The ARD works as designed, with no issues at all. But, the pictures need to be updated. It is no longer a bikini-style cap. Instead, it connects to the front of the optic like the caps with a T2. It gives you two flip-up caps on the forward objective—a blackout cap with the ARD behind it. You can also flip up the ARD if wanted. I removed the blackout front cap just to run the ARD. This new style is all fine and is a better option in my situation. But if someone was hoping for the older bikini-style rubber wrap around. It's not what you're going to get. So if your front objective isn't T2 style, it may not work for you where a bikini may have (Thinking Holsun users.) Four stars for the picture mix-up issue; But all in all, it connects to an Aimpoint T2 perfectly, nice and snug. It kills flash as designed.
