The AK-12 assault rifle has passed military field tests and meets all of the Russian armed forces’ design and operational standards, gunmaker Kalashnikov Concern says, according to Jane’s 360.

The AK-12’s success in military trials sets it up to become the standard weapon for soldiers in Russia’s Ratnik — or Warrior — future weapon system.

Work on the AK-12 began in 2011 with the AK-200 as a base model. Kalashnikov Concern presented prototypes in early 2012, and the first generation of the weapon was also successful in military tests.

However, according to Jane’s, the Russian military requested design alterations and wanted the new weapon to be cheaper to make. The company then produced the second-generation version of the weapon, using a 5.45 mm round with the AK-400 as its base model. The second-generation model also addressed issues regarding full-automatic fire.
