Rifle Scopes 20 MOA base for a browning BAR rifle?

[AtownBcat]

Hey guys, im trying to help a friend out with his BAR. I know it is not the best platform for long range but it is what we to work with. He has a Vortex PST but he had to use almost all
his adjustment just to get his zero(not sure he has the right bases on it). So I would like a 20 MOA base. Does anyone know who make a good one for the BAR?
