TacFire MAR108SS Anti-Walk Pin Set Silver Stainless Steel AR-15

The TacFire MAR108SS Anti-Walk Pin Set is an American-made stainless steel upgrade for your AR-15 lower receiver, purpose-built to keep your trigger and hammer pins locked firmly in place. Standard roll pins on Mil-Spec AR platforms tend to drift outward under repeated firing, eventually elongating the pin holes in the receiver and creating real reliability headaches; the MAR108SS replaces those pins with a captive anti-walk design that eliminates that movement entirely.

The set includes two stainless steel anti-walk pins, four set screws, two installation wrenches, and a guide cone for straightforward installation. The corrosion-resistant silver stainless finish pairs nicely with polished or stainless receivers and matches the look of other bright AR components.

Installation is simple: drop the anti-walk pins in place of your existing trigger and hammer pins, snug the set screws down with the included wrenches using the guide cone for alignment, and you're back in business. The MAR108SS fits most Mil-Spec AR-15 lower receivers and is proudly Made in the USA.
