"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.

"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.

"This will NOT fit on a King Arms P90 without modification! If you look at the bottom picture and towards the right end, you'll see a small tab that juts out slightly; the KA P90's upper receiver DOES NOT accommodate for this tab. You'll have to either dremel out the tab off the optic or create a small notch on the upper receiver for the optic to fit into (I plan on doing the latter). It's not terribly difficult to do, with the proper tools, but it's still quite inconvenient to deal with. It'll mount solidly, but will be noticeably canted

Also this sight is NOT illuminated! I believe there is no tritium to power this sight (Tritium takes YEARS to decay beyond functionality). I had anticipated this since identical products elsewhere did not advertise any illumination features. The reticle is black and the T-shape type which you can see on the P90's wiki page, they're the exact same besides this model not having any glow. The sight picture is crisp and clear, though FOV is somewhat limited due to being such a small sight. This is also a NON-MAGNIFIED sight so technically there's no eye-relief distance or parallax effect, but you may need to get close to get a clear picture.

Construction seems pretty good. The exterior is metal and feels robust enough for any airsoft application. However the rear lens seems somewhat shoddy and appears slightly offcenter.

Overall this is a decent sight but rather overpriced in my opinion (even with coupon codes), especially because there's no tritium as advertised here. I couldn't justify this being past $70, but for the benefit of all evike customers I bit the bullet on this one. If you're after the classic P90 look, this is perhaps your only best other than scavenging across the web for a used CA or TM red dot module.

Hopefully this helped, feel free to ask me questions regarding this sight on the facebook comment section below.
