Ruger AR-15 Lower Receiver - Stripped Lower

The Ruger AR stripped lower receiver provides a flexible foundation for an AR-15 build in any compatible chambering. Forged from 7075-T6 aluminum with a multi-caliber marking, it delivers a strong, precise platform without caliber-specific rollmark restrictions.

Features:

• Forged 7075-T6 aluminum construction
• Multi-caliber marking
• Black finish
• Compatible with standard mil-spec lower parts kits
• Made in the USA

Forged 7075-T6 aluminum provides the grain structure and strength-to-weight ratio that forged lowers offer over billet alternatives, meeting mil-spec structural requirements across any chambering a builder chooses. The multi-caliber marking keeps the lower unrestricted to a single cartridge, the right choice for anyone who plans to swap uppers across calibers or wants maximum configuration flexibility from a single serialized receiver. Standard mil-spec geometry ensures compatibility with the full range of lower parts kits, triggers, buffer systems, and upper receivers on the market. As a serialized receiver, purchase requires an FFL transfer, and it's backed by Ruger's standard manufacturer warranty.
