is proud to offer our improved 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.
we have developed an improved extractor with geometry that provides a
repeatable and reliable extraction of spent cases. Also included is our already
very popular upgraded firing pin. This 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.
guide rod and ejector pin geometry and locations have been optimized to ride in
their respective channels with as little resistance possible. Finally, we have
included an optimized buffer pad printed from TPU to perfectly fit the pins and
dampen the impact of the bolt during the rearward motion (due to supply chain
constraints buffer pads may be either white or black, both colors are of
similar durometer and will function similarly).Bolts come fully assembled ready to drop into an upper or similar design.
Bolt assemblies are currently excluded from discounts and promotions.
