I've read a bunch of threads on this, and now I'm confused... Some people say it's a milspec buffer, some comercial, some measured it and say it's neither. If you buy the adaptor from Fabsports, will any stock fit? Some guys are saying you can't use the new buffer tube, just the plastic bits. Can someone tell me once and for all? I'm just asking about the stock here, not handguards and flash hiders.
