One small detail I LOVE! August 28, 2020 Reviewer: MrBang from Riddle, Oregon, USA This is an excellent bolt carrier group. Well staked, good chrome lining. All the fun initials like MPI and stuff on it. But the ONE thing I really love about it? It has a PROPER firing pin retaining pin. If you've never seen one before, you are missing out. Colt guns have the proper pin. It is ground to a conical point for super easy reinsertion and the head is flattened so it doesn't stick out of the carrier and drag on the inside of your aluminum receiver. SO MUCH BETTER than the hardware store cotter pins that look like they were cut to length with dull wire cutters. This is the first aftermarket BCG I've ever seen that came with a real quality pin. As long as RightToBear has these in stock I'm not buying anything else!
