Premium 7075-T6 Forged Aluminum Construction

The Ruger AR Stripped Lower is forged from 7075-T6 aluminum, one of the strongest and most durable aluminum alloys used in firearm manufacturing. This material provides an outstanding strength-to-weight ratio and excellent resistance to stress and impact. After the forging process, each lower is precision machined to tight tolerances, ensuring consistent quality and reliable fitment with standard AR-15 upper receivers, trigger groups, and other components. The black hardcoat anodized finish adds an extra layer of protection against corrosion, scratches, and everyday wear, helping maintain both appearance and structural integrity over time.

Mil-Spec Dimensions for Broad Compatibility

The Ruger AR Stripped Lower Receiver is manufactured to strict mil-spec dimensions. This ensures excellent compatibility with a wide range of AR-15 components from various manufacturers.

The receiver features a standard fire control pocket, magazine well, and buffer tube threads, making it suitable for both carbine and rifle-length buffer systems.
