One of VLTOR's most innovative products is the Versatile Interface Structure (VIS) upper receiver assembly. The VIS is a polylithic upper receiver assembly that ties the normally individual receiver and handguard into a single, aggregate part. This combination overcomes many problems that are associated with the traditional "two piece" design; most notably the greatly improved structural strength and repeatable accuracy. This affords the user all the benefits of a free-floating barrel and solid railed forend. Note: The VIS comes supplied with the stripped upper only. The barrel, sights, and all other accessories must be purchased separately. • Aircraft-grade aluminum construction • Hardened to T6 specifications • Hard coat anodized, black per MIL-A-8625 TYPE III Class 2 • 6013 forged upper with 6061 extruded handguard • Polylithic design • Handguard length rails on each side • Removable lower handguard • M203 barrel mounting compatible • Compatible with all Mil-Spec AR-15 parts and accessories • Available with shell deflector (VIS-SK) and forward assist or shell deflector only (VIS-AK)
