Bushmaster XM15-CA AR-15 Stripped Lower Receiver

A Bushmaster forged lower built for California-compliant AR-15 configurations. The Bushmaster XM15-CA Stripped Lower Receiver is machined from forged 7075-T6 aluminum with a Type III hard coat anodize finish and CA-specific rollmarks, designed for use with a DFM (Detachable Fixed Magazine) or similar top-loading fixed magazine system required for California-compliant featureless and fixed-magazine builds.

The Bushmaster XM15-CA Stripped Lower Receiver is a forged 7075 aluminum AR-15 lower receiver marked 'XM15-CA' with a Type III hard coat anodize finish, designed specifically for California-compliant AR-15 builds requiring a fixed or top-loading detachable magazine system.

Three features define the XM15-CA's role as a California-compliant build foundation. The CA-specific XM15-CA rollmark identifies this receiver as a California-configuration receiver, providing the traceability and documentation appropriate for a serialized component being built into a California-compliant rifle. Forged 7075 aluminum provides the strength-to-weight ratio and structural integrity that mil-spec AR-15 builds require regardless of magazine configuration — the California compliance requirement does not change the performance standard for the lower receiver itself. Type III hard coat anodize finish provides the surface hardness and corrosion resistance appropriate for a receiver that will experience regular range use and storage across its service life.

Designed for use with DFM or similar top-loading fixed magazine systems in California-compliant AR-15 builds. Stripped — ships without internal components. FFL transfer required.
