well what could i do there add a rubber pad or what, please expand on that thought.
there's no simple/easy solution, especially on a natural wood or laminate stock.
however, yours is painted... that changes things.
to mount a standard thin buttpad, something like you see on the factory stocks on the "Compact" and "Target" rifles with laminate stocks, or the "Deluxe" rifles with the walnut or birch stocks have (none of those have barrel bands either) and you'd have to cut the back of the stock square, make a filler to take up the part you're removing (altho a shorter LOP isn't always bad) glue it to the stock with epoxy, Gorilla Glue or whatever method you like. fill in the notch on the top of the stock... epoxy would work well for that. sand everything to shape and then mount the new buttpad.
you'd also have to find a thin pad that was close to the shape you wanted. i'm guessing that Brownell's probably has them, but i've never looked. you'd probably want one about 1/4" thick.
you don't need a thick centerfire buttpad.
on a .22 you don't even NEED a pad, you could use non skid/skateboard/stairtread tape, or find a hard plastic buttpad or make a metal one.
but it's a lot of work just to eliminate the factory plate... and there's not really anything wrong with the factory plate, it's just that the plastic one looks kinda cheezy and makes it instantly obvious that it's a modified factory stock.
don't take this as a harsh critique of your work... your work is fine, it's just the part of the stock you didn't modify yet that needs some attention!
