PCCinator

Just FYI, Foxtrot Mike is giving me a full refund, and I bought both the upper and lower from Brownells. I'm going to give them some credit for stepping up.

Any gun that fires without pulling the trigger in the 21st Century is dangerous and defective.

This has nothing to do with the trigger or the recoil impulse. LorinB has explained the problem well, which I confirmed this weekend: The firing pin spring is too small and weak to retain the firing pin upon bolt close, and this allows the pin to light strike, and in some cases discharge a round. An EXTREMELY dangerous design flaw. He's how I tested it: I have a few thousand primed cases (I'm a handloader). Twice, I put a primed case into the chamber. Then I let the bolt close. As you can see from the photos, in both cases, the primer was dimpled. This is a design flaw, pure and simple. This gun is not safe. I contacted Foxtrot Mike on Friday 7/2 about this, but they didn't get back to me.

I, too, am having issues with an FM PCC. I bought the upper and lower separately. I had a couple of bursts today that seemed full auto, or maybe it's just my finger double tapping or triple tapping . Sure seemed like full auto and scared the *&%$#@! outta me as I hit the target hanger like some noob. I wanted to blame the new trigger; I dropped in a 3.5lbs Triggertech AR-9 this weekend, but it's not adjustable; thinking of sending it back and eating the restock. But now that I am seeing this burst issue with other people and FM's, hmm. The FM is VERY finicky with ammo. None of my target reloads feed right. I guess you have to run just hot ammo (it does say that to run over 1100fps in the manual, that of course I didn't read until after I bought the lower). Also not a fan of the side charging handle. Not a natural action charging that thing. Wish I'd just bought a CMMG. Live and learn!
