PRO-LOCK™ Stability with Adjustable, Ergonomic Control

The Elftmann Tactical^® ELF-SE PRO Drop-In AR Trigger with PRO-LOCK™ retention system and Flat Adjustable (FA) Knob is engineered for shooters who demand both rock-solid stability and fine-tuned trigger control. Featuring a curved trigger shoe and a crisp 2.75 lb factory-set pull weight, this trigger delivers a smooth, consistent break ideal for competition, tactical use, and precision AR builds.

PRO-LOCK™ Retention System

Elftmann’s proprietary PRO-LOCK™ system securely anchors the trigger module inside the lower receiver, eliminating movement under recoil or sustained fire. This design provides the confidence of a fixed-pin trigger while preserving the convenience of a true drop-in installation—no adhesives, proprietary pins, or permanent modifications required.

Flat Adjustable (FA) Knob

The integrated FA Knob allows shooters to fine-tune trigger pull feel without removing the trigger from the receiver. This on-the-fly adjustability makes it easy to tailor performance to shooting style or conditions while maintaining consistent engagement geometry and a short, tactile reset.

Match-Grade Construction

Precision CNC-machined from A2 tool steel and aircraft-grade aluminum, the ELF-SE PRO offers exceptional smoothness, minimal overtravel, and long-term durability. The curved trigger shoe promotes natural finger placement and enhanced control, while the durable red anodized finish provides corrosion resistance and a distinctive appearance for custom AR platforms.

Easy Drop-In Installation

The ELF-SE PRO installs easily into any standard AR lower receiver. Simply drop in the self-contained housing, secure the PRO-LOCK™ system, and adjust the FA Knob as desired. Once installed, the trigger remains firmly aligned through extended firing schedules—no gunsmithing or fitting required.
