American Tactical Mil-Spec AR-15 Stripped Lower Receiver, Multi-Caliber

The American Tactical Mil-Spec AR-15 Stripped Lower Receiver (brand part no. GLOWMS) is the serialized firearm component of an AR-15 build, machined from forged aluminum to mil-spec dimensions. American Tactical builds this lower to accept standard mil-spec AR-15 parts kits and is compatible across multiple AR calibers, giving builders a solid foundation to complete with the upper, trigger group, and furniture of their choice. Among AR-platform rifles in the AR rifles category, this stripped lower favors builders assembling a custom AR-15 from the receiver up.
