Elftmann Tactical® ELF APEX PRO SE | Drop-In AR Trigger w/ PRO-LOCK™ | Straight | Red
APEX Performance with PRO-LOCK™ Stability
The Elftmann Tactical® ELF APEX PRO SE Drop-In AR Trigger merges the lightweight, fast-reset characteristics of the APEX trigger with the enhanced retention of Elftmann’s PRO-LOCK™ system. Designed with a straight trigger shoe and a crisp 2.75 lb pull weight, this trigger delivers a clean, predictable break ideal for competition, tactical, and precision-focused AR builds.
PRO-LOCK™ Retention System
Elftmann’s proprietary PRO-LOCK™ system securely anchors the trigger housing inside the lower receiver, eliminating movement under recoil or sustained fire. This design provides the confidence of a fixed-pin trigger while retaining the convenience of a true drop-in installation—no adhesives, proprietary pins, or permanent modifications required.
Lightweight APEX Geometry
Built around Elftmann’s APEX trigger geometry, the APEX PRO SE emphasizes speed and consistency with minimal take-up and an exceptionally short, tactile reset. The straight trigger shoe promotes uniform finger placement and a clean, linear pull, supporting fast follow-up shots and repeatable accuracy.
Match-Grade Construction
Precision CNC-machined from A2 tool steel and aircraft-grade aluminum, the APEX PRO SE offers excellent durability with reduced mass for faster trigger response. A durable red anodized finish enhances corrosion resistance and provides a distinctive appearance for high-performance AR platforms.
Easy Drop-In Installation
The self-contained APEX PRO SE installs easily into any standard AR lower receiver. Simply drop in the housing, secure the PRO-LOCK™ system, and you’re ready to shoot. No gunsmithing or fitting is required, and once installed, the trigger remains firmly aligned through extended firing schedules.
