I am looking for rear and front folding BUIS's
that I can utilize with an OKO W reflex sight.
I have a single rail picatinny gas blcok - not weaver, so my Armalight front mounting A2 sight won't fit well - it's rather loose.
The gas block flat (not in the grooves) is 0.602 inches above the barrel and 0.285 inches BELOW the flattop upper receiver flat.
Can anyone recommend the Bushmaster or any other front and rear folding sights that will cowitness with the OKO?
