Elftmann Tactical^® ELF-SE PRO | Drop-In AR Trigger w/ PRO-LOCK™ | Straight | 2.75 lb | Black

Enhanced Precision with PRO-LOCK™ Security

The Elftmann Tactical^® ELF-SE PRO Drop-In AR Trigger builds on the proven ELF-SE platform by integrating the advanced PRO-LOCK™ retention system for maximum stability and consistency. Featuring a straight trigger shoe and a crisp 2.75 lb pull weight, the ELF-SE PRO delivers match-grade precision and repeatable performance across a wide range of AR applications—including competition, tactical use, and precision shooting.

PRO-LOCK™ Retention System

Elftmann’s proprietary PRO-LOCK™ system securely anchors the trigger module inside the lower receiver without the need for proprietary pins, thread lockers, or permanent modifications. Once installed, the system eliminates trigger movement under recoil while still allowing easy removal when needed. This design combines the simplicity of a drop-in trigger with the solid feel of a fixed-pin assembly.

Match-Grade Construction and Performance

Precision CNC-machined from A2 tool steel and aircraft-grade aluminum, the ELF-SE PRO is engineered for durability, smooth operation, and long service life. The straight trigger shoe provides a clean, linear break that promotes consistent finger placement and enhanced control. A durable black anodized finish adds corrosion resistance and a professional appearance to any AR build.

Easy Drop-In Installation

Like all Elftmann Tactical triggers, the ELF-SE PRO installs quickly into any standard AR lower receiver with no gunsmithing required. The self-contained design simplifies installation—just drop it in, secure the PRO-LOCK™ system, and enjoy a crisp, competition-ready trigger pull. Once set, the trigger remains firmly aligned through extended firing schedules.
