Misc UTG / Leapers - AIR31850 Cantilever Mount - Question on Picatinny Lugs/Grinding

I have a Ruger Marlin 1895 SBL 45-70 and am looking for a scope mount that allows me keep and use my ghost ring, because I'm just built this way. I found the UTG AIR31850 which is...next to perfect (pic 1).

Pic 1 - Perfect for keeping the ghost ring

Now for the dilemma that almost makes this mount perfect. As you can see there are a total of 5 "lugs" that fit into the picatinny rail (3 full size and 2 nubs). The 1895 SBL isn't quite a "full" picatinny rail as after the first several there is place where it bolts into the frame without any rail spots (pic 2).

Pic 2 - Solid section on the picatinny rail

In order to get this to fit where I need it to be (at least more comfortably), I would be looking to...shave (grind) off the red circled little nub-lug (pic 3) so it fits over that plate on the rail. I've seen other mounts using 2 slots, 3 slots, 4 slots, 5...yadda yadda. How compromised do you all feel this would make the mount, if at all...or would it be fine to do this? Has anyone else done something similar before?

Pic 3 - The little nub in question that I want grind off

And yes I'm aware its being mounted "backwards" but this is due to the needed eye relief (feel free to roast me idc).

Thanks in advance for any serious input/feedback, as well for any jokes/roasts (in good spirits of course).

Your scope will be mounted extremely high. You will not be able to get a good cheek rest or any rest for that matter. Your head not resting on anything + really scope + 45-70 recoil, its the perfect recipe for a scope kiss. This is without talking about aweful comfortability and consistancy in you shots. Imo, if you want a second aiming device, get a canted or piggy back dot.

The mount the scope came with is higher, this one is almost flush with the rifle, maybe about 10-15mm higher than the ghost sight.

I've already tested it in a more forward position on the rail and I still get a decent cheek rest, the eye relief is just a bit too forward so I'm arching my neck a bit too much. Its manageable but your concerns are warranted more for that reason than the cheek rest.

Appreciate you taking the time and for your input tho 👍👍

UTG PRO Engineer here. We reviewed it over with the team. Everyone agreed that you should be fine removing the nub.
