Killer Bolt Head
Had issues for weeks with my AP5. As most forums claim it is never the bolt head: for me it was the bolt head. After changing literally every other part and still continuing to encounter double feeds after 300 trouble laden rounds, decided to give this a shot. First mag of 30 rounds in semi auto, full function. Second mag in FRT mode, zero issues. Will 100% be recommending this to anyone who has chased problems with all the obvious parts and not had resolution.
