Elftmann Tactical Anti-Walk Anti-Rotation Trigger & Hammer Pin Set AR-15/AR-10/M16 - Black Oxide

The Elftmann Tactical Anti-Walk, Anti-Rotation Pin Set is a direct-replacement hammer and trigger pin upgrade built for the AR-15, AR-10, and M16 family of rifles. Elftmann designed these pins to solve the two most common headaches that show up after a quality drop-in trigger install: pin walk under recoil and pin rotation that lets the trigger group shift in the lower receiver.

Each pin is machined from hardened American steel and finished in a low-profile black oxide coating for corrosion resistance and a clean, factory-style look inside the receiver. The pins lock the trigger and hammer in place so the group cannot drift out of the lower, even under hard use on the M16 platform or the abuse of a competition carbine. At a standard 0.1535" pin diameter, they drop right into any mil-spec AR-15/AR-10 lower receiver without any fitting.

Installation is straightforward: remove the factory trigger and hammer pins, drop the Elftmann pins in their place, and close the receiver. The flat end of each pin is designed to line up with the "D"-shaped holes on the back plate of the trigger housing for clean removal during fieldstripping or future trigger swaps - no punches, no drift, no frustration.

Stronger than the standard trigger and hammer pins they replace, the Elftmann Anti-Walk Pin Set is a smart insurance upgrade for any AR-platform owner running a drop-in trigger, or anyone who has ever watched a factory pin drift on a high-round-count build.
