burnt my comp

Shay1911 Jan 13 2009, 07:11 AM Just a warning from personal experience. I have around 600 rounds of PMC ammo through my AR. It burnt the ____ out of the first chamber of my comp. It is pitted with lots of erosion. I'd rather not say which comp it is, but it is a top quality one. I hope this helps someone. lmccrock Jan 13 2009, 07:34 AM I have run hundreds (500+) of PMC Bronze through my comp'ed rifle. While the comp has been blackened inside, it is no worse than the other ammo I have run (mostly Remington UMC and Fed XM193). Have you run any other ammo through it? Contacte
