LMT MARS-L 16″ 5.56 MLC MLOK Rifle


MLC Upper Receiver | Ambidextrous Charging Handle |

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

16″ 5.56×45 (.223) Chrome Lined 1:7″ RH Twist Barrel

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 14.5″ of uninterrupted 1913 picatinny rail on the 12 o’clock position. The remaining 7 sides provide M-LOK compatible attachment points.

Monolithic rail platform 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-L ambidextrous lower receiver features LMT® ergonomic textured grip and SOPMOD stock, and the ambidextrous features include bolt catch, 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 3 grip panels, one magazine and owner’s manual.

Only available for purchase through Federal Firearms Licensed Dealers.  All LMT® firearms can also be purchased with select-fire configuration for use by qualified agencies.

Barrel: 16.1″ 1:7 Twist

2 reviews for LMT MARS-L 16″ 5.56 MLC MLOK Rifle – CQBMLK16-MARS

  1. Case (verified owner)

    After some back and forth with Sol on this one, I impulsively bought this rifle and don’t regret it one bit. Shooting sub-MOA with poor-mans match ammo (IMI RazorCore) out to 300 meters (as far as I wanted to go for group shooting), and easily ringing steel out to 500 meters. My 800 meter range had some steel plates at 800, and this rifle hit that 5 out of 8 times, with the misses likely being bad wind calls on my part. As is usually the case, Sol’s customer service remains the gold standard with online shopping, and he will continue to get my business as he has been.

    Just picked this up. Outstanding price and quick shipping. It was east to get everything processed with my FFL and the rifle was perfect. Rooftop absolutely has my business going forward.
