TacFire MAR108 Anti-Walk Pin Set Black Steel AR-15

The TacFire MAR108 Anti-Walk Pin Set is a precision steel replacement set engineered to lock down the trigger and hammer pins in your AR-15 lower receiver. Without anti-walk pins, repeated firing and the spring tension of an upgraded fire control group can gradually push the trigger and hammer pins sideways out of their pockets, causing a frustrating failure that can ruin a range session. This set holds both pins positively in plane so the trigger and hammer stay exactly where they belong.

Manufactured from durable black steel and finished in a tough black coating for corrosion resistance and long service life, the MAR108 is USA made and built for drop-in fit on standard AR-15 lower receivers. The kit includes two (2) anti-walk pins, four (4) screws, two (2) hex wrenches, and one (1) guide cone, everything needed for straightforward installation to pin the fire control group firmly in place.

Whether you are running a high-performance match trigger, a binary trigger, or simply want extra peace of mind from a standard fire control group, the TacFire MAR108 is a compact, low-cost insurance policy for any AR-15 build.
