Luth-AR .308 Firing Pin

The Luth-AR .308 firing pin is a direct-fit replacement pin built for .308-pattern AR rifles, the small but essential part that strikes the primer to fire every round. Luth-AR built its reputation on AR-15 and AR-10 lower parts and stocks, and this firing pin follows the same mil-spec dimensions so it drops into a compatible bolt carrier group without hand-fitting. Builders assembling a .308 upper from individual parts, or anyone replacing a worn or lost firing pin, both need this exact component to keep the rifle running reliably. It’s a low-cost part that’s easy to overlook until the rifle won’t fire.
