The Luth-Ar Vintage Style AR-15 Firing Pin Retainer Chrome brings back the original AR-15 firing pin retainer design developed in the early days of the platform. Machined from durable 1045 carbon steel and finished in a matte chrome plating, it replaces the standard cotter pin to securely capture the firing pin in standard AR-15 bolt carriers while offering a clean, retro look for classic builds.

This firing pin retainer is ideal for shooters building or maintaining AR-15 rifles chambered in .223 Remington or 5.56x45 NATO, especially those focused on vintage-style or M16 A1 clone projects. Its snug fit and open slot design allow the user to achieve the desired tension for reliable operation during range use, training, or general recreational shooting. Luth-Ar is known for thoughtful AR-15 components that blend proven engineering with attention to detail.
