looks unwieldy

That is one tricked-out Kalashnikov.

I've seen Grozas with power scopes, Vals with ridiculous rails that make it look like a tricked out Vikhr and an AK-74M look like an AK-12 (isn't the AK-12 technically an AK-74M on steroids?) due to the massive kitting but putting that huge Russian NV/IR scope on a small rifle such as an AKSU-74 is just funny.

...Which makes it hilarious in hindsight, after some research which somehow indicates that night scope is one of the few legit scopes for an AKS-74u.
