Guntec USA AR-15 Anti-Rotation Trigger/Hammer Pin Set - Anodized Black

The Guntec USA AR-15 Anti-Rotation Trigger/Hammer Pin Set is a US-made fire-control upgrade for the AR-15 platform, machined from T6 6061 aluminum and finished in a hard anodized black coating. The set replaces the standard factory trigger and hammer pins with anti-rotation locking-cam pins that capture the trigger and hammer firmly in the lower-receiver walls, eliminating the common problem of pins drifting, walking, or spinning loose under hard use or sustained semi- and full-auto fire.

Dimensionally drop-in compatible with any standard AR-15 lower receiver, the pins work across all common chamberings on the platform - .223 Remington, 5.56x45mm NATO, .300 Blackout, .308 Winchester (AR-10 / LR-308 pattern lowers), and 9mm pistol-caliber builds. Installation is straightforward: drop the pins into the lower in place of the factory pins, snug the locking set screws with the included Allen key and brass bullet-nose installation tool, and you're done. The lightweight aluminum construction adds negligible weight to the lower while giving the fire-control group a solid, locked-in feel.

Sold brand new with the Allen key, brass bullet-nose installation aid, and anti-rotation trigger and hammer pins all included. A clean, simple upgrade for any AR-15 owner looking to lock down the fire-control group.
