possibly the dumbest question I've asked...

I bought a leupold VX1 1-4x20 scope for an AR15 and have been having issues with it changing POI with zoom and range. I almost wonder if it's because of the ultra high rings I have it mounted on so question.

Nikon makes the M223 scope mount and I see it mounted on a number of fellas ARs(or similar mounts) so I assume it's pretty decent. is this mount only good with the M223 scope or can you mount other scopes with it.
 
Which way is it going?

Up and down would be normal for a high mounted scope. You will have to zero for s known distance and compensate for the rest.


Could be paralax issues also. More info please.
 
to tell the truth I have no idea. it's dead on at 50 yards on 4x but any change to zoom or range and I cant even hit paper. I used to have a red dot on it and it was dead on from 25 to 100 yards so I doubt it's the rifle.
 
Are you saying the POI changes at the same distance just by changing the magnification?
If so something is wrong with the scope.
 
another very likely theory. I've shaken it lightly and nothing rattles so I dont think anything broke loose and from the best efforts I've made to hold the gun steady while changing zoom, I believe it doesn't move horizontally. all I know is after this I'm sticking with my prostaffs.
 
If its mounted securely and level with the rifle, it certainly sounds like a bad scope.


The loose mount can rear It's ugly head somtimes and mess with your brain.

This happens on new installs, because it tightened in the wrong position and then settled in to where its supposed to go.

i say take it down and reinstall before anything else.
 
I already double checked the rings, they're solid, I bought the thing while on deployment and the warranty card says it needs to be filled out within 90 days of purchase so I dont know if leupold would even fix it if is was broken since I cant register the scope. all I know is that this is the last time I buy a scope sight unseen, based on reputation.
 
No matter the distance for which it's zeroed, changing magnification should not change the point of impact. Scope height has zilch to do with it. Going from 4X to 14X, I'd expect the center of a three-shot group to be inside of 1/2 inch from the first group. I'd figure a bit of change just from the difference in visibility or precision.

Me, I'd phone Leupold for advice/instructions.
 
A small tip is to mark all your bolts. I use a white paintmarker to mark any scope ring/scope mount bolts so its easy to see if they are turning from recoil. A drop of blue locktite doesnt hurt either.

I don't know if this matters or not, but the M223 mount is supposedly -made specifically for the 223 scope. The reason given by Nikon is that the mount holds the scope at (I believe) a 20* angle to allow for proper adjustment of the 223 scope.
 
I have a 3x10x50 Leupold vxII on mine with a Armalite high mount.
Its not lost zero in 4 years & does not change poi through the range of powers at all. Just lucky i guess.
 
Lot's of good info here, but....an AR zero'd at 25 - 100 should be on regardless of magnification change. Especially if you are saying off the paper. If the mount is good, call Leupold.

Frankly, I don't think they really care about the card or receipt, especially, if you use the word deployed in your reason why the card is not filled out.

I say call them today.
 
Sorry to hear about your scope problems. Please dont give up on Leupold they will fix it for you. Thanks for your service.

The original Nikon M223 scope mount has 20 moa built in to it. There is a newer version of the M223 mount without the 20 moa cant. The M223 mount is for a 1" tube and up to a 44mm bell.
 
Leupold WILL fix your scope regardless of the registration. They have an unlimited lifetime warranty regardless of whether you are the first owner of a brand new one or the tenth owner of a thirty year old one.
My question for you though would be whether you are seeing vertical changes in point of impact at different distances between 25 and 100 yards. Or are the changes in point of impact seen while shooting at the same distance and only varying the magnification? If you are getting a vertical shift in poi when changing distance that would be normal. If you are maintaining the same distance and only changing magnification between shots then you have a scope issue. If that is the case call leupold customer service and they will take care of you.

here's my position. shooting prone off sandbags I sighted it to abut 1.5-2 MOA on a transtar target on 4x at 50 yards(intentionally 1" high). from there I moved down to 1x and couldn't even find my holes(on a 2'x4' target that's problematic) moving back up to 4x I was hitting 1.5 MOA 1" high so I tried moving to 100 yards on 4" wide by "12" long gongs and regardless of zoom I'm not hitting but weeds are pretty thick on the hillside I'm shooting at so I cant tell where I'm hitting. I'm convinced that it's a bad scope but I guess I'm just P-I-S-S-O-F-T that I spent double on this as any of my other scopes and it's completely worthless.
 
That's pretty bad regardless of the problem.

That's outside parallax issues or any other of the common scope problems.
 
Just to make 100% sure.

You were shooting at 4X at a point on the target. You zoomed back to 1X on the same target and aiming at the same point with the same hold on the rifle and you weren't anywhere on the target at all?

If that is so, there is something definitely wrong with the optic.

Although this isn't what I think is wrong with your optic, you can check parallax by putting the crosshairs on a point on the target and move your head around while keeping the optic locked in position. If the crosshairs move in relation to the target, you have parallax at that distance. If your optic can be adjusted for parallax, adjust it so that it doesn't do that anymore. If it can't be adjusted, choose a target further out/closer and check it there. If it has parallax at all ranges, you have something wrong with the optic. All optic devices have parallax at "some range" just because they are bending light through the optic.

However, it shouldn't move 2 feet at 50 yards.
