[1][2][3] The AGS-40 uses 40 mm CL (caseless) grenades with a range of 2,500 m (compared to the 30 mm grenades with range 1,700 for AGS-17 and 2,100 for AGS-30) and a rate of fire of 400 rounds per minute, with short burst (5 rounds), long burst (10 rounds), and continuous fire modes.

[4] A unique feature of the AGS-40 is a detachable seat that allows for more stable shooting using the weight of an operator.

[5] Development of the AGS-40 started in 1980 but stalled after the dissolution of the Soviet Union and the subsequent economic decline in Russia.

However, the project was revived in the early 1990s under the codename "Balkan", and was put into operational evaluation in 2018.

[1][7] State tests were successfully completed and the weapon was recommended for introduction into service as of March 2021.
