Lewis Machine & Tool Company (LMT) is an American armaments company founded by Karl R. Lewis, in 1980. It manufactures weapon systems, including a variant of the M4 carbine and the M203 grenade launcher.[1] Its products are used by the military forces of the United Kingdom, New Zealand, Estonia, Switzerland, Lebanon and the United States. It formerly produced forged FN FAL receivers for Illinois-based DS Arms. The company founder has several arms related inventions assigned to him.[2]

LMT does business as LMT Defense.[3]

History

[edit | edit source]

LMT was established by Karl Lewis in 1980 from Milan, Illinois in order to manufacture firearm components.[4] In 1986, LMT began to manufacture small arms for overseas sale.[4]

Bolt and bolt carrier groups

[edit | edit source]

A patented AR-15-pattern is produced with a bolt design featuring a redesigned extractor intended to improve the extraction of cartridges under adverse conditions. The company also produces a redesigned bolt carrier intended to improve the reliable performance of the rifle's “internal piston” system by obtaining a similar timing sequence with 14.5-inch carbine-length barrels compared to 20-inch rifle-length barrels for AR-15-pattern arms.[5]

LM308MWS and CQB MRP Defender

[edit | edit source]

The Monolithic Rail Platform (MRP)[6] was created by the company, a one-piece, Picatinny-topped AR-15-pattern upper receiver made from a forged aluminum block.[7] The MRP upper receiver has a quick-change barrel system.[8] Its top rail position matches with the M4 carbine and KAC SR-15/SR-16 E3, for optical and sights compatibility.[9]

In late 2009, LMT introduced the .308 Modular Weapon System LM308MWS, which uses the 7.62×51mm NATO round.[10]

In February 2012, the British Transport Police began to use AR-pattern short-barreled rifles produced by LMT.[11][12][13]
