The KeyMod system, originally developed by VLTOR, 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 different manufactures’ accessories. VLTOR is proud to now offer the KeyMod system on their rifle line, as well as their CASV handguard and VIS upper line. The company is also currently in development for a series of KeyMod accessories.
