I got my last BAM mount and it didn't have enough...

shoulder relief, so I took it to a friend of mine and he milled down the center a bit. Guess it's hit and miss. You can also file it down a tad if your scope bottoms out or shim it up higher. Yours may not need anything, you just have to wait and try it.
