We haven't found ten different manufacturers utilizing a KeyMod system for their handguard. They will be releasing a .308 and .223 version. Apparently, they didn't tell anyone else that they would have this ready as the only exclusive offering.
The RKM KeyMod Handguard will be available on its own along with full production CMMG rifles for both calibers. A proprietary barrel nut will be provided with the rail and allow for quick and simple installation. Expect the new RKM along with rifles to be released this Summer.
