Machined from 7075-T6 aluminum, the same material used in mil-spec and premium AR-15 lowers, and finished with black anodizing for corrosion resistance and a clean, professional appearance, the Milsport lower provides a solid, consistent foundation for any build configuration. The .223 Rem roll mark clearly identifies the receiver's caliber designation for .223 Remington and 5.56 NATO compatible builds, and standard mil-spec dimensions ensure compatibility with any lower parts kit, buffer tube, and upper receiver combination on the market. This lower ships stripped, without a lower parts kit, buffer tube, stock, or trigger group, giving builders full control over the components they pair with it.

American Tactical Imports is a recognized name in affordable, reliable AR-platform components and firearms, backing the Milsport lower with the manufacturer's standard warranty.
