Description

The Lewis Machine & Tool Company MARS-LS Stripped Lower Receiver in black is a premium, duty-grade foundation for an AR-pattern rifle build. Precision machined from forged aluminum and finished in a durable hardcoat anodizing, the M7SL lower reflects LMT’s reputation for tight tolerances and professional-grade manufacturing standards.

This MARS-LS (Modular Ambidextrous Rifle System – Lower Receiver, Semi-Automatic) design incorporates fully ambidextrous controls directly into the receiver, including mirrored bolt catch and magazine release functionality. The integrated ambidextrous architecture enhances ergonomics and operational efficiency for both right- and left-handed shooters without requiring additional aftermarket components. The flared magazine well aids in smoother reloads, while the clean machining and consistent finish deliver a refined, purpose-built appearance.

As a stripped lower receiver, the M7SL is supplied without internal fire control components, allowing for customization with compatible parts while maintaining the structural integrity and engineering standards expected from LMT. Built to professional specifications and trusted by military and law enforcement users worldwide, the LMT MARS-LS stripped lower provides a robust and adaptable starting point for a high-performance rifle platform.
