3 lb Sierra Performance Trigger
The included drop-in Sierra trigger system delivers a crisp 3 lb trigger pull with an exceptionally short reset for fast, accurate follow-up shots. Designed with a smooth single-stage feel that blends characteristics of both traditional single-stage and two-stage triggers, it provides excellent control without sacrificing reliability. The skeletonized components reduce unnecessary weight while maintaining dependable ignition, making this trigger an outstanding choice for competitive shooting, range use, and performance-oriented rifle builds.
Ambidextrous Safety Upgrade
Replacing the standard selector with an ambidextrous safety dramatically improves rifle manipulation for both right- and left-handed shooters. The dual-sided design allows quick engagement and disengagement from either side of the receiver while accommodating a variety of shooting positions and grip styles. Compatible with both AR-15 and LR-308 platforms, this ergonomic upgrade enhances control without adding unnecessary complexity to the rifle.
Minimalist Lower Parts Kit
The included minimalist lower parts kit contains every essential lower receiver component except the trigger, hammer, and safety selector, allowing builders to install premium upgrades without paying for unused factory parts. It includes the bolt catch assembly, magazine catch assembly, trigger guard, pivot and takedown pins, buffer retainer components, springs, detents, installation hardware, and a Mil-Spec A2 pistol grip. This streamlined approach makes it an ideal companion for premium trigger systems and custom rifle builds.
Follow safe handling and manufacturer instructions. Ensure compliance with all applicable laws. Verify compatibility with your specific lower receiver before installation. All components are designed for standard mil-spec AR-15 platforms.
