[QUOTE="QuietTexan, post: 2298197, member: 116181"] Yeah but 300 BLK has significantly more bullet mass for the gas charge to move without pushing the bullet past the speed limit. JP Enterprises makes a gamer kit - low mass BCG, buffer, and spring, but even then I would think the port would have to be huge. 0.093" port and a switchblock so it doesn't flame thrower your face with a super? I'm not one to complain about a gassy AR but with realistically an 80gn max bullet it seems like it's going to be a specialized rig once it's put together, not one to just drop the 20" upper on without changing out parts.
