There is nothing WRONG with that setup. If you have the $ then go for it.

Personally I dislike Eotechs on principal as all the ones I've used have died, while I've yet to kill an Aimpoint.

Personally I think Eotech and Aimpoint are both overkill for a range toy like the 15-22 and think many budget sights will do. The Primary Arms and TRS-25 are good examples of this. I am currently using an Aimpoint H-1 because I had a spare one lying around.

As a general rule the optic on your rifle should cost roughly the same as the rifle so their performance matches. In both rifles and sights you get what you pay for.

That saying is a little dated these days though.
