KIT notice as of March 1st 2020:

All build kits are subject to change slightly in this time of EXTREME demand. We are not currently able to fill specific spec requests. The kit parts will fall into the general specs above but items such as stocks, handguards, and muzzle devices are changing daily.

Due to extreme order volume, the handguard may NOT be a quad rail. It will be either a quad rail, mlok, or keymod depending on availability.  You can still attach rail sections to mlok and keymod for your accessories
