Hiperfire Xtreme 2-Stage MOD-3 AR Trigger

The Hiperfire Xtreme 2-Stage MOD-3 Trigger is a flat-bow, two-stage AR trigger built around Hiperfire’s patented Cam-Over Toggle Engine for a lighter pull without losing hammer strike energy (brand part no. X2SM3). Hiperfire tunes the first stage to a minimal, user-adjustable 2-3 lbs and adds a second-stage wall of about 1.5 lbs, for a total pull of 3.5 to 4.5 lbs depending on which included spring you run. Soft Start Lock-Up cuts down on post-break flinch, and Radical Sear Mechanics let the trigger use heavier hammer springs for better longevity and fewer light primer strikes. Semi-drop-in and made in the USA, it’s compatible with AR15, AR10, and AR9/PCC platforms, including the Sig Sauer MPX.
