Building a .308
I was starting to look into building a .308/AR-10....I started doing some basic research on parts and what not and very quickly became overhwelmed. Any advice on uppers, lowers, triggers, where to start looking, finding out which upper is compatible with which lower etc. I am brand new to this but it has been something I've wanted to do for quite some time, so any and all info would be greatly appreciated. Thanks!!
