That looks good but is the build quality as good as your favourite Hawke, and what would be the advantage of the more expensive Hawke Sidewinder I see on your rifle (Facebook) ?
At the other end of the scale, this one looked good for £75 but it only goes up to x9 magnification:-
Hawke Vantage MAX Air Rifle Scope 3-9x40 AO 1/2 MilDot Reticle Riflescope 14181
or this one at £79:-
Hawke Vantage Air Rifle Scope 4-12x40 AO MILDOT RETICLE Riflescope 14141
