LMT Defense MARS L Stripped Lower, Multi-Caliber, Black

Elevate your AR-15 build with the LMT MARS-L Stripped Lower Receiver, a premium foundation engineered for true ambidextrous operation and exceptional durability. Forged from high-strength 7075-T6 aluminum with a hardcoat anodized finish, this lower features fully integrated ambidextrous controls—including selector, magazine release, and bolt catch/release—machined directly into the receiver for seamless use by left- or right-handed shooters. The enhanced flared magazine well accelerates reloads, while precise Mil-Spec tolerances guarantee perfect compatibility with standard AR-15 upper receivers and lower parts kits, making it an ideal choice for custom rifles in 5.56 NATO, .300 Blackout, or other calibers.

Its robust construction reflects LMT's military-grade standards, providing a lightweight yet solid platform that supports professional, duty, competition, or personal defense configurations. This stripped receiver arrives ready for your preferred trigger group, grip, stock, and other components to create a personalized, high-performance rifle.
