| To get the whole sight picture in the scope I need to get right up to it, like a centimeter from my eye. I had a couple other try it too, they had the problem. The guys wearing glasses didn't have this quite as much. To get it set up where it looks right to me I would have to mount it so far back on the M4 that I couldn't use the BUIS then. What am missing here? Is the eye relief adjustable other than moving the scope closer to the eye? |

Quoted:
You don't use the ACOG in conjunction with the back-up iron sight. You set the ACOG back over the top of your BUIS to gain correct eye relief. The BUIS is there only if the ACOG fails and in that case, you remove the ACOG from the weapon and deploy the BUIS. That. Like this.

| Where I put my ACOG on the rail would depend on how extended I keep my buttstock. Most of us guys who keep the stock open a bit (I open it to the first notch) have it all the way back over the BUIS, but a lot of guys who always keep their stocks closed put them far forward on the rail because the RCO ACOGs we were issued have like, 1.5" eye relief and you really got to get in there with them. |
