LWRC International, LLC, formerly known as Land Warfare Resources Corporation, is a CAGE defense contractor and firearms manufacturer.

[1] In 2006, retired U.S. Army veteran Pat Bryan, along with a management team, purchased the company and began to manufacture firearms.

[1] Darren Mellors and Jesse Gomez, employees of the previous LWRC and Grenadier, were tasked with marketing and development.

[2] The company produces several M6 series weapons based on the M4 carbine, which use a proprietary short-stroke self-regulating gas piston system and bolt carrier design.

[3] This system prevents trapped gases from contacting the bolt carrier or receiver of the weapon, which reduces the heating and carbon fouling of the internals, simplifies field maintenance, and improves reliability.
