ATI MilSport AR-15 Stripped Lower Receiver - Cosmetic Blem

Full ATI MilSport quality at a cosmetic blem price — the starting point for your next AR-15 build. The ATI MilSport Stripped Lower is machined from 7075-T6 aluminum with a black matte anodized finish and a multi-caliber marking. Cosmetic blems are fully functional — any imperfections are visual only and do not affect fit, function, or dimensional conformance.

The ATI MilSport AR-15 Stripped Lower Receiver is a 7075-T6 aluminum, black matte anodized, multi-caliber stripped lower receiver sold as a cosmetic blem, ships without internal components, and requires FFL transfer.

Three features make the MilSport blem a practical build foundation. 7075-T6 aluminum provides the strength-to-weight ratio and structural integrity that mil-spec AR-15 builds require across any chambering. The multi-caliber marking keeps the lower unrestricted to any single cartridge, giving builders the flexibility to configure it across the full range of AR-15-compatible calibers. Cosmetic blem status means ATI has inspected the receiver for dimensional and functional conformance — only visual imperfections are present, making this a fully capable build foundation at a reduced price.

Compatible with mil-spec AR-15 upper receivers, lower parts kits, buffer systems, and furniture. Stripped — ships without internal components. FFL transfer required.
