Just got an Aimpoint Pro for my Spikes AR.
My irons are pretty spot on at 25 with a center hold.
I can't seem to get the optics on though. I'm low at 25 & 50 yards with the elevation adjustment maxed out.
If I understand terminology correctly it seems to be a 1/3 co-witness. But I can't get the dot lined with the irons sight picture.
Is it as simple as removing the spacer in the mount which they say is to be removed for shotguns & sub-guns?
Any suggestions on what I need to do?
Just realized I had the Aimpoint mounted at the rear of the rail. Too far back to allow use of the irons. Would mounting it at the front of the rail make a diff?
