    5 of 5 Love MI's BCGs May 6, 2020
    Reviewer: Andrew from Cedar Falls, IA United States  
    I've used a couple other BCGs in my ARs, but these feel and perform the best. Can't go wrong.

    5 of 5 Awesome product, fast shipping April 24, 2020

    This is a great BCG and everything came exactly in spec. I like the nickel boron because it is so much easier to clean.
