(Many companies do use A3 for a removable carry handle but really should use the A4 terminology.) So the A4 removable carry handle does have A2 style sights built in! Clear as mud, huh!
Yep, clear as mud on a foggy day. I think I understand though.

For what you want to do it doesnt matter, get it sighted and leave it. After that whether it tracks true or not doesnt matter.

Honestly both bcm and spikes likely source the internal sight parts from dpms. What matters more is the actual handle itself. It doesnt take much varience in height to be too far out of kilter to not be on paper with max adjustment on the front sight post
The DPMS is worth the try, so I'll try it. Thanks.
