POF EFP Drop-In Trigger – Black Hardcoat Anodized

The Patriot Ordnance Factory EFP drop-in trigger is an AR-platform replacement designed around Enhanced Finger Placement (EFP) geometry to encourage a consistent finger contact point for repeatable trigger pulls. The assembly installs as a drop-in unit and uses a hardcoat-anodized housing with urethane feet for seated fitment. Internal components are cut from hardened tool steel with corrosion-resistant surface treatment, and the kit includes stainless steel KNS anti-walk pins for compatible lowers. Note: this trigger will not fit DPMS lower receivers.
