I have the above mentioned rifle (.270) with a Burris Fullfield 3x9 scope that is mounted in DNZ rings. I cannot get the scope far enough back so I'm wanting to put a picatinny rail on the gun and get some new rings so I can move it far enough back to obtain the right view. I did some homework and there are lots of people who had the same problem I am having with the same type rifle and they went the route I want to take. There are numerous companies that make the rail I need, but I am perplexed on the verbiage that is associated with the picatinny rails such as a 20 MOA rail. I know this has something to do with long range shooting so you don't run out of adjustmentbut, but for me and where I hunt a 100-200 yard shot is all I will be making. In a nutshell what rail do I need?
