I'm thinking about running my iron sights from my 15-22 on my M&P OR. The original plan was a PA micro dot but man I had a lot of fun shooting irons the other day.

I got the MBUS for the OR but don't want to risk melting the front sight on the block. The MBUS would also work great on the 15-22 with my red dot.

Has anyone done this and should it be pretty much on target once attached? the MBUS were about right on without any tweaks.
