FT scope for a break barrel springer

[mrgeoff]

I can only get to 24x zoom under 400mm in the airmax.
The 32x is too long.

Got a front AO bushnell which is lovely glass, but way too long.
Most specs for the SF bushnell only close focus down to 20 yards or so, and I need 10yds for FT?

Got my eye on the Athlon Helios 8-34 which will just fit at 15.5inches, 2 issues though, it seems quite heavy, and still only focus down to 15 yards.
