Basically the crappy trigger of a bullpup, the looks and ergonomics of a VHS tape, you have to muzzle F yourself to charge it, crappy fixed molded sights, reliability of a Yugo and it's "greatest" feature, that it can provide a worthless less powerful rail attatched backup gun to a rifle requires NFA paperwork. I'm fairly open minded and love to see innovative firearms, even if they aren't all that practical , but this looks like a dozen stupid ideas all molded together.
