lwrc m6

The M6 is a series of carbines designed and manufactured by LWRC International. It is based on the M4 carbine, with which it shares 80% of its parts. The 'M' model name is not a US military designation. Like the HK416, it features a proprietary short-stroke self-regulating gas piston system and bolt carrier/carrier key design, which prevents trapped gases from contacting the bolt carrier or receiver of the weapon. The manufacturer claims that this reduces the heating and carbon fouling of the internals, simplifies field maintenance, and improves reliability.Standard length barrel is 16.1 in, with a 1:7″ twist (six lands, right twist) barrel with a ferritic nitrocarburized surface conversion which covers the barrel, inside and out, as well as the piston components. Barrel lengths of 10.5″, 12.7″, 14.7″ and 18″ (available for select models) are available.
