S-A Bolt Carrier Group | MARS-H Lower Receiver |

16″ 7.62×51 (.308) Chrome Lined 1:10″ RH Twist Barrel

This is the current flagship for the MARS-H lineup. The do-it-all MARS-H has the robustness of a combat proven weapon system, the pedigree of an accurate long range rifle, and the versatility of our MARS™ modular system. Featuring a 1/10 right hand twist, 16″, chrome lined barrel, and two stage trigger, this carbine can shoot with precision for a long time.

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.

The upper receiver has 19.25″ of picatinny rail on the 12 o’clock position.

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

The MARS-H ambidextrous lower receiver features our EDM machined two-stage trigger, winter trigger guard, endplate with QD swivel point, LMT® ergonomic textured grip, and SOPMOD 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.

    Phenomenal rifle. Miraculous price. This a beautiful unicorn of a gun, and fully built and assembled by LMT with all the bells and whistles. It’s thick, it’s heavy, and that’s just right. It came with the new lmt grip, and some extras courtesy of Big Tex, such as a magazine and most important part of all, stickers. And a never before seen MARS sticker at that! If you’re going to buy one of these, you can’t do better than Big Tex for it.
