Lewis Machine & Tool welcomes the revolutionary Confined Space Weapon to its arsenal. LMT® built the CSW300 with its patented Monolithic Rail Platform, the only true monolithic rail platform, which is milled from a single high-grade aluminum forging. Two locking bolts on the side of the receiver lock the barrel extension in place. MRP technology engages the barrel extension for a full 360 degrees and allows the barrel to be removed in seconds while minimizing point of impact shift. One receiver can support numerous barrels of varying length, material, and caliber. The Confined Space Weapon measures 24″ collapsed and is ideal for close quarter combat operations. The weapon is rapidly growing in popularity with government and military groups around the world.
CSW300 Wide LM8 Upper Receiver | Ambidextrous Charging Handle |
S-A Bolt Carrier Group | MARS-L PDW Lower Receiver |
The CSW300 upper receiver is mid-length and designed to enclose its combined barrel and suppressor. The receiver has an 16.5-inch Picatinny top rail while the remaining sides have locating lugs and screw holes. The locating lugs reduce recoil of attached accessories while the screw holes hold the accessory or rail to the weapon. This system comes with a grip stop installed on the front end to reinforce safe hand placement.
The barrel uses LMT’s Virtual Baffle System technology in its integral suppressor. The VBS suppressor defeats its competitors in the following ways:
- passes SOCOM’s SURG high-performance stress test
- rated for automatic fire
- minimizes cyclic rate increase
- maintains a lower average surface temperature at one hundred rounds
- minimizes point of impact shift.
Consequently, it is one of the most efficient and user-friendly suppressors on the market.
The MARS®-L ambidextrous lower receiver features our EDM machined two-stage trigger, winter trigger guard, endplate with QD swivel point, LMT® ergonomic textured grip, and shorty SOPMOD stock. The ambidextrous features include bolt catch and release, magazine catch, and safety selector. As with all LMT® lower receivers, the extension tube is coated with dry film lubricant.
This weapon system comes with grip stop, six grip panels, one magazine, and owner’s manual.
