LMT 16″ CQB Monolithic MARS 5.56 mm Rifle – M-LOK

Gas operated MARS Ambi with barrel swap capability

The LMT MARS MRP is quite possibly one of the best AR platform rifles on the market.  We like to say that there are two types of AR enthusiasts in the World:  Those who know LMT and those who do not.  LMT is not a household name in the AR business, and most of their production goes to domestic and foreign armies, so if you have not heard of LMT, you are simply one of those who needs to.  LMT builds battle rifles.  In the process, you happen to get some of the best features made, like a full ambidextrous lower and an upper receiver that is monolithic with the upper receiver, and a barrel swap mechanism that is the best.  While this Rifle comes to you as with a 16″ 5.56 NATO barrel, you can buy a shorter 5.56mm barrel for maneuverability or a longer 20″ barrel built for match accuracy.  Or, you can swap to a .300 Black Out or 6.8 SPC, or have a 6mm ARC barrel made for you!

LMT Defense MARS-L semi automatic rifle chambered in 5.56NATO. This rifle features a 16-inch chrome lined barrel with 1:7 RH twist, uninterrupted full Picatinny rail on the upper receiver, with M-LOK attachment points on the remaining sides.

The Monolithic Rail Platform barrels utilize a low profile gas block and a straight gas tube. 

The MARS-L ambidextrous lower features  EDM machined two-stage trigger, winter trigger guard, end plate with QD swivel point, LMT ergonomic textured grip, and a SOPMOD stock. The The ambidextrous features include bolt catch and release, magazine catch, and safety selector. 

This weapon is built with the LMT patented Monolithic Rail Platform, MRP, in M-LOK. 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.
