Hello fellow enthusiasts. I just ordered a Bushnell Elite 4200 6-20x40 1/4" moa dot going on a solid egw picatinny rail on a Remington 700 sps varmint. I am wanting to get the scope as close to the barrel as possible. I am going with the burris tactical or the signatures. Can anyone tell me which height would be right? Low or Medium? Thanks guys and I look forward to hearing your responses.
