Bushmaster XM15-CA AR-15 Lower Receiver - Stripped Lower

The Bushmaster XM15-CA stripped lower receiver provides a forged foundation built for California-compliant AR-15 configurations. Machined from 7075-T6 aluminum and finished with a Type III hard coat anodize, it delivers a durable platform with CA-specific rollmarks designed for use with a DFM or similar top-loading fixed magazine system.

Features:

• CA-specific XM15-CA rollmark
• Designed for DFM or similar top-loading fixed magazine systems
• Forged 7075-T6 aluminum construction
• Type III hard coat anodize
• Threaded for 1/4x28 receiver tension adjustment screws

The CA-specific rollmark identifies this receiver as a California-configuration component, providing the traceability appropriate for a serialized part being built into a California-compliant rifle. Forged 7075 aluminum provides the same strength-to-weight ratio and structural integrity that mil-spec AR-15 builds require regardless of magazine configuration, and the Type III hard coat anodize provides the surface hardness and corrosion resistance appropriate for regular range use and long-term storage. This stripped lower ships without internal components and requires an FFL transfer; builders should verify current California assault weapon regulations before purchase and assembly.

Bushmaster is an American rifle manufacturer known for producing a wide range of AR-15-pattern rifles and components built to mil-spec standards for civilian, law enforcement, and commercial markets.
