The Patriot Ordnance Factory Drop-In Trigger (brand part number 00858) is a single-stage, non-adjustable trigger pre-assembled in a hard-coat anodized aluminum housing and finished with a black and red flat trigger shoe. It ships with a solid, fixed 3.5-pound pull weight, ready for competition, hunting, or tactical use straight out of the box with no tuning required. POF carves the trigger, disconnector, and hammer from American A2 steel and nitride heat-treats every one to 70 Rockwell case hardness, giving the internals serious strength and corrosion resistance for a long service life.
