folks I have a very accurate 223 cal youth axis. stock model. still has the cheap bushnell 3-9x40 scope. as we all know the bolt handle can interfere with a larger dia scope over 40mm. Question....what is the largest model of Nikon scope I can put on this gun with some good rings ? I don't want to raise it to high because of cheek weld issues. I order all my scope through mail order and don't want to return it if bolt hits back end of scope when I lift up the bolt to load more shells. would a Nikon 5-20x42mm Monarch Nikon work and what kind of rings ? wonder what all scopes u guys use on the stock 223 axis. thanks. Marty
