Overview

The LMT MARS-L CQB MRP 10.5" is a MARS-L/MRP short-barrel configuration built on LMT's monolithic upper. Core specs from LMT's MARS-L spec sheet and manual: 10.5-inch 5.56/.223 barrel, 1:7 twist, carbine upper compatibility, monolithic quick-change-barrel architecture, and 6.47 lb weapon weight with SOPMOD-stock dimensions.

The monolithic upper anchors the barrel to the same receiver, so a torque wrench and LMT barrel hardware let owners swap barrels and calibers. The shorter gas system and 1/2x28 muzzle threads make it a credible suppressor host. Stock style, rail style, and exact MSRP vary by SKU, so confirm the specifics of the exact LMT or dealer listing.
