Aramfan2's Review of CMMG 22LR Mk4 Barrel Kits w/ Collar
Some reliability issues up front. Polished feed ramp and chamber. That got Federal ammo running 100%. The mags in ar's rock forward and back a bit, found out by rocking the mag forward, shoots any ammo 100%, rem, win, cci, etc. (I have 4 mags, dif mfr, all the same) currently using a wood wedge at the back, but will JB two mags. Running a Cosmic suppressor on it. Very, very accurate. Was worth the fiddling.
