I'm getting a Nikon 6421 that I'm planning to put it in my bolt action rifle (haven't bought the BA rifle yet , I just got the scope because it was a good deal that I cannot resist, brand new for $150).
My only concern is that my AR has a fixed/non flip front sight post. Is it gonna be a problem as far as accuracy since that front sight is on the way or not a problem at all? Any other suggestions may be, like using a higher scope mount or something?
So far I have Eotech 512 mounted and for 100yards shooting bench it's kinda hard without using a magnifier.
Thanks in advance.

I don't know offhand the magnification range of the scope you are considering but the front sight post basically disappears once you get past 3x or so.
