Both nikko sterling and Hawke are excellent scopes for airgun ranges.I personally changed to nikko because their optics suited my eyes a bit better. I have several guns fitted with the mountmaster range up to 12x50.(excellent).but for Xmas I got a x 24 gameking from jsr. I use it at x16 for most targets and x24 for 50 yrs plus. Brilliant scope for 80 pounds. It is a long one though but soon got used to it. Definitely aids long range shots.
