An improved Rail Adaptor System / Rail Accessory System (RAS) which attaches to a firearm. The rail is top opening, modular, and free floats the barrel. Provided is a rigid, lightweight, strong platform for mounting firearm accessories. Heat transmission from the barrel assembly to the user is limited. The user is also protected from ventilated gases originating from the operating system. A quick detachable top rail section is provided so that that gas system may be easily accessed. This removable top section of the rail is what makes this device unique because the RAS may be installed without removing the barrel, gas system, front sight base, flash hider or the barrel nut. The herein described RAS is adaptable to a wide variety of firearms with the use of conversion parts. The top rail “returns to zero” on reinstallation allowing the remounting of various optics and electronic gun sites without the need to realign them.

Height and length are adjustable at several points. There is a special type of vise for holding the gunstock. As usual, the vise bolt pulls the movable plate toward the fixed one but, like some of the vise's predecessors, traces out an arc at the top, pivoting from the bottom as the bolt, situated just above the pivot, is turned. Within the movable plate a special cylinder is situated which gives and turns freely in response to the bolt's advance and withdrawal in passing through a threaded tunnel within it. This action prevents the biting down or binding upon the bolt which would otherwise occur because of the plate's pivoted travel as the bolt is advanced or withdrawn. The support's framework, best made from economical tubular bar-stock, is adjustable for leveling and leaning corrections and include anchoring blocks within the structure through which leveling bolts pass.
