Hey, so I'm purchasing an SWFA SS 10x42 riflescope. I plan to get Burris XTR 30mm rings. My question is: What height rings should I get? It will be mounted on a Savage Arms Stevens 200 with an EGW one-piece base with a bull barrel. I'm thinking maybe I can get by with the extra low (.5 inch clearance) but PLEASE let me know if that is too low. I want the lowest I can get but have the scope clear the barrel WITH flip-up caps. Thank you.
