I had an IMI one, cost $800 before the big “Deadly Semi-Auto Assault Weapon” scare of the ‘80’s. Cool to shoot once, but not that great for any purpose. The pictured one has a fake suppressor to hide the long barrel. Reporters are liars and idiots.
It wasn't even a great pistol-type weapon even if you DID get the short barrel.
It oozed cool, though. I'd like to replace it, for the collectible angle.
