Eye relief issue - Hawke Sport Optics Airmax 30 3-12x40mm Compact Rifle Scope 30mm Tube Second Focal Plane

So the description says eye relief is 76mm (3 inches)
In real use the eye relief is about 2.5 inches.
I had it mounted to a highly modified Crosman 1322, 14.5" barrel etc. I understand the Crosman stock for these pistols is not great for cheek weld. I put back on my Hawke Vantage 4x32mm AO. I cannot say enough good things about that scope, which has a 3.5" relief. I thought the 3" advertised relief would be enough.
I am going to give the Airmax 30 SF Compact 3-12x40 a chance on a Flashpup i just ordered. I really hope it works out with that rifle.
I have had scopes that cost 4x as much as the Hawkes and I will put their glass right up there with them. I will buy another Vantage 4x32 AO for other future projects. I kind of wish I ordered another scope in their Vantage line and not the Airmax.
Personally, I can't get a feel for a scope until it has been used on rings. So here I am. I really hope it works with the Flashpup. I will update.
