I think you are saying that you are going to buy a set of 34-mm rings, and are wondering if you should get some angle in it to allow the crosshairs to be adjusted for the drop at longer range.
You scope will work for longer distances than your current capabilities.
If you want to add angle to the base, you need to get one which has 1/2 the total adjustment of your scope. The data on the web page should tell you how much total adjustment you have available. You need to be able to zero the rifle at 100 or 200-yds, and then adjust from that zero with the scope adjustment to adjust for bullet drop at longer ranges.
