I need a scope for my .223 rifle. I bought an Atec 4.4 X 14 with the side focus but it won't focus past 50 yards, so it's headed back to Bushnell, even though it's a Simmons. I would really like a Leupold VXII 4X12 AO but can't swing it right now. I found a 5X15 Bushnell 3200 with AO that looks good but am wondering about the eye relief. Does it change a lot from 5 power to 15 power. This is the best quality of a Leupold IMO, the eye relief is not critical. I have a Weaver 4X16 with AO on it right now but the eye relief is a little to critical. Thanks for any help, Don
