Overview

The Sons of Liberty Gun Works Blaster Guts Complete Lower Parts Kit represents a significant upgrade over standard mil-spec components, featuring their acclaimed Liberty Fighting Trigger and premium materials throughout. SOLGW has reimagined every component in the lower parts kit, using superior materials and manufacturing processes to exceed USGI TDP specifications.

The Liberty Fighting Trigger delivers an ultrareliable 6 lb pull weight with a grit-free break that rivals premium drop-in triggers. The trigger and hammer are treated with Nickel PTFE coating to reduce friction and maintain lubricity over thousands of rounds. Critical components like the bolt catch are cast from AISI 8620 steel per USGI TDP, while takedown and selector detents are upgraded to hardened stainless steel from KNS Precision for enhanced durability.

This kit elevates the AR-15 platform with components engineered for serious use. The steel magazine release button replaces the commonly used aluminum version for long-term reliability. Every pin, spring, and detent has been carefully selected to create the perfect balance between mil-spec reliability and enhanced performance, making this the ideal foundation for duty, competition, or defensive rifles.
