Premium Drop-In Match Trigger

The included drop-in trigger assembly delivers a crisp 3 lb trigger pull that provides significantly improved control over traditional Mil-Spec trigger systems. Its self-contained cassette design simplifies installation while producing a clean break and short reset for faster follow-up shots. The skeletonized hammer and trigger reduce unnecessary weight while maintaining the strength required for dependable operation, and the distinctive crimson red finish adds a custom appearance that stands out from standard factory components.

Lightweight Lower Parts Kit

Rather than including a standard fire control group that would immediately be replaced, this lightweight lower parts kit omits the trigger components while supplying every other part required to complete your lower receiver. The kit includes the safety selector, bolt catch assembly, magazine catch assembly, trigger guard, takedown and pivot pins, buffer retainer components, springs, detents, installation hardware, and a Mil-Spec A2 pistol grip. This streamlined configuration eliminates wasted parts while giving builders the flexibility to install the premium trigger system included in this package.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable laws. Lower receiver not included. Verify compatibility with your specific lower receiver before assembly.
