Leupold Deltapoint issue

[PrimaryBruce]

I've been having the optic for about a month now, and finally had time this morning to go zero it. Made sure the set screws on the rear were snug, and took a few shots. Windage was just about spot on, but it was shooting a little low. I decided to leave the windage alone for the time being and make an elevation adjustment. This is where everything went to hell. The arrow says "D" turn counter clockwise, so I turned it clock wise, to bring point of impact UP. I take a few more shots, and it didn't seem like it made any difference. I figured I just didn't adjust enough as having no clicks makes it tough to know how much you're turning. Well, apparently the sight came from Leupold basically maxed out on elevation as the screw would not turn in anymore to bring it up. And to make it even better, it apparently screwed down past the point of the threads in the optic itself, because it won't back out anymore either. Oh, and in the midst of all this, I managed to strip the pathetic excuse of a torx head screw. I guess my only option is to send it to Leupold for god only knows how long and hope they warrant it? Keep in mind, my first adjustment was maybe 1/4 turn in, meaning it basically came form the factory maxed out for whatever reason. Also, I did loosen the rear set screw before making the adjustment. Thoughts?

After spending $400 on this red dot, I have to say, I'm thoroughly disappointed. Especially considering all the good things I read about the Deltapoints.

Try putting a small shim under the mount as needed

Did you loosen both lock screws? Been a couple of years since I zeroed mine but I seem to remember it won't adjust with only one screw loose. Call Leupold and ask them "what next?" hopefully they'll cover it. (I suspect they will).

I loosened both upon discovering it was locked in place. Still nothing.

Got too much money and time into this gun/optic to have to do something like that to it. Edited May 23, 2015 by bruceg

This is a very common occurrence to leupold RMR owners, send it back expect 2-3 weeks turn around.

It's common? Wow, why in the world does Leupold send them from the factory maxed out in one direction like that?

The windage doesn't need adjusting, but it's flush with the optic, meaning if it needed to be backed out, it would protrude out past the optic itself and look like junk. I would expect these kinds of issues from a cheap reflex sight, but I expected much more from Leupold.

I meant stripping the tiny little screws also they are a pain to zero, once you have the windage adjusted you touch the elevation and affects the windage!!

Seriously? First I've heard of this. If so, I'm tempted to just hopefully get the thing fixed and just sell it then. I believe there's other sights that have the same bolt mounting locations as the Deltapoint. I'll opt for one of those. Can't contact Leupold until Tuesday. As someone said, I expect a minimum of 2-3 weeks... Joy.

If your elevation screw wont adjust anymore take the sight off. On the bottom side you can see where the elevation screw intefaces with the brass block. Put a little upward pressure on the block while turning the elevation screw. Should get you going again. As for the stripping out the torx heads your lock screws were still too tight. They should not strip if everything is loosened properly.

The smaller red dot sights have a lot less vertical adjustment than say a C-More scope. To ensure the most amount of vertical adjustment the mount needs to be vertically aligned with the barrel, which is about a 1 degree tilt forward ( if memory serves). I've had issues in the past with some mounts that do not have that offset built into the scope so they have to be mounted either with a shim under the scope or mount it to the frame with that downward angle.

Everything was loosened properly. It stripped because the screw went past the point that the optic was threaded. It had nothing to do with the rear set screws being tight. Their is no brass block under the elevation screw. Just a round, silver thingy, which I attempted to push on while backing the screw out, with no success as the screw is already stripped and it's not going to move, period.

Having it at a downward angle would have made it worse for me. I needed to bring it UP. Having it at a downward angle would have made it shoot even lower than it already was.

Also, it only needed to come up maybe 1.5". Leupold didn't even leave me that much adjustment on it.

The POI and POA move in opposite directions. To raise the POI, the POA must move down. Shimming the sight as Mr USA and Alecmc suggest is the correct fix. Out of curiosity, what gun do you have this on and how is it mounted?

Glock 34. Gun was milled just for a Deltapoint.

And yes, after thinking about it you're right, shimming would fix it, but it would be pretty crappy to have to shim a $400 optic because the company doesn't leave you any adjustment.

Cost me 30 shotgun slugs one day before I learned you move the dot from the aiming point to the point of impact.

So you don't adjust it like an EOTECH or any other scope where you make your adjustments in the direction you want the impact to go?

Usually if you're hitting low, you'd adjust the optic UP. Is this not the case with a Deltapoint?

Docter, Burris Fastfire, C-more and Deltapoint move dot to POI. Not familiar with Eotech. Usually do my adjustments with a muzzle/chamber laser at desired near zero range. Shotgun slug @ 50y, rifle secondary @ 25y, and pistol @ 10y.

Maybe its the milling of the slide that is off & not the Deltapoint.

I know 100% this isn't the case. I was there when it was milled and it was done by a machinist with a ton of experience doing far, far more technical things than milling a gun slide for a red dot. Edited May 23, 2015 by bruceg

But what was the mill indexed off of? Not sure on a glock but on a 1911 the barrel sure isn't perpendicular to the slide. Unless the barrel lock up angle was taken into account it would be easy to get the milled out area at the wrong angle. Just a thought.

Exactly… The base must be parallel to the barrel to maximize the vertical adjustment of the sight.

Relatedly, when the rear lock screws are tight, should the elevation and windage screws on the Deltapoint easily move? I just noticed that mine seem loose / easy to turn even when the rear set screws are tight.

[LoganbillJ]

They shouldnt move at all. I have 3 deltapoints. All of which will not move if lock screws are tight. They are set screws that tighten against the brass block that adjusts winadage and elevation.
