What size scope rings do I need for a 4.5-14x 40mm Nikon buckmaster?

It has a 1 inch tube, so it needs one inch rings. I'd personally pay 5 dollars more and get a one piece mount. They are more secure and leave one less part to move or fail. Great scope that will work for years and years.

1 inch rings, medium height

Good choice i got one yesterday.did you know that they are discontinuing them? Anyway thats besides the point. You want to get rings closest to the base and an old guy who seemed to know his shi* had told me get mediums. He knew exactly what to do and right after gave me good info.
