BUIS help needed

I am new to the ar platform, I have a flat top ar with a railed gas block. As far as I can tell the gas block rail and receiver rail appear to be on the same plane. After looking at folding sights on the Troy Ind., website, I see a folding sight specific to railed gas blocks? I really don’t want to buy something that won’t work for me, what to do? thanks

What rifle and gas block so you have…pictures would help?

Yeah I guess that would have helped! It is a windham src, ny version

Looks same plane to me. Go with the standard.

Ok cool, thanks.
