I bought a Vortex Viper PST 6-24x50 that will be here in the middle of the week. I have a hunt this coming weekend and would like to have it mounted and sighted in before this weekend. For this to happen I need to order rings before the scope get here so they will be here in time. I planned on ordering some from the vortex website but can not decide what height to order. My scope base is about 5/8 of an inch above the barrel and it is a picatinny base. Can anyone help me with what height I would need. Sorry this is my first time buying scope rings and without the scope in hand it's hard for me to decide what to buy.
