>>27702280I owned one. They're nifty.
It fits into a laptop case, it fits a 33rd glock mag. Mine was in 9mm. It's reasonably accurate, 4-5moa at 100 yards with the iron sights. It's way reliable, never a misfeed or jam, I only got stovepipes on the last round of a 33rd mag. The charging bolt recoils with the buffer, so don't put you're hand there if you're a deer-hunter stance kinda guy.
Problems with it, the plastic it's made out of absolute shit. You can scratch your initials in it with a rusty nail. Said stovepipes eventually melted a cool semi-circle against the ejection port. The grip split into two like a cheap plastic water-gun. The front sight post is shitty, but I had the fugly plastic kinds with the neon-transparent sight leaf.
That said, the gun is my ideal home-defense weapon for non-gun people. With a single-point loop sling and a 33rd mag a little kid or disabled person could hold back basically any threat. That said, it's probably total crap for a professional unless you absolutely need a carbine that folds into a laptop or one of those satchels mailmen carry around.
