Running out of adjustment sighting in.

Since reading comprehension has slipped or maybe some just don't understand here's a picture so you all can see his set up. He doesn't have separate bases nor does he have windage adjustable bases or rings.

From his original post, he stated he has a 1 piece mount like this... With rings very similar to this except they split the other way, in halves kinda like original talley rings.

I had the same problem with a model 700 VSSF 2. A real simple and cheap fix was to buy the Burris rings and use the off set inserts they have. Not only do the inserts grab and protect your optic they give you the extra adjustments.

Cheers!!

that is a option. kind of a bandaid. but he should not need to do that. it would drive me crazy not really knowing why i had the problem he is having.
 
Do you have a known good scope that you could mount on this rifle? that should prove or eliminate the mounts or scope as being the problem.
 
As I mentioned before I had a NcStar Mark III 6-24 × 50 mounted in these same rings with this same base and had no problems like this one. I went to the Vortex because the glass quality on the NC star was lacking severally as one would expect with the price range but I did not have any problems with the poi being so low like with this vortex. With the Ncstar I started out from true center and bore sighted and it was a quick and easy process. So yes I have been using this setup with other optics and had none of these issues which is what lead me to believe it is the scope in the first place.
 
since you had such good luck with the ncstar i would tell you to get another one or even a barska. but i wouldnt even suggest that to guys i dont like. it does sound like you got a lemon vortex. you buy it new or used?
 
Yeah I know right? Who needs Schmidt & Bender when you can have NcStar! The truth is I bought this rifle in January and didn't have a scope for it. My funds dried up and I couldn't afford much so I bought this NcStar to use until I could afford something a little bit nicer. For a cheap Chinese Optic it actually isn't "too" bad all though the eye box is so unforgiving you'll go cross eyed trying to look at anything to long.

I picked this Vortex up new at Cabelas last month. They had them on a pretty good sale and I have other Vortex scopes that I have had good luck with. I've went over everything the only plausible explanation is there is a problem with the scope. The base is fine and is/was mounted correctly and the rings are fine and were/are mounted correctly. Also given the fact that this same base and rings worked fine with another scope im left to a problem with the scope being the only option. It's covered under warranty so I am sure I should be able to solve this problem once I get the scope repaired or replaced. The scope behaves like it is mounted at an extreme angle which it is not.

I also couldn't agree more that Z rings are a band aid to a bigger problem. Maybe im stubborn and close minded but not a fan of Z rings. With a one piece rail and quality steel vertical split rings it really isn't rocket science to mount a scope properly. Every future optic of mine will either be a one piece rail and Warnes or Talley lightweights, at least if its on a bolt gun.
 
Maybe you got the rings halves mixed up and cause a bit of an offset there? I don't know...it's a stumper since the NC did work...I'd break it all down and start again. Make sure the recoil lug of the base is squarely placed in the receiver, etc.

You could also have the base hole opened up, this can be used to correct the off-set if there is some.

Just some ideas.
 
Grab a set of calipers or a micrometer and check the dimensions of everything. Make sure the height of the rings are the same and make sure the thickness of the base is the same on each end. Warne rings are usually good to go but anything can come out of spec. The problem you describe sounds like mis-aligned rings are "torqueing" the scope tube and binding the erector assembly inside. It doesn't take a lot and is why I always use one of these because you can destroy a scope by mounting in "bad" rings.

Ahh the old alignment points.... That align even if the rings are crooked as a dogs hind leg.
 
The rings and bases measured just fine and I really don't think the scope was being bound up at all. If the rings were binding up this scope theoretically they should have been binding the elcheapo NCSTAR. I also fail to see how a bound erector would cause the point of impact to be so low to begin with. Maybe I'm not thinking about that correctly. I've re done everything multiple times and the results are the same.
I'm going to try and have it exchanged or repaired. I am convinced it is not a problem with the mounting. There is no reason why having already had and used a scope with this setup that it would suddenly develop a problem with this new scope.

Closer tolerances could have very different effects on different scopes and the "binding" could happen on any axis depending on the direction of the mis-alignment. OR of course, its entirely possible that you got a lemon in the scope but I've had to shim my share of mounts in my life.

Not if you build your own and can assure they're true

You seem to not grasp the idea that they can be completely out of alignment and still be able to touch the points together. They aren't worth the bar stock it took to make them. Your better off with a straight lapping bar over both rings at the same time. That will tell you if the rings are aligned with each other. Points do not.
 
If it were the rings and/or base, I'd expect the same problem with a different scope. Since that's not the case, I'm pretty much left with the scope being the problem.

rear ring pointing 2 degrees right, left ring pointing 2 degrees left. ponts come together. shows straight but it lies like obama. rings way out of whack.

Yup.... You can even have one right straight and the other out 5 degrees and still make them line up.

+1

Hard to blame it on rings or mount when another scope did work.

The pointy "alignment" bars are most likely the biggest farce ever perpetrated upon the gun world.
