Hiperfire Xtreme 2-Stage MOD-1 Trigger, Curved, Black

The Hiperfire Xtreme 2-Stage MOD-1 Trigger (brand part no. X2SM1) is a curved, semi-drop-in two-stage trigger finished in black Heavy Manganese Phosphate, built for AR15, AR10, and AR9/PCC variants including the SIG Sauer MPX. A short, user-adjustable first stage breaks at 2 to 2.5 pounds, followed by a minimal second-stage wall at 1.5 pounds, for a total pull of 3.5 to 4 pounds depending on whether the green or red spring is installed. The distinct wall between stages lets shooters effectively prep the trigger for added control before the clean, effortless break. Hiperfire’s Cam-Over Toggle Engine delivers lighter pull weights without sacrificing hammer strike energy, while Soft Start Lock-Up helps eliminate flinch after the break for more accurate shots at distance.
