    I acquired an old scope from a friend. I mounted it on a 10-22 and tried to zero it with a laser boresighter. I have reached the limits of travel for the reticle and it is still not centered properly. Is it the mount? The scope? The rings? The rail? All of the above? What would be the best course of action going forward? Thanks for your help.

    It might be easier to assist if we had a description of the mounting, rail, and rings being used.... and maybe a picture

    ...and it could be the boresighter.

    Weaver rail and rings. I'll get a pic in the morning.

    Go shoot it. Laser bore sight tools are not very accurate. And if you still can't get zeroed it is more than likely something with the mounts. They are defective or mounted incorrectly.

    You sure it's a real leupold.

    Two things shold also be considered:

    1. The 10/22 barrel is not "screwed into" the receiver. It merely slides in and a is retained by a clamp

    There is a possibility the barrel is not square with the receiver face and/or the receiver face itself is not not actually machined square.

    2. The rail is not square w/ the receiver, and/or the rings are not fully seated in the rail slot.

    Best way to tell no matter what is simply looking at gross alignment
    - From the side: Does is the scope look like it's aligned/tilted up/down from the barrel itself?
    - From the back looking downrange/over the top of the scope: Does the scope look like it's pointed cleanly aligned with the barrel... or left/right?

    MEHavey: I shall place it in my (new) rest and check alignment. Sure wish I could visually boresight it like a bolt action.

    If you have another scope (any type/make/cheap or not) that would rule the scope in/out as the problem.

    THAT said: Worse-comes-to-Worse... You can shim the front or rear rings (depending on the whether shooting high/low) with aluminum from a soda can
    (cut with plain old scissors... about 3-thou per thickness ... may take several thicknesses)

    Works fine (the Leupold on this [email protected] yards is shimmed that way)

    Another buddy suggested the soda can trick. I've heard Burris makes rings with shims included.

    Looks like a real one, you can call leupold and double check. Make sure the rings are seated properly and the weaver rings are the same height, I've seen some that were .050" difference in height, like said above shoot the gun I don't much trust those laser bore sighters .

    As for the laser boresighters, theoretically they are centered in the barrel when inserted from the muzzle with the proper arbor. If they were off center and you were to rotate it 180 degrees the dot should scribe a circular path, right? But mine does not. That leads me to believe that it is projecting a beam that is true to the bore. Just my observation- but I am not as knowledgeable as all of y'all.

    How does Leupold verify it- by the serial number?

    How far away is the object/wall where you projecting the beam? The centerline of the scope appears to be at least 1-1/2" or more from the bore. If you are looking less than 20 feet you won't likely have enough down adjustment to meet the beam, however that does not equate with where a bullet will impact 25 or 50 yards downrange.

    Weaver makes windage adjustable rings for Weaver mounts. I’ve had to use them on a gun with an unsquare barrel.

    The vast majority of the Leupold forgeries start at VX-3 level and go up from their. So basically, their more expensive offerings.

    Doesn’t hurt to double check but virtually all Vari-X aged scopes are legit.

    If you have a good gun vise, you can always try and set it up so you can aim the irons at a reference point before setting the scope on the rail, if you can set the scope in place without disturbing the rifle too much it should allow you to get to where you would be on paper. Assuming the iron sights were reasonably well-regulated from the factory, that should be enough to get you on paper for final zero.

    If you still can't get close to the reference point, though, I would say the most likely possibilities would be a problem with the base or rings.

    Leupold will send you shims if you don’t want to cut them yourself.

    I agree that most laser boresighter’s aren’t very accurate. I have a very accurate one though but you pay for it.

    I use it specifically for AR’s and a few other specific firearms that my arbor boresighter won’t work on. I also use it on firearms that I boresight with my arbor sighter to double check.
