Loading... Please wait...With the various rail systems currently being offered for the AR15/M16/M4 weapon system, the Vltor Low-Profile Gas Block is small enough to fit inside most rail systems. The Vltor Low-Profile Gas Block covers one-inch of the barrel's surface and is made to the tightest tolerance. These gas blocks are offered in 17-4PH stainless steel, in your choice of a matte Black Oxide or Silver (bare) finsih.
Installation and legal note: The installation of the Vltor Low-Profile Gas Block should be performed by a qualified gunsmith and/or certified armorer.

The Vltor Clamp-On gas block is probably the best low-profile gas block on the market. Its designed to be extremely strong yet tiny. It fit under my PRI Gen III handguard perfectly. I will buy another one for my next build. Thanks, Vltor.
