The LMT Defense MARS-L lower receiver offers ambidextrous controls to include: selector, magazine release and bolt catch and release. The ambidextrous magazine and bolt catch mechanisms are machined directly into the receiver and have been designed to function as ergonomically as possible.
This stripped version comes with the ambidextrous components installed. Save time and money with our MARS specific lower parts kit containing all the parts you need and none of the parts you don't.
The patented LMT Monolithic Rail Platform (MRP) upper receiver is the only AR-15 upper that incorporates the handguard and receiver as one component. This state-of-the-art design is CNC machined from a single piece of forged aerospace aluminum resulting in benefits and functionality unmatched in the industry. Integrating this upper receiver with an MRP barrel creates an incredibly simplistic modular platform in which the barrel is held in place with a proprietary locking system utilizing two locking bolts on the right side of the receiver. Barrel swaps and caliber changes are easily completed in a few minutes with only a T-30 Torx bit and torque wrench (a factory pre-set torque wrench is available). Additionally, since the handguard is integral to the receiver you will not experience shifts in point of impact while using aiming devices that are attached directly to the handguard. Nor will you need to purchase expensive cantilever optic mounts. This receiver utilizes the patented LMT MRP barrels and like the other rile length MRP receivers, is designed for use with their direct impingement barrels in lengths from 14.5" to 20".
Buy with confidence knowing that your LMT Factory Cerakote parts are covered by the LMT Factory Warranty.
These parts are Hardcoat Anodized black, very lightly blasted to properly prepare the surface for Cerakote and painted to perfection. They are then laser engraved, color filled (selector position - lowers) and assembled.
