Yes, it does.
The Sweet 22 is 1/4 MOA at 100 yards, so if you are at 75 yards that would be 3/16 MOA per click. I would start at 18 clicks down and 12 clicks right and see where are you and adjust from there.
The BSA Sweet 22 3-9x40 scope is second focal plane, not first.
The BSA Optics Sweet .22 3-9x40mm Rifle Scope will function as intended with a rifle chambered in .22 Magnum, however, you will need to purchase picatinny rings since the scope includes dovetail rings which would not work on a picatinny rail.
The BSA Optics Sweet .22 3-9x40mm Rifle Scope can be purchased with no additional accessories (MPN:S22-39X40SP) so that all you will need is 1" picatinny scope rings.
The eye relief is 4 inches.
Yes, this should be compatible.
Yes it does. Here is the MPN:22-39X40AOWRTB
Yes, but it will be very high and ungainly mounted in that fashion, with the scope and bore axis very far apart - it would work better on a flat-top AR.
