Sons of Liberty Gun Works Castle Nut with Class 3A Thread SOLGW-CASTLENUT

The Sons of Liberty Gun Works Enhanced Blaster Guts is a comprehensive lower parts kit (LPK) designed to provide a high-quality foundation for a custom AR-15 build. This "Enhanced" version is built around the Liberty L2S 2-Stage Trigger, which features a hybrid straight/curved "Liberty Bow" and a 4.5 lb total pull weight. The kit includes professional-grade components like the B5 Systems P-Grip 23 for improved ergonomics and a mil-spec ambidextrous safety selector for versatile handling. Every small part is sourced to exceed standard mil-spec requirements, such as KNS Precision hardened stainless steel detents and AISI 8620 steel investment cast bolt catches.
