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 carbine length MRP receivers, is designed for use with
either their piston barrels or direct impingement barrels in lengths from
14.5" to 20".
THESE UPPERS ARE PULLED FROM COMPLETE FACTORY BUILT RIFLES AND HAVE BEEN ADJUSTED TO FIT MARS-L LOWER RECEIVERS. IF YOU HAVE ANY QUESTIONS, PLEASE CONTACT US PRIOR TO ORDERING.
