I want to scope a 10/22. I'm looking at the Nikon P-22 2.5-7x32 BDC 150. I've been comparing it to the same Pro Staff model. Which is better and what is the difference? Is the P-22 a good choice and is it a quality scope? I was also wondering about the rings, are the Nikon rings the best to use? Any better options for a new scope $200 or less? This is my first 10/22, an Altamont Classic V, and I want to do it right. Thanks!
