WOW! Sounds like you've been around the world a few times with this issue. So, would I be better off returning the Aero buffer kit and getting an Armalite AR10REKIT01 buffer kit for my DPMS Gen1 pattern receiver from LiveFreeArms.com?
Thanks for the heads up on the inbetween drilling. Am I correct that a DPMS bcg is NOT compatible with an Armalite barrel?
Because I'm already committed to the DPMS pattern, if I get one of those fucked-up barrels, I should be able to tap/plug the existing port (tap and plug, not weld; don't want to risk warping the barrel), drill out a properly-placed port, and use Armalite-branded gas tubes. That along with the Armalite buffer kit, I'm thinking I should be to Stoner spec. Yes? No?
I'm not trying to be cheap-ass to win a medal, but I AM on a limited budget.
