“Of all the super safeties I've tried, the M.A.R.C from @copperhead_safety_co , and their older push button style one (currently in my belt fed) are the only ones I haven't broken/had issues with.”
“First one runs great with my Geissele, so wanted to stick with y'all. Would rather support y'all than those other guys. Plus it works, so why change?”
“I have a Copperhead MARC in my A1 clone also. Works extremely well. Bought a drop in CMMG .22LR kit, Bore Buddy trip and weight kit. Took some tuning and then experimenting to find the most reliable ammo(Remington Golden Bullet). But it's by far the gun I shoot the most now.”
