Ring Height question

[RollingCode3]

I have a Ruger SR22 (22lr) and I want to get a scope for it but I have no idea what is the right ring height to purchase. The scope i want to purchase is the Bushnell Trophy. http://www.midwayusa.com/viewProduct...tnumber=345044 And the ring is the Burris Ring http://www.midwayusa.com/viewProduct...tnumber=357230

What size scope ring should i get? (low, medium or high) Thanks

According to Midway's ring height chart you will need rings at least .270 inch high. The on sale rings you linked to are .450 inch so you got room to spare. The Burris 1" Zee medium are .270 exactly. I have had to return two sets of rings that fit "exactly" because they were too close for comfort and did not allow a scope cover to fit.
