I bought a bushnell trophy red dot to mount to my competition model MKII (drilled and tapped already) and i have a question about what rings to use. Its a 30mm, so the base and rings that came with the gun wont work. I already ordered the weaver base from ruger, and now i'm trying to find out what hight rings to use. I've been looking at the leupold QRW rings, any opinions? Thanks.
