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.

1. A top opening, modular top rail, multi-rifle adaptable free float rail accessory system (RAS) for use with a firearm having a receiver, a barrel, and a barrel nut which secures the barrel to the receiver, the RAS comprising: a top portion having longitudinally extending lower, edges with a plurality of recesses spaced apart along said edges;a bottom portion having a rearward end machined to receive a bottom part of the barrel nut, a forward face with receptacles formed therein, and longitudinally extending upper edges, each edge having a groove with longitudinally spaced openings therein;a plurality of pins received in said openings and oriented to removably engage with said plurality of recesses located on said top portion when the top portion is mounted to the bottom portion, said top portion being translatable in one of a forward direction or rearward direction relative to the bottom portion to position the pins within said recesses to mount the top portion to the bottom portion;a clamp assembly having a top piece with a center portion having an inner surface configured to receive a top part of the barrel nut and an outer portion configured to secure the clamp assembly to the rearward end of the said bottom portion; anda plurality of screws configured to removably secure said top portion to said bottom portion, said screws being received within said receptacles in the forward face and extending in a direction parallel with a longitudinal axis of said bottom portion, said screws having heads configured to enable said screws to be threadedly secured to the bottom portion manually by a user without the aid of tools. 2. The RAS as set forth in claim 1, further comprising o-rings placed between the screw heads and the forward face to facilitate manual tightening of the screws and prevent unintentional backing out of the screws as a result of vibration of the firearm. 3. The RAS as set forth in claim 1, wherein the heads of said screws have a textured outer surface and are of sufficient size to enable the end user to manually grasp and rotate the screws without difficulty. 4. The RAS as set forth in claim 1, wherein said firearm includes a gas piston operating system that is accessible for cleaning and maintenance when the top portion is removed without having to remove the gas block of the firearm. 5. The RAS as set forth in claim 1 wherein said recesses are J-shaped. 6. The RAS as set forth in claim 1, further comprising an anti-rotational device having an inner surface configured to receive said barrel nut, two rearwardly directed flanges on opposite sides of the firearm receiver, and a front edge, said front edge abutting a flanged end of said barrel nut when the clamp assembly is secured to the rearward end of the bottom portion, said flanges preventing rotational movement of the RAS. 7. A top opening, modular top rail, multi-rifle adaptable free float rail accessory system (RAS) for use with a firearm having a receiver, a barrel, a barrel nut which secures the barrel to the receiver, and a gas piston operating system, the RAS comprising: a top portion having longitudinally extending lower edges with a plurality of J-shaped recesses spaced apart along said edges;a bottom portion having a rearward end machined to receive a bottom part of the barrel nut, a forward face, and longitudinally extending upper edges, each edge having a groove with longitudinally spaced openings therein;a plurality of pins received in said openings and oriented to removably engage with said plurality of J-shaped recesses located on said top portion when the top portion is mounted to the bottom portion, said top portion being translatable in one of a forward direction or rearward direction relative to the bottom portion to position the pins within said J-shaped recesses;a clamp assembly having a top piece with a center portion having an inner surface configured to receive a top part of the barrel nut and an outer portion configured to secure the clamp assembly to the rearward end of the said bottom portion; anda component mounted on the front face to removably secure the top portion to the bottom portion, said component having an outer part configured to enable the end user to manually manipulate and tighten and loosen said component to secure and unsecure the top portion to the bottom portion, respectively, without a tool. 8. The RAS as set forth in claim 7, wherein said component includes a plurality of pusher screws received within receptacles formed in said front face, said screws extending parallel with a longitudinal axis of said bottom portion when received within said receptacles. 9. The RAS as set forth in claim 8, wherein said screws have heads with a textured outer surface and further comprising o-rings placed between the screw heads and the forward face to facilitate manual tightening of the screws and prevent unintentional backing out of the screws as a result of vibration of the firearm. 10. The RAS as set forth in claim 9, wherein said top portion includes receptacles for receiving tip portions of said pusher screws, said pusher screw tips thereby being seated against said top portion when tightened.
