: Brian Kliem from Spring, TX United States
I couldn't wait to get my BCG in for my AR. I am building my from the ground up and purchased most of my parts from MAS. The BCG looks badass with my all black 300 blackout and the performance spot on. Great company for all your firearm needs, which is why it's my go to first when purchasing for my assembly.
