i have a 39A that I've had an old Leupold 2-7 on for years. Bought the wife a BL-22 micro and moved the little scope to her rifle. I got a Nikon 3-9 for 22's with the shorter parallax and BDC. I'm not a huge fan of Nikon scopes, but it wasn't expensive, so I thought I'd give it a try. I've had it for 6 to 8 months, and it's very nice. Clear and sharp and I am definitely shooting better now that I'm seeing better with this scope. I am quite pleased.
Since I had bashed Nikon a few times in the past, I thought it was only fair that I say something favorable for a change.
