PRO-LOCK™ Stability with Tunable Trigger Control

The Elftmann Tactical^® ELF-SE PRO Drop-In AR Trigger with PRO-LOCK™ retention system and Flat Adjustable (FA) Knob is designed for shooters who demand rock-solid stability with the ability to fine-tune trigger feel. Featuring a curved trigger shoe and a crisp 2.75 lb factory-set pull weight, this trigger delivers a smooth, predictable break across competition, tactical, and precision AR builds.

PRO-LOCK™ Retention System

Elftmann’s proprietary PRO-LOCK™ system locks the trigger module securely inside the lower receiver, eliminating movement under recoil or high round counts. This design delivers the confidence of a fixed-pin trigger while retaining the simplicity 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 adjust trigger pull feel without removing the trigger from the receiver. This feature provides fast, user-friendly tuning 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 delivers exceptional smoothness, minimal overtravel, and long-term durability. The curved trigger shoe promotes natural finger placement and enhanced control, while the black anodized finish provides corrosion resistance and a clean, professional appearance for any AR platform.

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 fine-tune the FA Knob as desired. Once installed, the trigger remains firmly aligned through extended firing schedules—no gunsmithing or fitting required.
