The AKMSU (Attributed name: Russian: Автомат Калашникова Mодернизированный Складной Укороченный ) is a compact carbine version of the Soviet AKM assault rifle in 7.62 caliber of disputed origin.

Design and Origins

It is a matter of contention whether the AKMSU was actually manufactured by the Soviet Union or was simply a one-off production, a "Khyber Pass Copy" from Pakistan's Khyber Pass region, an area known for diverse and unique weapon production in small shops.[1]

One alleged genuine AKMSU model is in the possession of Royal Armouries in Leeds, United Kingdom. It is the most well-known model attributed with the AKMSU name. However, it is actually a custom model, composed of a Chinese manufactured Type 56-1 receiver combined with a 1977 dated AKM trunion. Its other custom parts include a muzzle brake, which is required for the correct functioning of the rifle and contains an expansion chamber to correctly cycle the rifle. The muzzle brake has many grooves machined into it for increased heat dispersion. It also has a custom hand guard.[1]

Although no authentic pictures of the AKMSU are known to exist, a number of Russian and Western sources attest to its existence.[2][3]

AKMSU-like firearms can be produced by combining an AKMS receiver with an AKS-74U gas system, front trunnion, and receiver cover.
