I'm setting up my Model 10 for Palma and I'm trying to figure out how to mount a Warner rear match sight. I've got this weaver rail adapter http://www.brownells.com/.aspx/sid=2.../WR_Sight_Base but due to stacking issues, it puts the rear aperture almost 2" above the barrel center line.

Does anyone know of anyone that makes a plate type adapter that bolts to the receiver?

Any assistance would be greatly appreciated.
