20 moa rings

[MATSUBOB]

Anyone know if any company makes 20moa ring set that will work on a picatinny rail? Can't use a tapered base as the rail is machined into the receiver and don't want to use ZEE rings as I need a quick removal option.

Barrett--as in m82-a1 .50 BMG, makes the Ex-rings. they are a nice setup and by changing the position of a single pin, you can change from 15 moa to 40 moa.
