LMT MARS-L MRP 5.56x45 NATO Rifle 16" Barrel - 30 Rd

Step into the pinnacle of tactical superiority with the LMT MARS-L MRP 16" 5.56 NATO Rifle. Engineered for operators who refuse to compromise, this platform seamlessly blends unmatched durability with cutting-edge versatility. At its core is Lewis Machine & Tool’s patented Monolithic Rail Platform (MRP)—a single, solid piece of forged aerospace aluminum that provides absolute structural rigidity and an uninterrupted 18.5-inch 12 o'clock Picatinny rail. This allows for zero-shift optic mounting while the 7-sided M-LOK profile keeps the front end slim and fully customizable.

Coupled with the legendary MARS-L fully ambidextrous lower receiver, this rifle guarantees seamless operation, rapid reloads, and intuitive control from either shoulder. The 16-inch chrome-lined, cryogenically treated barrel features LMT’s ingenious quick-change system, letting you swap barrel lengths or calibers in seconds while retaining dead-on zero. Finished off with LMT's highly sought-after SOPMOD stock, this rifle delivers elite, battle-proven performance for professional duty, home defense, and competitive shooting alike.
