I bought a cheap reflex type sight from sportsman's guide. I think it is the sightmark, not that sure. I took the iron sights off of mine. There didn't seem to be an easy way to co witness the iron sights with the optic.
I can hit clay pigeons at 50 yards off hand. Not impossible shot thrown in the air, but on the ground. I got mine just for fun, works fine the way it is.
