The distinctive crimson red finish adds a custom appearance that stands out while maintaining dependable function for competition, range, and recreational shooting.
Lite Lower Parts Kit
Designed specifically for builders planning to install an aftermarket trigger, the Lite Lower Parts Kit includes every essential lower receiver component except the factory fire control group. This eliminates unnecessary duplicate parts while maintaining full Mil-Spec compatibility. The kit includes a black A2 pistol grip, selector assembly, magazine catch, bolt catch, takedown and pivot pins, trigger guard, springs, detents, and installation hardware needed to complete a stripped lower receiver around your upgraded trigger.
Mil-Spec Anti-Walk Pin Set
The included steel anti-walk pin set replaces traditional hammer and trigger pins with a more secure retention system designed to prevent lateral movement during operation. Manufactured from steel with a durable black nitride finish, the .154" Mil-Spec pins help reduce receiver wear while maintaining proper trigger alignment during high round-count shooting. Installation hardware, hammer and trigger posts, hex keys, and an installation guide are included for straightforward assembly.
Follow safe handling and manufacturer instructions. Ensure compliance with all applicable laws. Verify compatibility with your specific lower receiver before installation. Use quality ammunition and maintain proper firearm maintenance.
