BCG October 23, 2024 : Doug Hall from Hot Springs, AR United States   I recently completed an AR-9 build with a BCG from another company. I had miss feeds constantly and when comparing parts with a friend's AR we noticed that the BCG was machined differently. I tried working with the "other" company with no positive results. I purchase a BCG from MAS and the issue has been resolved. MAS will have all of my business! Was this review helpful to you?
