[QUOTE="C-130 Dude, post: 2509445, member: 122991"] I have built 18 of these large frames ar308/10 type guns. Every one of them have had pierced primer problems. The only way I have been able to mitigate this problem was to install a JP high pressure bolt assembly. The smaller firing pin works. No, I don't get $$ from them to state this. Messing around withe gas system can induce REAL nightmares. I did this on the first couple of guns and finally learned my lesson. My advise, stay with a rifle length gas system. Note that the gas tube length of an Armalite AR10 and the AR308(dpms style) are different lengths. I found this out the hard way. Large frame AR guns require lots of patience to build and wring out the problems. Different weight buffers and different rate spring are essential to balance your system. Good luck. [/QUOTE]
