Thanks. I'm hoping so. I found the measuring for ring size thread on here but the rings and base will be here soon enough so I guess we shall see. I know its an annoying noob question but just figured id fire it off anyhow just in case some one had a definitive answer.I have vortex low on a 20moa base with a dmr. The dmr is a 50mm and are obviously stuby and short. I'm gonna say you will be more than fine with a pst to be honest but I'm sure someone else will have a concrete answer for ya
