One of the reasons picatinny is so popular is it makes easy moving a scope from gun to gun. Accurate, durable adjustments will save you time and money at the range.Well I am buying scopes for two different guns. I am just a range junkie so I don't need all that much scope. I looked through a Swarovski the other day and it was amazingly clear. There was a mountain about a mile away and you could see the trees in definition from that far away. The Ziess scope was the same way. Outstanding clear glass but that is what you get with a 1000 dollar plus scope. These boys around here don't play when it comes to there by hunting scopes. Bolt actions and high dollar scopes is the norm for the series hunting community. However, a couple of guys switched to Arken and do not regret the change. I wish I could get my hands on one and see what it's all about.
