The AK-105 is a short barrel, carbine version of the AK-74M rifle, originally developed to replace the shorter barrelled AKS-74U. The AK-105 is chambered in 5.45×39mm ammunition and is used domestically by the Russian Army in contrast to other AK-100 series rifles. The carbine is produced at Izhmash factories in Izhevsk, Russia. It is part of the AK-100 family.
== Design == Compared to the AK-74M, AK-101, and AK-103, which are full-length assault rifles of similar design, the AK-105 is a carbine rifle featuring a shorter 12.4 in (310 mm) barrel, and a solid, side-folding, polymer stock allowing convenience in transportation or paratrooper operations, while still providing a stable firing platform when extended; the AK-105 retains the ability to fire with the stock folded. The AK-105 has matching polymer furniture including pistol grip, magazines and forward handguard. It was developed to replace the even shorter compact AKS-74U, (however both rifles are in-service) that featured a shorter skeleton stock and a shorter, 8.1 in (210 mm) barrel. The AK-105 uses an adjustable, U‑notch, rear tangent sight, calibrated in 100 m (109 yd) increments out to 500 m (547 yd). The front sight is a post, adjustable for elevation in the field, while windage adjustments are done prior to issue by the armory. According to the manufacturer's web site in 2014, "Protective coatings ensure excellent corrosion resistance of metal parts. Forearm, magazine, butt stock and pistol grip are made of high strength plastic." The AK‑105 has a muzzle booster derived from the AKS‑74U that aids in reducing recoil and improving stability of automatic fire, through the use of exiting gasses.
