Elftmann Tactical^® ELF APEX PRO SE | Drop-In AR Trigger w/ PRO-LOCK™ | Curved | Red

APEX Responsiveness with PRO-LOCK™ Security

The Elftmann Tactical^® ELF APEX PRO SE Drop-In AR Trigger delivers lightweight, competition-ready performance reinforced by Elftmann’s PRO-LOCK™ retention system. Featuring a curved trigger shoe and a crisp 2.75 lb factory-set pull weight, this trigger provides a smooth, predictable break designed for precision, speed, and control across all AR platforms.

PRO-LOCK™ Retention System

Elftmann’s proprietary PRO-LOCK™ system secures the trigger module firmly inside the lower receiver, eliminating movement under recoil or extended firing schedules. This design delivers the confidence of a fixed-pin trigger while preserving the simplicity of a true drop-in installation—no adhesives, proprietary pins, or permanent modifications required.

Curved APEX Trigger Geometry

Built around Elftmann’s APEX trigger geometry, the APEX PRO SE emphasizes minimal take-up, a clean break, and a short, tactile reset. The curved trigger shoe enhances natural finger placement and comfort, supporting consistent control and faster follow-up shots during high-tempo shooting.

Match-Grade Construction

Precision CNC-machined from A2 tool steel and aircraft-grade aluminum, the APEX PRO SE delivers exceptional durability while maintaining reduced mass for fast trigger response. The red anodized finish provides corrosion resistance and a bold, professional appearance for custom AR builds.

Simple Drop-In Installation

The self-contained APEX PRO SE installs easily into any standard AR lower receiver. Drop the trigger module into place, secure the PRO-LOCK™ system, and you’re ready to shoot—no gunsmithing, fitting, or permanent modifications required. Once installed, the trigger remains stable and aligned through extended use.
