Lewis Machine & Tool Company (LMT®) was founded in 1980 to provide the US Military, Law enforcement and Government agencies with precision engineered, high quality weapons, components and modular weapon systems. Since the very beginning, LMT’s mission has been to meet, if not surpass, their customers’ expectations of quality, price and delivery of machined parts, weapon systems, assemblies and engineering services. All products are 100% USA made.
LMT continues to serve the US military, Law Enforcement and Government Agencies, and has expanded to include foreign military services. LMTs engineers design and fabricate complete weapon systems, grenade launchers, and Monolithic Rail Platform (MRP®) systems specifically for the demanding environments that the military and law enforcement face on a day-to-day basis whether in urban environments or in desert combat situations.
In response to the growing demand for quick-change barrel systems Karl Lewis, President of LMT designed the Monolithic Rail Platform. The MRP upper receiver is a one-piece lightweight upper receiver with an integral forend. Mi-Std 1913 rails run from front to the forend on each of the four sides. The MRP receiver comes in two different lengths, one traditional rifle and the other for Close Quarter Battle (CQB). With four rails, the MRP® system offers plenty of places for accessories such as optics and tactical lights.

The only true monolithic rail platform, milled from a single solid piece of aerospace aluminum forging. It utilizes two locking bolts accessible from the side of the receiver to lock in the barrel extension. This patented technology engages the barrel extension for a full 360 degrees around the extension and makes the barrel removable within seconds with a return to zero of the same barrel. One receiver can utilize numerous barrels of varying length, material, and caliber.For users who prefer the Piston Driven System, for increased reliability in any environment and climate, desert included
