Hello all. I bought a Savage Mark II B .22 LR from Gander Mountain about a year back and was lucky enough to get a Bushnell Trophy XLT 3-9x40 scope for xmas. They also came recommended with rings that are matte black Weaver quad lock 1" .22 tip off (4 aluminium straps fits upto 36mm obj lens for firearms with 3/8" grooved receivers). My rifle has holes for a mount and not a groove. I went to Gander Mountain today and asked what I should get for mounts and they told me the Weaver #16 top mount base. Which I got. BUT, the base fits on nicely, but the rings fittings aren't wide enough for this mount.Is it my rings or my mounts or both? I'm just trying to find the right combination to mount my scope and have scoured the net looking for an answer but can't find one. Hoping posting here to the experts can shed some light on what I might need? Thanks!!
