I used to have a flip up sight mounted on a quad rail handguard that was flush with the upper receiver rail mount.  I have changed handguards and i'm trying to use the flip up sight I have and keep from buying another one.

I'm looking for a 2 rail gas block that fits a .750 diameter barrel. I need to make sure the top rail of the gas block is flush with the rail of the upper receiver.  

Is there anyone that make one? If so where to get it?

You'll probably have to attach your other accessory to your handguard.


Edit :
With the cost of the high rise gas block, I would just get another FSB.
Cleaner, too.

Front Sight Base
It contains the gas black and the sight in one unit.
It can be USGI or aftermarket.
