The Hiperfire X2S MOD-1 Two-Stage AR Trigger (Hiperfire part no. X2SM1) is a semi-drop-in two-stage trigger for AR-15, AR-10 and AR-9/PCC rifles. Hiperfire gives the MOD-1 a longer first stage than the MOD-2 or MOD-3 for a more defined first-stage prep, on a curved bow with a heavy manganese phosphate finish. The X2S family carries the technology Hiperfire is known for, including Radical Sear Mechanics, a Cam-Over Toggle Engine and user adjustable pull weights. It suits a shooter who likes to prep the first stage before the break.
