So who is a forum smarty pants then?!

Why take off the front sight? With a 4x you will not see it anyway I'd expect. (Too close to the scope to focus on) Or do you mean the rear sight?

For the removable option, you will need very good rings as you will likely be wanting the scope for long shots which will be out with even the slightest of variance in alignment. It can be done but the only ones I have seen that were accurate enough for me were on scopes upwards of $4k on rifles designed for it (over $12k).

I would actually suggest dropping back to a 1.5-6x scope and leave it on, or learn to get the most from peep sights at long range. Otherwise peep through rings would be an option, but not what I would do myself.
