Ruger AR Lower Parts Kit GI Trigger

Complete an AR-15 lower receiver build or keep essential replacement parts on hand with the Ruger AR-15 Lower Parts Spring and Pin Kit. Built to Ruger’s standards for rugged reliability, this kit includes many of the small springs, pins, detents, and retainers commonly needed during lower receiver assembly, maintenance, or repair. The kit includes hammer, disconnector, trigger, magazine catch, bolt catch, takedown, buffer retainer, and ejector-related components, along with trigger pins, a bolt catch plunger and pin, a safety selector detent, and a trigger guard pin. It is a practical choice for AR-15 builders, armorers, and shooters who want factory Ruger replacement components available at the workbench or in a spare-parts kit. These components are intended for AR-15-pattern firearms, but compatibility can vary due to differences among manufacturers and individual firearm configurations. Ruger does not guarantee fit or performance in every platform. Installation by a qualified gunsmith is recommended to ensure proper function and safety.
