personally i would use it on a 22 rifle and buy a much better scope for the X7. maybe a Nikon, Swift, Bushnell Elite, Leupold or something along that lines. usually the scopes in a package deal are just basic no frills to get you by type scopes, so that you can pull the gun out of the box, sight it in with a few shots and then go hunting. i have bought all my X7's without scopes. i have a 25-06 XL7 with a 4-12x40 Nikon, a 7mm-08 XS7 with a 6-24x50 Swift Premier and a 308 XS7VH with a Swift Premier 8-32x50. the Swift scopes are new to me as of las year, as i had never heard of them before, they are really good scopes, that are decently priced. check them out.
