ncstar 3-9x42 ddab red dot issue

Here is what NcStar Support had to say:

Mr. DiMichele,



Hi this is Rich from the Tech Support Dept.



We can try a few things to see if we can help you and the other forum members sight in the #DDAB reflex sight from their Ultimate Sighting System combo.



· First tip is to make sure you loosen the two set screws located at the back end of the reflex sight, by the on/off switch. Make your windage and elevation adjustment as required, then you would tighten those two set screws to lock the reticle plate in place to hold zero.

· The MRD34 mount is usually mounted on the ocular lens housing, behind the power zoom ring. You can try flipping the mount 180 degrees and try mounting in front of the zoom ring, between the zoom ring and the turrets. If the mount ring will not close tightly around this section of the scope (it is slightly narrower at junction) you can apple some masking tape/duct tape to the inner surface of the ring mount to make it tighter. Then mount the #DDAB onto the MRD34 rail.



We can also dis-assemble the #DDAB over the phone to see if the reticle plate is frozen in place and the elevation screw is not engaging the slot properly on the reticle plate. This will often happen if the customer tries adjusting the reflex sight's elevation, without first loosening the two set screws. The elevation screw engagement can be pulled away from the reticle plate slot.



If this happens then often the reticle doesn't respond to elevation adjustments. It take 5-8 minutes to fix over the phone. We would need the supplied Allen wrenches and a small (micro) phillip head screw driver. My contact info is below in my signature.





Thank you, Rich.

well i must admit that this may be my issue even though it is horizontal. i failed to release the two locking screws when i first adjusted the windage. i guess i can try to just call their support line? i guess you intentionally didn't post his contact info here.

Looks like a good "Part 3" for the scope vid series.

Correct, I did not want to post his direct email as I feel any time support is involved you should "follow the process" as someone who does support, I do not like back door calls or emails. :)

I did loosen my locking screws before I ever attempted to adjust my DDAB.

yea, i emailed them the other day and i got no response. i hear ya on the support process. not in support but i came from that arena so i know as well.
 
yea i saw that after i posted. i just spoke to they guy that emailed you. he walked me through it in no time and it appears to me it is fixed. i cannot tell for sure since i didn't bring my 15-22 to work but looking at the dot with the windage adjusted out it is far right which it would never do before.

thanks!
 
as soon as i took the cover off, i really didn't need to do anything. he did say sometimes the spring opposite of the wind-age screw gets bound up. also on elevation issues failing to loosen the set screws causes the elevation barrel to come out of the groove it is supposed to sit in. after taking the cover off and adjusting my screw out it appeared to me that it was able to go far right where before it was stuck left of center. the real test will be when i remount it.

Ez,

I just wanted to make sure it was ok with Rich to post the contact info. I think Rich is okay with this and this is what Rich had to say!


I didn't want to mention the .22 LR cartridge as being a factor, without looking into it more. I just wanted to look into it further, before bring it up in my previous email.



The .22LR trajectory is going to be off compared to a Centerfire cartridge (.223/5.56) on a similarly configured AR15 style firearm. It could be a factor with you guys not having enough elevation adjustment for zeroing.



We've had similar problems when a .22LR customers ordering our higher powered full size scopes on their .22LR bolt guns. They would run out of elevation adjustments for zeroing @ 200 yards with their .22LR (match ammo) bolt guns. The scope just did not have enough elevation adjustment to compensate for the huge drop in the .22LR trajectory. When we tried the scopes on our centerfire rifles at the range, we didn't have any issues. We were able to confirm it at a range test with a bunch of new scopes on .22LR rifles. The resolution to the problem was to recommend a different smaller scope model with not as much magnification.



I don't have one of the newer .22LR AR15 clones, but I do have an older Jaeger AP-74 .22LR rifles (one of the original .22LR AR15 clones) in my collection. Unfortunately it has a carry handle on it, and isn't a flat top model… which could exaggerate the zeroing process. I'll have to check with my shooting buddies, to see if anyone has one of the Colt M4 .22LR or a S&W M&P 15-22, to do some testing on at the range.



If you know anyone in the SOCAL area especially in the Inland Empire region that would like to unofficial range test let me know. I am a member of a Private shooting club in the San Bernardino mountains and I have 24hr/7 day access to the range.



Canting the mount and optic, shouldn't be an issue at all. We've got many customer mounting these on 45̊̊ offset mounts on their AR15s all the time.



Thank you, Rich.

Honestly consider me floored by the time and knowledge and willingness to help a consumer, that I've received from NcStar. There are certain people on these forums who would just berate a company because it doesn't begin with an L... But if NcStar keeps up like this, they will someday be the giant killer.

I do tend to agree that part of the issue here is the caliber. I think on a .223 this issue wouldn't present it's self but since there are different ballistics involved, there just may not be enough adjustment to get the DDAB zero'd when it's on top of the scope, it very well may have to be canted to the side or even mounted lower than that.

Let me know how you make out with sighting it in Ez.

yea he mentioned that to me too. hopefully this won't apply to me since my issue was horizontal (my vertical alignment was fine) and i doubt i am going to venture over to the 200yd range. our 200yd range has such a tight window i may not be able to aim high enough to arch that thing at the target...:p

oh and i agree. he was very friendly and immediately dropped whatever he was doing to help me. he stuck with me until i felt i was ready to let him go. there is something to be said for customer service. it makes a minor inconvenience a non-factor on something like this when you get the help you need.

So how far away was you when you was trying to sight it in? I was trying to sight in at 16.6 yards (50') and I have a feeling at 50' the round is still too high.... Look how much the iron sights need to be adjusted to get on paper up close. I want the red dot for close up engagement and the scope for anything past 50'.
 
gotcha. i was at 25yds. if i recall i had no issues even lowering it.

prior to going to the range the second time when i discovered i had bought a crap laser bore sight i did this.

set my rifle in my bedroom and taped a target to the hall closet door at the end of the hall. i estimate this as somewhere in the range of 30' (large bedroom). i then stabilized the rifle the best i could and centered my scope on the target (already zeroed).
then i looked through the red dot to determine the location and adjust from that. once again, vertical alignment was not an issue. vertically i was able to get it in line with the reticles. at that point it was about 1ft left of center and i could only get it about 4-6" inches left of center. i know that is not very scientific or sure fire but i feel confident at that point vertical was not an issue. i will let you know how it goes on range testing
 
I'm waiting on this sight, backordered through Sportsmans. I wasn't 100% on this purchase because I didn't know Ncstar company. Glad to see a good review on the customer service validating my decision.
Thanks guys!
 
The scope I can say most definitely yes! The red dot I can't comment on yet. I'm waiting on a new elevation adjuster to arrive for my red dot and after that I need to use it at the range and then I can comment on it. As long as I can get it sighted in, I'm pretty sure I'm going to have to say yes.
 
i put a riser on my 15-22 to raise my scope up cause it was too close to the rifle. the riser is about 3/4" tall. now my scope and red dot are shooting low! what the heck. i cannot see that the scope is tilted or mounted oddly. i didn't have time to play with it. i can tell you that my red dot is most likely fixed. i was able to zero it in resting on top of the scope after i took it apart.
