Bakalov Storm Carbine
A mix of 2 Bullpup guns - Groza 14 OTS and Bakalov Carbine. From Groza comes the grip with the rail directly on top of it, Bakalov makes up the rest, even with Grenade Launcher.
This is the weapon with most attachments - a scope, grenade launcher, bayonet, laser sight, suppressor, shoulder pad and on top of it all - an extended mag.
This weapon is the epitome of Kalashnikov based bullpup firearms.
