The Hiperfire HF AR15/10 Drop-In Trigger MCX brings the company’s proven PDI single-stage design to the SIG MCX platform in a compact, self-contained module. This curved trigger delivers a crisp, consistent break with a light pull weight, while the Blacknitride+ treated components provide a smooth feel and added corrosion resistance. Built as a true drop-in kit, it installs easily without gunsmithing so you can upgrade your MCX with minimal downtime.

Designed for demanding shooters, this trigger combines a MIL-grade hammer strike with PCC blowback-tough construction, hammer collision bumper, and enhanced disconnector protections to handle high round counts. The distinctive curved bow with HIPERSHOE finger pad helps you index your finger the same way every time, supporting precise control for range work, training, or competition. It reflects Hiperfire’s focus on refined geometry, durable materials, and thoughtful engineering for modern rifles.
