I just picked up a Tasco Bucksight 3-9x40 from Walmart for my little 17 mach2. Is this the same as a Pronghorn? I looked on Tasco's website and didn't find it anywhere on it. I have one on my 10/22 with no problems so I figured it would be ok on the .17hm2. I was wondering if it is the same as a pronghorn, just packaged for walmart. Seems to be an ok scope for what I do with the guns that it is on....mostly just shooting paper at the range.
