it completely rocks in .177, very accurate 950 fps w/ cphp's. dropped a raven from 60 yards w/ it the other day, aiming about 1" high. that was impressive. it's an old rws 94 that i got from the umarex guys for under $100 shipped. just needed a bit of lube. this is one of the best we have now. nearly perfect design, easy to cock , accurate, and fast. trigger could be better, but it's pretty good for plastic.
