I shot a .177, rifled, Viper (not Viper Express) a few weeks ago and can't get it out of my mind how nice it was. Cocked buttery smooth, so-so trigger, super comfy stock and weight, a little twangy but not harsh at all. Accurate enough to knock the pigs over at the airgun silhouette range.
I recently bought a used R9. Better trigger, of course. Fairly comfortable, very nicely finished beech, good weight, harder to cock than the Gamo, and twice as twangy. The R9 shot like a dry-fired bow. I managed to tone it down with some tar and spring spacing, but it still seems like it's over-priced. I'm sure it would be fantastic with a pro tune, muzzle-brake, and etc, but I ain't made of money.
Dollar for dollar, comparing stock guns, the Gamo Viper, assuming the one I shot is a representative example, is a better buy. Now I see where you guys are coming from.
I thought you Gamites would appreciate that.
