I have one on order and am concerned it won't have enough eye relief. The specs say it has 15" of eye relief. That's sounds a little too precise to be accurate. I can't imagine a $500 pistol scope with only 15" of eye relief. This is going on a SBH Hunter so it sits pretty far forward. Plus, I have long arms. Anyone have one and if so what do you think the eye relief is on 8 power. Thanks!
