Here's a couple of pics of my 308 pistol build with the 12.5 inch Sig barrel. The brace is an SOB brace, Diamondback blem receiver set, Sig barrel, Sprincco orange spring and a 5.4 oz. buffer, CMMG 9.5" hand guard, LaRue MBT2 trigger, Magpul MOE+ grip, D. Wilson BCG, White Oak Armament 10 & 5/8" gas tube with a PAW adjustable gas block and an Aimpoint Comp M4s. I put the adjustable gas block on because I plan on shooting it from time to time with a suppressor on it. I had extraction issues at first, which was an issue for a couple of the guys on here back when we bought these BCGs from Dave Wilson. I solved it by doubling up on the rubber o rings on the extractor springs. After that, I ran 120 rounds through it with no problem just to break it in. Next step, get it on paper and see what it will do! I dialed the gas block 3 clicks past where I got BHO and the recoil is pretty decent!
