IMO it's a neat little waste of $1500. It'll just let you miss faster, and it's a .22LR anyway. The only practical purpose is to burn up a lot of ammo. I guess my perspective may be a little different than most, as I've had the opportunity to get LOTS of trigger time on a variety of fully automatic weapons while in the Marine Corps (M249 SAW, M240G, M2, Mk19, M16A2 burst), so a full auto .22LR just doesn't trip my trigger. I'd rather invest that money into a nice Bushmaster .223 Varminter or some such and have a real and practical rifle.

That's not to say that I think that anyone who wants to buy this type of upper shouldn't be able to. I fully support a lawful citizens right to own any type of firearm they choose to, even if its sole purpose is to waste a bunch of ammo for little more than novelty.
