N/A Accurate CO2 Rifle

[SteveP-52]

Can't argue with the HW30/R7, I own a pair. Also can't argue with the idea of the 392/397 since I own a Sheridan Silver Streak, same rifle only in .20 caliber. Some don't like the idea of a multi stroke pumper, I'm one that doesn't mind whatsoever and for 25 yards, you'd only need 3 or 4 pumps.
But where the OP asked about CO2, still gonna stick with my original thought and the Flying Dragon XS60C set up by Mike however you want it. I'll also toss in a big plus for the QB78/79 and nicely tweaked by nervoustrigger. The gentleman is beyond very highly spoken of when it comes to them and you'd get an excellent rifle.

Have you considered a vintage Sheridan Benjamin 392/397G? Borrowed picture View attachment 440629

Those guns are very expensive these days. Based on the 3 that I have had they aren't anything special. I would rather have a QB based gun, better shot count, better accuracy and easier to maintain.
