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

Lightweight APEX Performance with PRO-LOCK™ Security

The Elftmann Tactical^® ELF APEX PRO SE Drop-In AR Trigger combines the fast, lightweight characteristics of the APEX trigger design with the added security of Elftmann’s PRO-LOCK™ retention system. Featuring a straight trigger shoe and a crisp 2.75 lb factory-set pull weight, this trigger delivers a clean, consistent break well-suited for competition, tactical use, and precision-oriented AR builds.

PRO-LOCK™ Retention System

Elftmann’s proprietary PRO-LOCK™ system anchors the trigger housing firmly inside the lower receiver, eliminating movement under recoil or extended firing schedules. This design offers the solid feel of a fixed-pin trigger while retaining the simplicity and convenience of a true drop-in installation.

APEX Geometry for Speed and Control

Built around Elftmann’s APEX trigger geometry, the APEX PRO SE emphasizes minimal take-up, a smooth break, and a short, tactile reset. The straight trigger shoe promotes consistent finger placement and a 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 delivers excellent durability while maintaining reduced mass for faster trigger response. The black anodized finish enhances corrosion resistance and provides a clean, understated appearance that complements any AR platform.

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 modification required. Once installed, the trigger remains stable and aligned through extended use.
