my friends sent this to a group chat we're in and i thought you might know what the one in the top left of the flag is :3
Sorry it took me a while to get around to this one!
So, this one's a little tricky and requires a few layers of explanation. This is, as far as I can tell, an AKMS assault rifle (Avtomat Kalashnikova pattern, chambered in 7.62x39mm) that has been converted to a pistol carbine using the parts kit of an AKS-74U (chambered in 5.45x39mm). This configuration is sometimes called the "AKMSU" or sometimes "Krinkov" (which is actually an AKS-74U nickname)
Notable identifiers include the stamped steel magazine inserted into the gun (which normally corresponds with the 7.62 cartridge and not 5.45), the folded swivel stock, and the stubby barrel with the muzzle booster / flash hider and compact gas block connection.
I was able to find one instance of this near-exact configuration in Payday 2, and it's listed as the "Krinkov" there. It's also classed as a submachine gun... which is wrong, of course, because 7.62x39mm is very far from being subsonic ammo, and man does that always irritate me.
By the way, in the future, you need to use the submissions tab to submit something for identification! :)
I'm just too lazy to enforce that right now =w=
