Troy Lpk 556 Blk

The Troy Lower Parts Kit 556 Black is a complete component assembly designed for builders and armorers constructing or servicing AR-platform rifles in 5.56mm/.223 Remington. This mil-spec lower parts kit includes all the trigger group and control components necessary to build or rebuild a functional lower receiver, making it an essential choice for operators who maintain their own weapons systems or prefer verified component sourcing.

The kit features Troy's Control Grip and includes trigger, hammer, trigger pin, and bolt release components—the core elements required for lower receiver assembly on mil-spec firearms. Troy's reputation in the tactical community stems from attention to dimensional tolerances and consistent performance across production runs, critical factors when assembling weapons that must function reliably across varied operational environments. The included grip provides ergonomic control without adding unnecessary weight, and all components are finished in black for corrosion resistance.

This kit is intended for experienced builders, gunsmiths, law enforcement armorers, and military personnel who understand AR-platform assembly and comply with all applicable federal and local firearms regulations. It eliminates the need to source components individually and ensures compatibility across the trigger group. Whether building a patrol rifle, training carbine, or competition platform, this lower parts kit provides a verified foundation for 5.56mm rifle assembly.

The 5.56mm cartridge remains the standard for military and law enforcement service rifles globally, offering proven ballistics, ammunition availability, and manageable recoil characteristics. Lower receiver kits compatible with this caliber are foundational components for anyone maintaining or building modern rifle systems.
