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?

My purchase AR-9 bolt carrier group July 28, 2022 : Mike Walker from BEGGS , OK United States   I try to give good rating when the object I purchase is high quality, has a good price point and quick shipping! MAS defense gets 5 stars, but I wish I could give them another! My only wish is that they had 100% stripped lowers. If they did have them I would order two today! Was this review helpful to you?
