The CMC Triggers AR-15 Stripped Lower Receiver (CMC Triggers part no. CMC-AR15-LR-STRIP) is a black mil-spec lower for builders who want to assemble an AR-15 from the receiver up. CMC makes it as a forged piece and machines it from 7075-T6 aluminum to true mil-spec dimensions. That standard is what lets a lower accept the large catalog of mil-spec parts and uppers with dependable fit. It suits a new build or an upgrade of an existing rifle, and because it arrives stripped you choose every part that goes inside it.

Key Specifications

• The platform is AR-15, the most widely supported rifle pattern for aftermarket uppers and parts.
• The receiver is sold stripped, meaning it ships without the internal fire-control parts so you can build it to your own specification.
• Material is 7075-T6 aluminum, a high-strength alloy chosen for durability under repeated firing.
• Construction is a forged lower, precision machined, which gives the finished part consistent dimensions from one receiver to the next.
• Dimensions follow true mil-spec, so standard mil-spec triggers, buffer systems and uppers are meant to fit as designed.
• The finish is black, which matches the most common upper receivers and furniture.
• The action type is semi-automatic, the configuration this lower is built to support once completed.
• Caliber compatibility is multi-caliber, because the same AR-15 lower accepts uppers in many different chamberings.
• The lower is built for mil-spec lower parts, so standard parts kits fit as designed.
• Intended use is a new build or an upgrade of an existing rifle, which is the job a stripped lower is made for.
