Ya I think that we are going to have to face it, those $90.00 knock off SVD scopes are complete shit!

The windage and elevation functions do not work on the damn things.
I thought that it was just the one that I bought, but now I see that they are all like this.
If you just want one for looks, I guess they would be okay,

but if you actualy want to zero the scope in to hit a target, your better off going with the iron sights on the gun.
Lets hope others read this info before they go waste their money like we all did.
