Like 300Spartans said, it won't fit. I have a 10/22 and I just bought a 715t flat top last night. When I tore it down for cleaning, I was surprised at how tight the shell fits over the 702 that it covers.
Even if you did manage to make the 10/22 fit, you wouldn't be able to actually secure it in the shell because the takedown screws will have nothing to hold.
