I doubt anyone really needs this here. I thought I would post it since getting it wrong can be expensive or at the least, frustrating. The correct rings are the Talley Tactical 6 Screw Rings, part number BAT356X. Their height is 1.41" (Extra High). If you want to substitute with another brand DO NOT go by the Extra High designation, call to ensure that they are at least 1.40" high.
