of the buffer, remove weight and fill the space with something light weight)
2 Try a lighter spring (or cut a coil) The caution to both of these fixes would be increased perception of recoil with the hotter US rounds. And if you see signs of over gassing like the bolt no locking back or damage to the case head you have gone to far.
These first 2 fixes can easily be undone with simple parts swaps and if you find a setup that works , you are free to keep 2 springs and 2 buffers that work with the ammo of the day. This last one is a all or nothing.
3 Last and I don't recommend it unless you have a spare barrel , is to take the barrel it to someone skilled and open the gas port slightly. I would really hesitate before I did that
Hope it helps
