Size in mm for the ARD Threaded part only for Aimpoint P.R.O.
I would like to purchase one. However, $62.00 for the entire flip up cover and ard is crazy, $34-40 dollars for OEM one is also crazy. Anyone know the size or where to get an after market ARD? Ebay has some but I have to know the size. The one from the comp M4 just falls into the PRO flip up cover. I think it is a 30mm and the PRO maybe the 33.6mm?
Well since no one seems to know, I have located a ruler in mm. I will measure it and try to post it here for others trying to find a less expensive option.
Well, without removing the flip up cover it appears to be approximately 34mm. I am assuming a 33.6mm is the size but not 100% certain.
I also see a 34.6mm on the site which they say is for the comp m2 series. Wouldn't this be the same as the PRO housing?
PM me.

Opps. Dupe
Done!

I will measure and post size when I recv this one so folks buying the PRO will know what to look for. I couldn't find anything stating its size on google etc... But for oem 20 bucks shipped seemed like a good deal.
I have a Brand New Aimpoint PRO factory mount.....I bought a extra mount just to have if I ever needed it and I doubt I ever will, Ill sell it cheap if anyone's interested ?? Just shoot me a "I.M." if thats what you need.....
Okay got it today! Excellent member to deal with is Airborne_Infantryman! ARD Model for the PRO is M68-ARD. Best I can measure on a mm ruler is 34-35mm. The ones I saw for aftermaket was 33.6-34.6 in size. The 34.6 I believe is the one for the pro and signicantly cheaper than the OEM. Bout don't waste money ask before if it is the same as the part #M68-ARD. Sorry I can't be more specific on the measurement I don't have a mic/calipers.

Where are you finding them for $20 shipped? I Googled for a while but keep coming up with the ones for $39 + shipping and higher prices too.
They do have several Aimpoint ARD's on that huge online auction site I will not name, for sale tonight.
