As the Soviet Union switched from the 7.62×39mm caliber AKM to the 5.45×39mm caliber AK-74, it encouraged other nations of the Warsaw Pact to follow suit. By the mid 1980s, Romania decided to switch calibers, however it was decided that the new rifle would be developed independently, and not represent a clone of the Soviet AK-74.

Arguably, the criticisms about range, accuracy, and lethality are related to the change in barrel length and twist between the M16 and M4. The earlier 5.56 rounds (the original M193) were optimized for a 20-inch (51 cm) barrel with a 1:12 twist. In 1980 STANAG 4172 defined the 5.56×45mm NATO chambering and its accompanying 1:7 twist rifling. [38]

As the design is similar to the AK-74M, the disassembly procedure for the AK-101 is identical to that of the AK-74. It is designed with modern and composite materials, including plastics that reduce weight and improve accuracy. The AK-101 has a 415 mm (16.3 in) barrel [7] with an AK-74 style muzzle brake attached to the barrel to control muzzle ...
The larger diameter, shorter 6 mm cartridge is optimized for these shorter barrel lengths, and would perform less efficiently from rifle-length barrels. The round's muzzle energy is 831 ft⋅lbf (1,127 J) versus 792 ft⋅lbf (1,074 J) for a 5.56 mm bullet, again from the same 10" standard barrel.
