The TacFire MAR108 Anti-Walk Pin Set Black Steel AR-15 is a compact upgrade designed to keep your AR-15’s hammer and trigger pins locked securely in place. Machined from durable steel with a black nitride-style finish, this anti-walk/anti-rotation kit helps prevent pins from drifting under recoil or spring tension, reducing wear on the lower receiver and supporting consistent trigger performance over time.
This pin set is intended for AR-15 style lower receivers and is compatible with popular drop-in triggers, including Timney units. Each kit includes two pins, four screws, two hex wrenches, and a guide cone to simplify installation and alignment of the fire control group. Ideal for range use, training, and general rifle builds where reliability and peace of mind matter, the MAR108 reflects TacFire’s focus on practical, well-made parts for the modern AR platform.
