I shoot lefty because of being blind in the right eye and I'm starting .22 PRS type shooting. I purchased a March 5-42 HM while waiting 16 weeks for my lefty Vudoo V22. While waiting, I mounted it on my air gun and I couldn't be more pleased. The wide angle image and superior optics put this scope in the highest class in my opinion. I did notice that both the parallax and magnification knobs were on the stiff side. The scope comes with a plastic magnification throw lever that worked great on my air gun. Not so much when my lefty V22 arrived. Because of the need for the throw lever and the large magnification range, the scope design puts the throw lever way over on the left side of the scope. That's fine for right-handers, but left-handed bolt actions interfere with the throw lever. Below 15x it just gets in the way of the bolt handle. I've sold the scope and replaced it with a ZCO 5-27. I loved it except for that one issue and left-handers maybe should look elsewhere.
