Elftmann Tactical® ELF-SE PRO | Drop-In AR Trigger w/ PRO-LOCK™ & FA Knob | Straight | 2.75 lb | Red
PRO-LOCK™ Stability with On-the-Fly Adjustability
The Elftmann Tactical® ELF-SE PRO Drop-In AR Trigger with PRO-LOCK™ retention system and Flat Adjustable (FA) Knob delivers unmatched stability, control, and user customization across all AR platforms. Featuring a straight trigger shoe and a crisp 2.75 lb factory-set pull weight, this trigger is engineered for shooters who demand precision and adaptability in competition, tactical, or precision rifle applications.
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 solid feel of a fixed-pin trigger while maintaining the simplicity of a drop-in installation—no adhesives, proprietary pins, or permanent modifications required.
Flat Adjustable (FA) Knob Control
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 personal preference or shooting conditions while maintaining consistent engagement and reset characteristics.
Match-Grade Craftsmanship
Precision CNC-machined from A2 tool steel and aircraft-grade aluminum, the ELF-SE PRO offers exceptional smoothness, minimal overtravel, and a fast, tactile reset. The straight trigger shoe promotes consistent finger placement and a clean, linear pull for enhanced control. A durable red anodized finish provides corrosion resistance and a distinctive appearance for custom AR builds.
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.
