A rail system mounted on top of a SIG SG 550 A dovetail rail on a rifle receiver for mounting a sight. 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 ...
NATO Accessory Rail (STANAG 4694) The NATO Accessory Rail (NAR), defined by NATO Standardization Agreement (STANAG) 4694, is a rail interface system standard for mounting accessory equipment such as telescopic sights, tactical lights, laser aiming modules, night vision devices, reflex sights, foregrips, bipods and bayonets to small arms such as rifles and pistols.
Passenger rail transport over many routes across European countries is facilitated through Interrail (for travelers from Europe) and Eurail (for non-European travelers) rail passes. Due to differences in railway electrification between certain countries, either multi-system electric multiple units (EMUs) or, in case of push-pull trains , multi ...
The 1913 rail (MIL-STD-1913 rail) is an American rail integration system designed by Richard Swan [1] that provides a mounting platform for firearm accessories. It forms part of the NATO standard STANAG 2324 rail. It was originally used for mounting of telescopic sights atop the receivers of larger caliber rifles.
A more modern way to accessorize the K2 and K1 is to mount a now (limited) standard issue PVS-4K Rail Integration System. It consists of an aluminum body with a long, uninterrupted rail for optical/red-dot and night-vision sights and three other rails located on the bottom and both sides. The rails are of the Picatinny-type.
An ETR 500 train running on the Florence–Rome high-speed line near Arezzo, Italy, the first high-speed railway opened in Europe. [6] The earliest high-speed rail line built in Europe was the Italian "Direttissima", the Florence–Rome high-speed railway 254 km (158 mi) in 1977. The top speed on the line was 250 km/h (160 mph), giving an end ...
Armoured trains, like this Slovak example, are one form of military use of railways. The military use of railways derives from their ability to move troops or materiel rapidly and, less usually, on their use as a platform for military systems, like very large railroad guns and armoured trains, in their own right.
This new version of K1 is known as the K1A and its production began in 1982. All K1 submachine guns in service were subsequently modified to the K1A standard. Two variants of RIS rails developed for the K1A by MITS Precision. The K1A is often mated with the PVS-4K rail integration system created by Dong In Optical (DI Optical). It is seen as a ...
