Patriot Ordnance Factory EFP AR-15 4 lb Single-Stage Straight Drop-In Trigger - Black

The Patriot Ordnance Factory EFP (Enhanced Finger Placement) is a single-stage, straight-shoe drop-in trigger purpose-built for the AR platform. POF engineered the EFP to deliver a clean, crisp break with a short reset, giving AR shooters a refined trigger pull that enhances accuracy and tightens split times on follow-up shots.

Pre-assembled and non-adjustable, the EFP produces a solid 4-pound pull weight right out of the box. The internal components are steel, while the drop-in cassette rides in a black hardcoat anodized aluminum housing for durability and corrosion resistance. The trigger is ambidextrous in operation and uses non-rotating trigger and hammer pins for reliable, wobble-free performance.

Installation is straightforward: drop the assembly into the lower receiver group and secure it using the included KNS Precision anti-walk trigger pins. No permanent modifications are required, making the EFP a quick, drop-in upgrade for any standard AR-pattern rifle or pistol lower.
