Re: Newbie-complete fail on sighting a scope
Welcome from StL. MO.
Ouch, two new components and you are maxed put on both elevation and windage?! Is that correct?
Also, no other scope or rifle to determine which is the problem?
My guess - It is either a warped rail and that should be obvious to the naked eye if it takes the scope's complete adjustment. I'd lay a straight edge on it from all angles.
If it's not the rail, it has to be the scope OR the mounting rings. Double check the install. Find a friend who has installed and zeroed optics before - also a scope that is on another gun that you can mount. Swap them. See if the problem follows the scope. NcStar is in the lower end of the market but should work fine with the 715. If it is defective, return it.
Pretty basic stuff to start. Rail, mounting, scope defect. Narrow down where the problem lies.
If you bought either at a local gun shop they should be willing to help as well.
