It's for 2 guns. I have new scopes inbound and want to buy rings before they arrive.
Surgeon / Medium Palma / Razor HD II 27x
Tenacity / Heavy Palma / Razor HD II 27x
If my calculations are right, 1.1" is probably my safest bet if I want to use the same rings on both guns. The stack height on the Surgeon is less and I don't think 1" will be enough there.
