If you're looking for a competitively priced, modular rail, free floating handguard, then Vltor has the answer. The battle proven CASV bolts directly to any standard flattop upper receiver, and gives users an improved mounting solution for additional accessories.
This "piggy-back" mounted handguard system has a removable lower handguard which allows the mounting of flare launchers and other aftermarket accessories. At this time, we offer only the extended length model which was specifically developed to fit the M4 carbine or the CQB (10.3-inch barrel) configured flat top upper receiver assembly. The CASV-EL was designed and manufactured solely for the US Navy. After fulfilling the Navy contracts, Vltor began offering this system to the civilian sector.
This CASV chassis is made entirely of aluminum with exception to the stainless steel mounting hardware. After mounted, the CASV adds less than 1lb to the firearm's overall weight.
