"I sent one back years ago for the power ring. Wasn't much better when it came back."
I've had the same experience with a VXI 2x7. I think it's just the nature of the beast. The only time I've been disappointed with Leupold factory service.
The 2-7's have always had a stiff magnification ring. I've had every generation of the 33mm 2-7's and the late production VX-2's were a bit better than previous 2-7's.
