Arson Machine makes light mounts right here in the USA, Oregon to be specific. Their line includes mounts for Keymod, M-LOK, MOE Hand Guard Slots, and even a mount specific to the Beretta CX4 carbine.
The mounts are machined from 6061 aluminum with hard anodized finish. They can accept a 1″ flashlight ring or a Scout adapter for Surefire’s M300/M600 series of weapon lights. The mounts are designed to keep the lights relatively close to the rail and offset them from the mounting point.
Check out Arson Machine and keep an eye on them for future releases.
