The Patriot Ordnance Factory EFP Single-Stage Trigger, 4 lb, Black Hardcoat Anodized, AR-Platform (brand part number 00516) uses a forward Enhanced Finger Placement design that naturally guides the fingertip to the same resting spot for a precise, consistent pull every time. Patriot Ordnance Factory builds this single-stage, non-adjustable trigger with a solid 4-pound pull weight in a hard-coat anodized aluminum housing with rubber urethane feet, ready for competition, hunting, or tactical use right out of the box. The trigger, disconnector, and hammer are cut from American A2 tool steel and nitride heat-treated to 70 Rockwell case hardness for strength and corrosion resistance, and the kit includes custom-fit stainless steel KNS Precision anti-walk pins for both standard AR and POF USA ambidextrous lower receivers. It will not fit inside a DPMS lower.
