If you mount the scope on the Mini-14 using rings, you should be able to remove the hand guard, the slide, and everything else for a typical field strip, except for the bolt. The bolt removes from the top of the receiver and the scope mounted with rings will prevent it from being removed. You can still access the bolt for cleaning from the bottom side, though, with the trigger assembly removed, so that's not a big deal.
Here's another option...Mount your scope on a B-Square rail instead (not an aftermarket brand, a real B-Square). Using this see-under rail mount, you will be able to retain the use of your iron sights also, a nice option. When you go to field strip the rifle, the scope & mount will remove as a single unit, thus preserving your scope settings. With this unit removed, you can then perform a complete field strip, including removal of the bolt if you wish.
My only gripe with B-Square is their wave-type lock washer used for this mount is too flimsy (may loosen mount during firing). You can replace it with a better wave lock washer from any hardware store for just a few cents. When you do that, ditch the snap ring and spacer from the mounting knob and you'll get a much better bite on the threads located on the rifle's cover plate (a replacement plate comes with the mount).
If you don't want to go this route, at least go with the see-through type scope rings. As far as I know, the see-through rings made by Weaver work only on the Mini-14 Ranch model. If yours is a Ranch, these see-through rings will let you use your iron sights, and also lift your scope enough to perform a good field strip.
