M16 Bolt Carrier Group (BCG) "Machined" Retaining Pin
Brand : Retro Rifles
Reproduction of the original "Machined" Retaining Pin used to hold the firing pin in the M16 carrier. This was a standard part in the original AR-15 BCG before replacement by the cotter pin (as is still used today).
Not only doe this make your BCG closer to the original, but many modern rifle shooters use it as a replacement for their cotter pin since it is a much stronger solution.
Made of Stainless Steel
