Can a NV device be used with a Compact ACOG?

Yes with little to no problem. You will need to use the NV device behind the acog only. Never in front of.

Edit: Let me give you more data. Acogs work great with Gen 1 and gen 2 equipment. Both can only gather up to 20,000X light gain. Most gen 1&2 units have a manual iris which can be adjusted down to stop any bloom you may see in the NVD device coming from the reticle of the acog. Gen 3 devices gather much more light then gen 1 or 2 nomally starting at 30,000X light gain. Gen 3 will tend to bloom the reticle because of the increased light gain when using acogs. If you are running a PVS-14 you can adjust the manual gain to get rid of the bloom and see the reticle clearly. I have never used a MUM which has auto gain so I do not know how well the acogs will work with them.

I hope this helps.

Do to the design of the NVD device the image you see is not a true image but a projected image on a screen. This tends to cause the POI to change when using NVD gear in front of scopes/optics. Your looking thru the scope which is looking thru the NVD optic which is giving you a picture on a screen. Its not a real picture, its a projected image.

Now this is not always the case and some of the newer equipment has handled this problem. But I would not trust a NVD device to give me a true POA/POI until I have fully tested the unit with the scope I was using.

Thanks for the great info.  So a PVS-14 should work ok due to it's variable gain?

Thats correct you should have no problem since you can adjust the gain.

The new knight's armament pictures of the x110 SASS rifle show the pvs-14 mounted in front of the leupold day scope on the frontal rail.  they are seperated by a inch or so.  The pvs-14 seems to have a hooded device ont he front of it.  Any thought's on this? I was planning on calling them for more deatils but I figured iI would post it here to see if any people haave anyt hoguths on this.

The Marine Corps PVS-14 mounts (I believe they were KAC) all put the 14 in front of the RCO.
