Lewis Machine & Tool (LMT), based in Milan, Illinois, is a manufacturer of defense-grade firearms supplying militaries and law-enforcement agencies around the world. The company is known for engineering innovations like its monolithic upper receiver — which integrates the rail and upper into a single piece for rigidity — and the quick-change barrel system that lets users swap barrels and calibers.
LMT's rifles, including the R-series and the MARS (Modular Ambidextrous Rifle System) lowers, are built to military specifications and have been adopted by armed forces internationally. The brand's reputation rests on durability, precision, and the kind of hard-use reliability that defense contracts demand, all of which carry into its commercial offerings.
For shooters who want a rifle built to genuine military standards, LMT delivers professional-grade engineering and proven battlefield pedigree.
