Lewis Machine & Tool’s innovation truly shines with its new CSW, or “Confined Space Weapon.”

The CSW has a 10.5-inch, integrally suppressed barrel. The 1-in-7-inch-twist barrel is actually 8.2 inches long, with the suppressor making up the remainder. The barrel, gas system and suppressor are all part of one assembly. In the case of LMT’s popular Monolithic Rail Platform (MRP), this means you can switch out the suppressed barrel unit for a standard barrel, or a different caliber suppressed barrel, if desired by loosening a bolt.

The forend of the CSW is larger—in fact, it’s the size of LMT’s .308 Winchester/7.62mm NATO handguards—to accommodate the suppressor. The handguard’s sides are slick, but rails can be added for accessories where necessary.
