I put a Barska 6-24 mildot on the Marlin 917V that my wife bought me for Christmas. First trip to the range, I ran one box of Hornady's through the gun. It shot extremely well, but I never could focus the scope, no matter how hard that I tried. I had a splitting headache for two days because of that crappy scope. I sent it back to the knucklehead outfit who sold it to me, and I ended up eating the shipping.
Barska is, without a doubt, the worst optical device that I have ever looked through. Please save yourself the misery of a mistake that I made.
