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.

5.0 Rating Top Notch - 8/29/2014
Reviewer: Jaime C
Ordered is as a upgrade for my DPMS . The fit and finish is great fits perfect in my upper . Feels smoother then my original BCG . Paired with the hammer I'm very i pressed im not positive but the trigger pull seem lighter but for sure it has a nice crisp cleaner brake then the old hammer. Well worth the money
