I have handled this weapon, but did not fire it. Knowing somewhat about you, I think it will be a good candidate for your collection. The only thing I would be thinking is extra mags...can you get them here? Also, what is the condition and color?
All I know is that the original Steyr-manufactured semiauto versions were wretched, pulsating balls of crap. Unless they used two entirely separate Quality Control departments, I can't see why the buzzguns would be built any better.
The newer B&T-built versions are at least not supposed to break when you look at them funny.
