weldr123's Review of Stern Defense SD BU9 9mm Bolt Carrier for AR-15 Glock-Pattern Upper Receiver

I purchased this bolt carrier and paired it with a Stern Defense MAG-AD9 AR-15 Glock 9mm/.40 Magazine Conversion Adapter. I just didn't like the Colt magazines or the Colt style conversion block. I am 100% satisfied with my purchase and would buy it again.

  • plug and play
