"I received mine yesterday and just tested it today in my KWA MK23. Just by the feel installing it I could tell it was harder than my stock bucking. It didn't have the 2 contact points that I expected but that's fine. When I tested it today the range and accuracy increase was insane. With my .3's I was previously struggling to push them out past 20-30 yards, my range has just about doubled. I don't know about any increase in FPS as I haven't had it chrono'd yet.

"considering the KWA products are suppose to use green gas! this is a great upgrade for anyone using propane, I have been using .25 with stock hop adjusted all the way up. after replacing with the REAPS is has more hop than I ever expected, A jump up about 25fps, so much hop I am looking into buying .30's to get the best shot possible maby even a .32? this is in a KWA KMP9...
