Guntec Perma-Pin Firing Pin Retainer PERMA AR10 .308 BCG Firing Pin Retainer
Replaces standard cotter pin found in the bolt carrier to retain the firing pin as in original Stoner rifles. The cotter pin is difficult to install at times and is subject to breaking.
I love "one and done" solutions to common problems, and that's why the perma-pin is a must have!
A firing pin perma pin, like the KNS Perma-Pin, offers the advantage of being a more reliable and convenient way to retain the firing pin in a firearm compared to a standard split cotter pin, as it eliminates the risk of the pin shearing or becoming bent, making it easier to assemble and disassemble the bolt carrier while ensuring the firing pin stays securely in place.
Key benefits of a firing pin perma pin:
Improved reliability: Due to its solid design, a perma pin is less prone to failure or loosening over time, which can potentially cause firing pin issues.
Easy installation and removal: Unlike a split pin that can be difficult to align and insert, a perma pin simply pushes in and out, making field stripping and reassembly quicker and smoother.
Reduced maintenance: With a perma pin, there's no need to worry about replacing a worn-out cotter pin, minimizing maintenance needs.
Consistent tension: A well-designed perma pin provides consistent tension on the firing pin, ensuring proper strike on the primer.
