The 92 Rossi is already drilled & tapped! (If we're talking new rifles, check with Rossi about what year they start D&T the 92s as I think it was within the last couple of years) The holes are under the rear sight, just tap it out & you'll see the mount holes. Rossi builds a weaver style bridge that bolts right on & obviously you'll have to use a scout style scope since its forward of the action.
