TacFire Anti-Walk Pin Set Features The TacFire Anti-Walk Pin Set is built to solve a common AR-15 wear issue where standard hammer and trigger pins gradually walk out of position and elongate their mounting holes in the lower receiver. By locking the hammer and trigger pins securely in place this set prevents that lateral movement and protects the receiver from premature wear. Machined from stainless steel and finished in silver the pins are corrosion resistant and built to hold up to sustained high-round-count use. Shooters running their AR-15 hard at the range or in competition benefit most from this kind of proactive receiver protection. The kit includes everything needed for installation: two anti-walk pins four screws two wrenches and one guide cone so no additional tools need to be sourced separately. Made in the USA the set is designed as a straightforward drop-in upgrade that any AR-15 owner can install without gunsmithing experience. Because the pins thread against the guide cone rather than relying on friction fit alone they stay locked in position even under the repeated recoil impulses of extended shooting sessions. For anyone looking to protect their investment in an AR-15 lower receiver this anti-walk pin set is an inexpensive way to add long-term durability.
