5.0 Rating What's your life worth? - 2/1/2014
Reviewer: Mike M.
Look we all know you should carry a back-up bolt assemble. The question is which one? Well your search stops here! This is by far the best bolt carrier group (EXO Coated) for the money. Ther are other, cheaper coated BCG's out there but don't waste your time or money. Nothing I have ever shot can come close to competing with the quality and reliability of this BCG. 1000 rounds with zero Out-of-battery issues. When your life depends on it? Buy the best.
