CMMG AR-15 A1 Receiver Extension and Stock Kit

The CMMG AR-15 A1 Receiver Extension and Stock Kit provides the components needed to equip a compatible AR-15 lower receiver with a traditional rifle-length fixed stock system. Modeled after the classic A1 configuration, this kit combines a fixed polymer stock with the matching rifle receiver extension, buffer, and action spring.

The A1-style stock features durable polymer construction with a rear storage compartment for carrying small accessories or maintenance items. An integral sling mount adds a convenient attachment point while maintaining the traditional fixed-stock profile.

Unlike carbine buffer systems that use an adjustable receiver extension, this kit is designed around a rifle-length recoil system. The included CMMG A1 receiver extension, rifle buffer, and rifle action spring provide the matched components needed for a complete fixed-stock installation.
