I have a CMMG 16" Mod 4. Decent rifle but one problem: My Zero.
I followed the instructions to conduct a 25 meter zero. I was shooting from a rest the entire time. All of my shots were grouping nicely, just to the far bottom left corner of my rifle target.
I had to drop the front sight 13 clicks to raise the strike of the round to the proper elevation. What concerns me the most is the rear sight had to be moved 30+ clicks to the right from center. I might have 10 or 12 clicks of adjustment left on the right side. My rear sight appears very far the right.
It is NOT my trigger control because once I made these adjustments I was dialed in dead center on the target consistently.
My concerns. It has been nearly 20 years since my time in the Army. I don't remember making such dramatic adjustments, especially with windage. I understand that I am 42 and not 22, but still I don't think it is my sight, which is quite good.
I spoke to other people at the range who own the same model of CMMG. They are not reporting having to make such adjustments with iron sights. I plan to return to the battlesight zero and have friends shoot to see if they too are so dramatically off.
CMMG says that I can send it back and they will take a look because it is covered by warranty.
Has anyone else dealt with this type of issue? If other people's rifles of the same make are not having these issues, is it possible I a rifle that slipped through QC?
I know it is limited info, but any insights would be appreciated. Thanks,
Best,
Dave
