TacFire MAR121-P Firing Pin Retainer 5.56/9mm Stainless Steel

TacFire Firing Pin Retainer Features The TacFire Firing Pin Retainer locks the firing pin securely within the bolt carrier preventing it from shifting out of position during cycling. Compatibility with both 5.56 and 9mm bolts makes this single part useful across multiple builds reducing the need to stock separate retainers for each caliber. Stainless steel construction resists corrosion and wear standing up to the heat and fouling generated inside the bolt carrier group. Its small precise dimensions ensure it seats properly without interfering with bolt function. At 0.75 long 0.2 tall and 1.3 wide the retainer is sized to drop directly into place as a replacement for a lost bent or worn factory pin. Keeping a spare on hand is a simple way to avoid downtime from a failed retainer during range sessions or competition. The part s low cost and small size make it practical to carry as part of a basic spares kit. This retainer suits AR-15 and 9mm AR-platform owners performing routine maintenance or repairs on their bolt carrier groups.
