RE: BSA PANTHER SCOPE??
BSA and Barska are GARBAGE, JUNK. You can alsoput Simmons and Tasco in that same catagory.
Go to ebay and buy a used Nikon Buckmaster, Burris Fullfield II, Sightron SI or SII, or Bushnell Elite 3200 and don't look back. Any of these scopes can be had for less than $200 and are light-years better in terms of optics, tracking, and reliability holding zero.
