Default Need a flat top gas block for a traditional quad rail (not free floating)

I have been looking, but it seems like most of the replacement gas blocks are designed to go with free float hand guards. I have a traditional quad rail with an A2 style front sight. I would like to remove the A2 so it does not block my ACOG sight picture. Can anyone give me some suggestions please?imageuploadedbyfirearms-talk1393397100.419684.jpgimageuploadedbyfirearms-talk1393397122.139958.jpg

Thanks for your help!

I ended up calling a local AR builder/customizer and found out that as long as the quad rail does not extend past the original sight post, then any after market gas post will work. Even if it says "low profile." The low profile ones are just meant to be marketed to those who want a free-float hand guard.
Thanks for your help tho!
