The new Vltor Lower Receiver Assembley is machined from a 7075 forging, it is marked with the well known Vltor "V" and Gladius on the right side of the magazine well. The Vltor lower receiver also features unique grip enhancing cuts on the front of the magazine well, an oversized mag release button and the Vltor "side saddle" sling plate - featuring three positions to mount a quick disconnect sling swivel. The lower receiver comes complete with a Vltor receiver extension tube, standard carbine buffer, spring and A2 grip.

This SBR has a 7in Barrel and Vltor Flash Hider mounted with a Vltor CASV-M Handguard.

The CASV-M was originally designed for the popular mid-length gas system rifles. Like all CASV systems, the CASV-M relies on piggy-back mounting to the top of a flat-top M4 or M16A4 upper receiver. This chassis features a removable lower handguard, which allows the access of an M203 grenade launcher. The smooth body construction allows multiple rail mounting points, adaptable to any mission needs. The area forward of the top rail can be filled with a short rail, or used to mount the VLTOR flip-up sight assembly. This forearm allows plenty of space for modular accessories and adequate grip without sacrificing any of its lightweight characteristics.
