The Patriot Ordnance Factory Drop-In Curved Trigger (brand part no. 00457) is a single-stage, non-adjustable AR-platform trigger with a 4.50-pound pull weight, finished in black with red accents. Patriot Ordnance Factory pre-assembles the entire unit in a hardcoat anodized aluminum housing with rubber urethane feet, so it drops in ready for competition, hunting, or tactical use straight out of the box. The trigger, disconnector, and hammer are all carved from American A2 steel and nitride heat treated to 70 Rockwell hardness for serious strength and corrosion resistance.
