Ring-Sight MC-10-80 Reflex Sight with Tritium for Tokyo Marui and Real Steel P90 PDWs

"Great P90 sight! Reticle is black and at least on mine, the tritium T reticle is red-orange and visible in a dark room. The intensity is perfect for NVGs, or your very own dark adapted MK1 MOD1 eyeball. It is NOT visible in ANY kind of daylight! To test it, go to a room you can make dark, look through the sight at the reticle and without moving off the sight, flick off the lights. You should be able to see the reticle after a few seconds of eye adjustment. However, again that is on the one I received.

The construction is very robust. I intend to try it on my real steel FN PS90 and see if it will hold zero. Currently, I have it on my King Arms P90, and yes, as stated by another reviewer, it will require some work to get it to mount properly. Since the metal on the gun's receiver is soft, and I do not want to modify the sight itself, I decided to use some small files and make a notch to allow the sight to sit right. It took a few minutes of tedious work, but now it's perfect and I can still use it on my real weapon.

I am impressed with this sight and do not consider the price tag to be out of line. It is very high quality. Perhaps even good enough for real steel, but that test will have to wait for another day.

Carry on, and be careful out there.

"This is close to the FN Black Ring sight but not exact, very dimmed red tritium and slight size difference. Overall nice item for airsoft.

"The sight shipped quickly, which I was very happy about after reading some other reviews about slow shipping.
The sight seems sturdy enough, but like the other review, no tritium. It does look close to the real sights used on the PS90, but probably not as solid as the real one. Also, the body had scratches on it, leading me to believe that it was used/returned from someone else. Also, it did not ship with any mounting screws.

I am going to keep it, as it is the closest thing to the real thing I have been able to find...price could have been better.
