Bolt and bolt carrier groups 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.
LM308MWS and CQB MRP Defender The Monolithic Rail Platform (MRP) was created by the company, a one-piece,
Picatinny-topped AR-15-pattern upper receiver made from a forged aluminum block. The MRP upper receiver has a quick-change barrel system. Its top rail position matches with the
M4 carbine and
KAC SR-15/SR-16 E3, for optical and sights compatibility. In late 2009, LMT introduced the .308 Modular Weapon System LM308MWS, which uses the
7.62×51mm NATO round. In February 2012, the
British Transport Police began to use AR-pattern
short-barreled rifles produced by LMT.
