Mac-11 compatible bolt assembly. The body of these bolts are machined from high quality steel then case hardened to 55 RC making them extremely durable.
Bolts are equipped with an improved extractor that provides a repeatable and reliable extraction of spent cases. The upgraded firing pin is turned from 17-4 Stainless Steel and heat treated to condition H900 making it the strongest available firing pin for the mac 11 platform.
The guide rod and ejector pin geometry and locations have been optimized to ride in their respective channels with as little resistance possible.
Bolts come fully assembled ready to drop into an upper or similar design.
