Overview
Built for shooters who want a refined trigger feel without giving up a duty-oriented design, this semi-automatic only two-stage trigger is aimed at precision-focused AR-15 and LR-308 setups. It uses tool steel components with wire EDM cut engagement surfaces, and the included hardened pins are intended to support durability during installation and use. With a light, crisp two-stage pull and full-power spring, it suits rifles set up for designated marksman or SPR-style roles where a cleaner break is preferred and reliability still matters. Installation instructions, a slave pin, and lubricant are included to help simplify the setup process.

Considerations & Trade-offs
- Semi-automatic only, so it is not intended for use in platforms or applications that require a different fire-control setup.
- It is a two-stage trigger with a light, precision-oriented pull, which may not suit hunters who prefer a heavier or more conventional trigger feel.
- The design is optimized for AR-15 small-pin (.154") compatibility, so fitment is limited to that specification.
- Installation is supported with included instructions and a slave pin, but this is still a trigger upgrade that may require careful fitting and setup.
