LMT

What LMT does

LMT Defense (legal name Lewis Machine & Tool Co.) is a privately held U.S. firearms manufacturer founded in 1980 by Karl Lewis and headquartered in Eldridge, Iowa. The company designs and builds military-grade small arms and weapons accessories, with a product portfolio anchored by the patented Monolithic Rail Platform (MRP) — a true monolithic upper receiver milled from a single aerospace aluminum forging — and the Modular Ambidextrous Rifle System (MARS) family, which provides full ambidextrous controls. Additional product lines include the MWS (Modular Weapon System, AR-10/SR-25 pattern), Defender entry-level rifles, Standard Patrol Models, and military grenade launchers, plus a broad aftermarket parts catalog of barrels, bolt carrier groups, triggers, and upper/lower receivers. Suppressors are sold through the sister company LMT Advanced Technologies (LMT-AT) under the ION and LINK brands.

LMT's go-to-market is split between direct government/military procurement (tender and contract-based sales to U.S. SOCOM, U.S. Army, and allied armed forces) and FFL-only dealer distribution for law enforcement and qualified commercial buyers. Revenue is generated almost entirely from hardware sales of complete rifles and components, with a small licensing stream exemplified by the November 2025 license agreement with Northrop Grumman to produce the 7.62mm Bushmaster Chain Gun. Major recent contract wins include the $92M-ceiling SOCOM MRGG-A award in 6.5mm Creedmoor (August 2025), the Swiss Armed Forces Sturmgewehr 25 contract (February 2025), continued Royal Moroccan Army support (August 2024), and a U.S. Army grenade launcher contract (March 2021). The customer base spans U.S., U.K., Estonian, Swiss, New Zealand, Jordanian, Moroccan, and Chilean armed forces, with products sold under ITAR/EAR export controls and distributed through Federal Firearms Licensed Dealers.
