The AK-101 can be fired in semiautomatic and fully automatic. The disassembly procedure for the AK-101 is identical to that of the AK-74. The AK-101 has an optical plate installed on the side of the receiver for attaching scopes and other optical equipment, which will accept most types of Russian and European AK optics. The rifle accepts most synthetic and metal ammo magazines with 30 round capacity. The AK-101 has a 16 inch barrel with a AK-74 style muzzle brake attached to the barrel to control muzzle climb.
The AK-102, AK-104 and AK-105 are the designations given to the more compact carbine variants of the AK-10X rifle series, firing the 5.56 x 45 mm, 7.62 x 39 mm and 5.45 x 39 mm rifle rounds respectively. These carbines differentiate themselves from the normal rifles of the series in that they have much shorter barrels, only 314 mm in length. These AK-10X carbines, much like their rifle counterparts, were made primarily for export.
A common misconception is that the AK-101 has entered service as the main assault rifle of the Russian Federation, but this is not true; the AK-74M is still the main assault rifle, the AK-103, a variant of the AK-101 firing 7.62 mm Soviet rounds, is in limited service with selected units in the Russian army, and the AN-94 is entering limited service in the elite forces of the Russian military, some Russian police forces, and the Internal Ministry of Affairs.
