This is a great scope and I love everything that I know about it so far. The 34mm tube needs specific rings and the 56mm objective doesn't work with the sun shade for some reason but overall it is a great piece. I was able to track rounds on targets to 200m without using my spotting scope and I am getting the hang of the reticle. Take your time with this one. Learn to focus the objective, the reticle and the target. There is a learning curve but that is on my end. Overall I love it and will continue to buy Athlon!
