A rail integration system (RIS; also called a rail accessory system (RAS), rail interface system, rail system, mount, base, gun rail, or simply a rail [1]) is a generic term for any standardized attachment system for mounting firearm accessories via bar-like straight brackets (i.e. "rails ...
Among scopes for rail mounts, the 22.5-degree V-shaped Zeiss rail is the most prevalent standard. It was introduced in 1990. After the patent expired in 2008, compatible scopes have been offered from manufacturers such as Blaser, [1] Leica, Minox, Meopta, Nikon, [2] Noblex (formerly Docter [3]), Schmidt & Bender [4] and Steiner.

It is similar in concept to the earlier commercial Weaver rail mount used to mount telescopic sights, but is taller and has wider slots at regular intervals along the entire length. The MIL-STD-1913 locking slot width is 0.206 in (5.23 mm). The spacing of slot centres is 0.394 in (10.01 mm) and the slot depth is 0.118 in (3.00 mm). [8]
Surveying equipment, rifle scopes, and related products are sold under the "Leupold" name, while water monitoring instrumentation, such as level and flow recorders, are marketed under the "Stevens" brand.

Many rail-grabber-mounted accessories can be used on either type of rail, and accessories designed for a Weaver system will always (SWP) fit Picatinny rails – although not vice versa because the Picatinny locking slot width is 0.206 in (5.232 mm) vs the .180 width of the Weaver, and the spacing of slot centers is 0.394 in (10.008 mm).

Some scope bases, such as Leupold & Stevens's proprietary STD mounts, use socketed bases screw-fastened to the receiver and a twistlock-like interface to secure the accompanied scope rings. An alternative design that has remained popular since the early 20th century is the dovetail rail , which is a straight metal flange with an inverted ...
