Does anyone here have experience with Leupold tactical sights......either the Prismatic 1x14mm riflescope or the DeltaPoint reflex sight? If so, how do they compare to Aimpoint and EO Tech?

I'm looking for a sight for a Rock River AR-15....

I've used both. They are state of the art.

The prismatic is the only red dot 1x I know of that has a diopter adjustment. The only downside is that it has a fixed eye relief, so you can't mount it up forward.

The DeltaPoint has the advantage over similar sights with it's automatic on/off, so there are no switches to fumble with.
