If its not going to be a flattop, I would find an A1 upper and be happy.

I think whatever BUIS sights i am using, fixed or flip-up, i would prefer to have the larger ghost ring peep aperature be my default aperature for 0-200 yds.
I just bought a Troy sight. It has a slight cant to the left, is that normal?
The sight when extended does wobble left to right a little too.
The aperture design is more like the A1 sight to me.
