I finally got a carry handle and noted that the elevation knob's markings are unlike what I am used to on an fixed A2 upper. Instead of a 8/3 setting, this one has a 0 marking that then goes up to 20.
The guy I got it from said it came on his Stag Arms rifle but I don't believe Stag Arms made it, especially with Eagle Arms on the windage knob. I don't doubt it was on his rifle but I suspect someone else put it on the rifle between him and Stag Arms.
Can anyone tell me what the forge marking means? Is this a quality carry handle?
How do I go about zeroing this? Got a link for instructions?
Here are some photos of what I am talking about:
An AR without a fixed carry handle is new territory for me so any help would be appreciated. I guess I am just slow to change from what I was trained on.
