Vltor VIS-KM12 - Keymod Upper Receiver


One of VLTOR’s most innovative products is the Versatile Interface Structure (VIS) upper receiver assembly.  VLTOR is now introducing the VIS-KM, with the integrated KeyMod system. The KeyMod system breaks from the traditional fixed quad rail setup and allows the operator to decide where accessories or rails are mounted.  KeyMod also allows for modularity between various manufacturer’s accessories. 

The VIS-KM12 upper is forged from 6061-T6 aircraft aluminum, while the keymod handguard portion is extruded from 6061.  The KM12 is hard coat anodized black, per MIL-A-8625 TYPE III Class 2, has a removable handguard, is compatible with the M203 as well as most milspec AR-15 parts and keymod accessories.  It weighs 22.4oz, has an overall length of 19.871 inches, a handguard length of 12.88 inches, and an interior diameter of 1.125 inches.
