The Vortex Brand scope rings that I would recommend for this scope and your Mossberg MVP LC are the Vortex Precision Matched Rifle Scope Rings (34mm, 1.45"). These will provide enough clearance for your objective lens and can be found by using the link below:

If mounting atop a 1-piece picatinny rail, the Strike Eagle 5-25x56 can be mounted in 34mm low-height Precision Matched Rings, PN# PMR-34-92, as the minimum clearance option. As the X-Bolt MAX LR has an adjustable comb-height, the maximum ring-height recommendation is somewhat arbitrary, as the shooter could comfortably utilize any height, so long as it cleared the objective. A 1.0" or 1.1" height ring would also be appropriate, PN# PMR-34-100 and PMR-34-1.1.

No, you will need to purchase a mount or rings meant specifically for your firearm as not all mounts or rings will fit all firearms.
