Aim off by a few feet on a new DB15

[jeffsaremi]

I have taken my new DB15 to the range 3 times so far and spent hours trying to zero the Magpul MBUS Pro sights that I bought for it.
The aim is off by a few feet in a 100 yards.
I have shows to this to rifle instructors and former marines and they have been unable themselves to figure this out.
When I adjust the rear sight all the way (as many clicks it has) the aim is still to the right by about 8-12 inches
Has anyone else had similar issues?

Sorry to hear you are having issues. Check and make sure the barrel is centered inside the handguard. If the handguard is not lined up properly, then that would most likely be your issue. Let me know if you have any issues, and we will have it brought in.

Thanks @DB
What you're saying makes a lot of sense. However I don't have the skills or tools to do so
I have contacted Diamondback and they have graciously allowed me to send my upper receiver for their examination.
Once i have it back I will keep you posted on the results.
