MRP-H 15.3 M-LOK ARCA  Upper Receiver

Ambidextrous Charging Handle, S-A Bolt Carrier Group, MARS-H DMR Lower Receiver 

Utilizing the LMT® patented Monolithic Rail Platform, MRP™.  The only true monolithic rail platform, milled from a single solid piece of aerospace aluminum forging. It utilizes two locking bolts accessible from the side of the receiver to lock in the barrel extension. This patented technology engages the barrel extension for a full 360 degrees around the extension and makes the barrel removable within seconds with a return to zero of the same barrel. One receiver can utilize numerous barrels of varying length, material, and caliber. 

Based off our 15.3" MRP-H M-LOK upper receiver, now featuring an integrated ARCA rail at the rear of the handguard.  The upper receiver has 22" of picatinny rail on the 12 o’clock position while the remaining 7 sides provide M-LOK compatible attachment points. 

MARS-H barrels utilize a low profile gas block and straight gas tube.  They possess a proprietary coating and are cryogenically treated for long term durability. 

The MARS-H ambidextrous lower receiver features LMT's EDM machined two-stage AXLE trigger, winter trigger guard, endplate with QD swivel point, Estonia grip, and DMR stock. The ambidextrous features include bolt catch and release, magazine catch, and safety selector. As with all LMT lower receivers, the extension tube is coated with dry film lubricant. This weapon system comes complete with a 20 round Magpul magazine, operator's manual, and 3 MLOK grip panels. All LMT firearms can also be purchased with select-fire configuration for use by qualified agencies.
