Saw a deal online for a primary arms 3x magnifier thought why not. Its off as you can see... want to see if its an issue?
Do these need to be "co-witnessed"

Looks like your Aimpoint is on an absolute co witness riser but the magnifier is at a lower 1/3 height. I would want to rectify that.

Need more info. What's the sight picture look like. Definitely getting short changed in that respect, me thinks.

for whatever reason i guess i missed this : Primary Arms Flip To Side Magnifier Mount. Perfect for all medium lower 1/3 cowitness red dots. Puts center of magnifier 1.64-Inches above the top of mounting rail.
I notice it a little
So basically I need this to be compatible correct? :

Correct. Or you can get a lower 1/3 aimpoint mount from larue. I think it's cheaper than the AD magnifier mount you linked to.

Nice 
Since earlier problem has been solved, I have a question please:
I have an Aimpoint PRO and the Primary Arms 3X Long Eye Relief Red Dot Magnifier Gen III.
I believe I bought the Aim Pro without a mount and the PA Mag. as well - no mounts.
For an AR15 rail mount, what would be the best mount combination for absolute witness and/or co-witness? I see that PA is having a sale on the American Defense AD-SM-01 Swing Away mount lower 1/3 and, also, on the AD-SM-02 Swing Away mount absolute CW. As extra info., I believe I have Magpul flipup sights (Gen. II?), if I want to use them.
All help appreciated.

If you have an Aimpoint PRO, I believe it can do 1/3 or absolute co-witness with the addition or removal of an included spacer. If you are running flip-up BUIS, I think absolute co-witness tends to be better.
Thanks. I do not have the Aimpoint Pro package with me to determine if it came with a spacer or not. I did buy it from a reputable dealer.
