RUGER AR Lower Parts Kit with GI Trigger and A2 Grip (91002)

The Ruger Lower Parts Kit is a complete AR-pattern lower parts kit compatible with AR-pattern rifles and pistols, featuring a GI trigger group and A2 grip with all hardware needed to fully assemble a mil-spec AR lower receiver. Built by one of the nation's leading manufacturers of rugged, reliable American-made firearms, the Ruger Lower Parts Kit delivers the quality and consistency that builders and armorers expect from the Ruger name.

The Ruger Lower Parts Kit includes every component needed to fully assemble a mil-spec AR-pattern lower receiver, from the complete GI trigger group to the bolt catch, magazine catch, safety selector, and all associated pins, springs, and detents. The GI trigger group includes a standard AR trigger, hammer, disconnector, and all associated springs and pins for a familiar, mil-spec single-stage trigger pull that AR-platform shooters and builders will recognize immediately. An A2 pistol grip ships complete with grip screw, grip screw washer, and adjustment screw, eliminating the need to source grip hardware separately and ensuring a complete, ready-to-install grip assembly. For AR-platform builders, gunsmiths, and owners completing a new lower build or replacing worn components on an existing rifle or pistol, the Ruger Lower Parts Kit provides everything needed in a single purchase without hunting down individual parts.

The kit includes takedown and pivot pins with their associated springs and detents, buffer retainer and spring, trigger guard assembly and pin, bolt catch with spring, plunger, and pin, and magazine catch with button and spring, covering every lower receiver assembly need from start to finish.
