Enhanced Finger Placement (EFP) is a trigger design featuring a flat face and forward ledge that guides consistent pad placement, improving leverage, control, and split times. EFP triggers typically install as drop-in units or standard FCG sets and work with mil-spec AR-15 lower receivers (0.154″ pins), safety selector, hammer, disconnector, and trigger/hammer springs. Many versions also fit AR-10/.308 lowers that accept AR-15 pattern triggers. Compatible with any AR upper/BCG combination; no changes to buffer system required.
