i couldn't wait so i braved the 30mph winds to go out and shoot with my new scope knowing that there would be no true zeroing today. after i got the main scope relatively adjusted i started working on the ddab red dot mounted up top. after shooting about 6 rounds in the vicinity of my three closely grouped targets i had put up it was quite apparent that this thing was WAY off. i recalled someone mentioning up/down adjustment issues so i ran the gamut of vertical adjustment to no avail. i was about to give up when i remembered that my scope was semi-zeroed in so i lined the target up with the red dot, held the gun as steady as possible and looked through the scope to see where i was aiming. it was like 2ft to the right of the target but on plane. not what i was expecting. i adjusted it out to the point of the screw almost coming out and it was obvious this was not going to do the job. i looked briefly at the mount and it did not appear to be mounted oddly. in lieu of the weather i chose to end the day and regroup today since the forecast is much nicer.

anyone using this setup experience this? i guess i can shim the red dot but i am not sure what i would use. gonna look at it closer today.

i tried to find that cause i knew i had read about it somewhere. thanks. my main issue with the cant is that i am left handed..
 
Phil,

Thanks for linking EZ to my thead.

I haven't had a chance to get back to the range yet and I am waiting on my new adjuster to arrive. But I was able to mess with the stripped adjuster enough to get the dot to co witness the cross hairs. I think with it sitting so high above the bore centerline there isn't enough elevation adjustment to bring the dot down enough, I think it's just going to shoot way too high no matter what.

For me as a righty it won't be an issue for me to cant it to the left. I would assume you could do the same and cant it to the right and just use your right eye on the red dot and left eye on the scope?
 
If you mount your dot sight directly in line with the iron sights (like my pair below) the only thing you need to zero is move the dot to the tip of the front sight while sighting thru the irons. You can do this anywhere, even your bedroom. No shooting is required. All this assumes your irons are zeroed, of course. Nothing could be easier.

The mounting is commonly referred to as "co-witnessed." Same trajectory for the irons and dot. There is no reason to fold or flip the iron sights as the normal "dot firing" position is looking over the rear sight. With both eyes open all you see is the dot on the target.

thanks for the info guys.
Brett it sounds from that your issue was vertical? mine is windage. i am going to mess with it now and see what i can come up with. i guess i can try the left/right eye thing as i am a bit ambidextrous. i shoot long rifles lefty and pistols righty. my main concern was sticking my face over too far with the ejector port right there.

chuck, thanks. this scope has a red dot in top so your recommendation doesn't apply unless i am missing something.

Ez,

I "think" my problem was elevation.. Kind of hard for me to say exactly since I never did hit the paper with the DDAB! I would like to keep it on top of the scope, if it has to be canted I don't mind. Worst case scenario it could be put on an offset 45 mount like BeltFed did with his setup.

Chucks recommendation is right if you are using just a red dot with no magnification, in line with the iron sights.


Chuck,

On an unrelated note... Why do you have what looks to be a lockout for your safety selector?

You might try calling NcStar and explain the problem. Maybe you can just send back the red dot for a replacement while keeping the scope on the rifle.

Phil,

Roger that.... NcStar will allow you to do that. I asked them when I called, I explained I had the One Sighting System and only wanted to return the red dot if I could, they said not an issue.

thanks. yes this will be my next step. i have a laser bore sight i am getting ready to toy with right now and if that does not do it, the call will go out. sounds like from what i read they are reasonable in their support too.
 
well, i was able to adjust it on the frame to align it up horizontally with my scope sight somewhat. i will have to fine tune at the range because that laser bore sight was a piece of junk. i was skeptical when i saw it. it uses rubber grommets to fit the bore since it is universal. surprisingly the one for .22 did not fit. guess i have to return it to academy.
 
well, i was not able to get it adjusted in so it looks like i will be calling NCSTAR. i even decided to try pulling the scope and just mounting the red dot on the rail itself and didn't have any luck there so i just gave up. i did shoot the scope at 50yds and did OK (i'm a jittery person). i tried the quick release and attaching it back on and the zero seemed to hold well which was nice. all in all had fun and put about 500 rounds (4 different kind including Remington) and had not one single issue.

range officer came by inquiring what model it was and he said he knew a few people that are out there and have had no issues at all. he did say the club had won a Colt version and can't get it to fire more than two rounds without jamming.
 
So even directly on the rail you couldn't get the windage adjusted?

Glad to hear everything else went great and you got to put some lead down range! :)
 
Maybe someone should drop rrages a note about these scopes. As I remember, he posted here that he was selling hundreds of these MIII scopes and only had 5 returned with problems. There have been that many issues with just a few of the regular contributor's MIII scopes on this Forum. Perhaps he's unaware of problems his customers are taking directly to the Importer/Distributor.
 
Hello ever one I am new on here.And I Have the same scope on my MP 15-22.And I also got to shoot this past weekend the scope zero in just a few shots.But the red dot does not have enough ajustment to zero It was shooting real low.
 
I just sent an email to NcStar support explaining the issue that it seems we're all having with the DDAB atop the Mark III. I wanted to see what their thoughts are on this issue. I will post back what they have to say.

let me know what you hear. i was going to drop them a note as well.

yes, i pulled the scope and put it straight on the rail by itself. i couldn't locate my shot at 25yds so i just put it up and played with the scope and then the iron sights only.
 
i emailed George last night and he told me if i ship my red dot back he will send me one that he will first barrel sight so i am happy.
