I own a GAMO 890 and 2 CFX's,,,,, I also own 2 B-26's (one in each caliber),,,,,, that being said,,,,, go for the B-26

Thomas is correct in that the B-26 is a clone of the legendary Beeman R-9. I also own a .177 cal R-9 Goldifnger and a .22 cal R-9 Goldfinger. The only reason I mention that is because owning both the B-26 and R-9 I can tell you that the B-26 is an excellent copy of the R-9, and if you get Mike Mellick to tune it for you it just won't get any better.....
Go for the B-26, you won't be sorry..
