Great 22LR conversion pistol
Bought this for a dedicated 22LR conversion pistol, combined it with the SMMG Bravo conversion BCG, a new stripped Anderson lower, some leftover guts from previous builds, and a PSA AR15/PA10 EPT - Enhanced Polished Fire Control Group - 507797. IT WORKS GREAT! no need for a buffer tube with the 22LR ran hundreds of different types rounds through it and almost no issues (it is a 22LR). Added an el-cheap-o red dot I could not be happier with an AR pistol that my wife and pre-teen love to shoot.

Quality built
Have only put 60 rounds down it but love it. Very accurate for the 40 yards if put it too so far. Amazing finish, and looks sharp with a new brake, angled foregrip, ambi charging handle, and PSA’s NiBr bcg. Only thing is there’s a little play between it and the lower. Bought the lower and parts kit from them too.
