It will not focus!!! - Hi-Lux Optics Top Angle 4-16x50mm Rifle Scopes, 30mm Tube, Second Focal Plane (SFP)

I got this Scope for the fast focus know on the side.Well, it will not focus a clear picture, no matter what you adjust.I bought a scope mount, and it was said it will fit this Scope, but it didn't.So I looked and looked, and I finally bought a $70.00 plus set of rings,now I needed a raiser, and it worked! But all this turned into a Quest, and mounted the scope, and not even close a clear picture!!! So I will take my parts, and put a good Scope on my Rings and Mount. Don't BUY THIS SCOPE!!! THANK YOU!!!
