Awesome!
This BCG has to be the best bang for your buck! It comes with ock screws that are beautifully staked in place. It paired nicely with my 10.5" Ballistics Advantage barrel, I took it out and it ran flawlessly! This BCG looks to be built to last, with the Magnesium Phosphate coating I would expect years and years of abuse.

Havent taken it out to the range yet but this bcg looks great. The ocks screws, the staking, the machining all look great. Definitely plan on buying more.
