The AR-2 "Pitbull" rifle family was originally proposed in 1996 alongside the original Doberman battle rifle, as a replacement to the AKS-74u carbine. The rifle was proposed in either 5.45x39mm ComBloc or 5.56x45mm NATO, the latter of which had been flooded into Western Russia during the Battle of the Ascension. The 5.56mm cartridge was selected, in order to appeal to NATO leaders in an attempt to secure much wider support - such as the rebuilding of infrastructure lost in the war.
The Mod 0 AR-2 was put into service with a folding metal tube stock and ten inch barrel, using a direct impingement action, in 1998 as the SpV-8 (Special-purpose rifle of year (9)8). Other military nomenclature includes the SMA-5.56 (Special-purpose small assault rifle, calibre 5.56mm).

The Mod 0 was shortly retired by the introduction of the Mod 1 Doberman's Carbine variant in 2009 (though the Doberman Mod 1 Carbine had been designed in 2004), until the Mod 1 Pitbull was launched in 2013 and replaced the Doberman Carbine with its large cartridge, short barrel and high weight. During this time, the only domestic user of the Pitbull was the Samozniy People's Army Youth Corps. The Mod 1 was essentially a rebuild of the original Mod 0, offering a more substantial rail interface for optics, and improved lightness due to a higher use of composite materials in the construction, making the ten-inch barrel AR-2 barely heavier than the 8.3" barrel AKS-74u, whilst also switching from the 5.56mm cartridge to the 5.45x45mm Samozniy cartridge. in 2014, the Mod 1 family was expanded to include an 18-inch 'heavy barrelled' weapon that could be used by the Youth Corps as a light machine gun automatic rifle (featuring a short-stroke gas piston operation, rather than the direct impingement mechanism). The Mod 2 family was a slight cosmetic re-working intended for export.

The Mod 3 family sought to bring a greatly improved weapon system over the Mod 1 variant. A polymer-heavy construction, inspired by the Mod 2 and Mod 3 Pitbulls, combined with an improved modularity such as multi-calibre capability, as is being displayed here with a 7.62x39mm magazine well, and also a 7.62mm barrel replacement on the 16" short-stroke variant.

Very nice, I like how it's based upon the SIG variants.
