Socom bolt carrier group with a genuine 458 Socom bolt assembly. It
is highly recommended to use our brand bolt with 458 Socom uppers/barrels to
eliminate feeding and extraction issues that are common to 458 Socom's
that do not use this bolt. Our 458 Socom bolt assembly has MANY
specific, unique and purposeful features about it that other brand 458
Socom bolts do not have. These features are absolutely critical for
reliable, consistent performance in 458 Socom uppers. We have them available for purchase on our website.
