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

APEX Speed with PRO-LOCK™ Retention

The Elftmann Tactical^® ELF APEX PRO SE Drop-In AR Trigger blends the lightweight responsiveness of the APEX trigger design with the added security of Elftmann’s PRO-LOCK™ retention system. Featuring a curved trigger shoe and a crisp 2.75 lb factory-set pull weight, this trigger delivers smooth, predictable performance for competition, tactical, and precision AR builds.

PRO-LOCK™ Retention System

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

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 comfort and natural finger placement, supporting consistent control and fast follow-up shots.

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. The black anodized finish provides corrosion resistance and a refined, understated appearance that complements any AR platform.

Drop-In Installation Made Simple

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.
