NATO Accessory Rail

NATO Accessory Rail (STANAG 4694)

The NATO Accessory Rail (or NAR), defined by the new modernization agreement Standardization Agreement 4694, is a new standard for mounting auxiliary 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.[1]

STANAG 4694, was approved by the NATO Army Armaments Group (NAAG), Land Capability Group 1 Dismounted Soldier (LCG1-DS) on 8 May 2009. It will be forwarded to the NATO Standardization Agency and then onto individual NATO nations, which will test the NATO Accessory Rail system for final ratification.[2]

The NATO Accessory Rail is backwards-compatible with the STANAG 2324 or MIL-STD 1913 Picatinny rail, which dates back to 3 February 1995,[3] and was designed in conjunction with weapon specialists like Aimpoint, Beretta, Colt Firearms, FN Herstal and Heckler & Koch.

The Heckler & Koch G28 designated marksman rifle features NATO Accessory Rails.[4]

Technical specifications

According to the NATO Army Armaments Group the differences between the MIL-STD 1913 Picatinny rail and the STANAG 4694 are:

Another notable change is the recommendation that while in the Picatinny rail system the V-angles are used for the alignment and reference of the accessory, NATO recommends using the top surface instead.
NATO tests have shown that the Picatinny rail system does not provide good repeatability. Using the top surface as a reference and alignment of the grabbers provided excellent repeatability.

Further plans

Further plans are underway to develop a NATO standard to provide electrical power to rail mounted accessories in the future.[5] Currently, Wilcox Industries, in cooperation with Surefire, is working on the creation of a railed forend for an AR-15 that will power battery-reliant accessories such as tactical lights and laser sights. Accessories are intended to be powered by one central battery pack or via their proprietary vertical grip, the Universal Control Grip.[6]
