To answer your question, there is TWO reticule patterns currently available in the PS90 ring sight from FN.
1) Circle with dot (in either Black or White) - daylight use
2) Open T post (in Red via Tritium) - dim light use
I kind of agree with that,
1) The white one I saw (and have) is a circle with a dot in the middle for daylight use. There is a small mirror or light gathering window of some sort facing up at the rear of the sight. Even in daylight, if I shade the back of the sight with my hand the white circle and dot disappear. Even drops of water getting on the little light gathering window will make the reticule dim or go out completely. So it's not even good for a rainy day at noon. I'm betting that when I get to an outdoor range and sit down under the cover above the bench, I won't be able to see a white target at all. This sights best use is to take it off and throw it at the enemy! :lol:
A funny thing about this white sight is this... As long as there is strong ambient light, or an artificial light is shown down on the top of the sight (Like if I stand DIRECTLY under my bedroom light fixture) the white circle is clearly visible across an otherwise dark room or down the hallway. But if I take one step to the side or aim the rifle up or down or any other action that stops that light from shinning straight down into that window, the circle disappears. So I guess if you had a death wish you could shine a flash light down on top of the sight at night and get a good white circle to appear... right before someone shot you.
2) The other sight I saw had the black circle and dot. It acted just like the white one above... only that when I shaded the top of the sight with my hand to block light from the top of the sight and the black circle and dot disappeared, three red tritium bars appeared making a "T" that was easily seen. But knowing tritium fades over time and that some day the sight will act just like the white one... I decided I didn't want either on my rifle. :x
And the sights are so small in diameter, I have to move my head around behind the sight sometimes to even find the circle and get it on target. In a nervous situation the last thing I want is to have to be concentrating on getting the reticule to appear in the tiny window!
It is my opinion, that for the price of these excellent rifles FNH should have placed a much much better sight on these guns than the $9.95 K-Mart special that they come with. Oh, and the iron sights... they need some improvement bad. And while I'm at it... FNH could you please at least attempt to file down or smooth out the receiver before putting the finish on it? I know it’s a battle rifle and doesn’t need to be pretty ... but it looks like it was stamped back in the 1800's by a steam press or cast in a die set that was not lined up correctly.
Okay... I'm done now. Even with all the complaining I just did... I'd buy another one in a heartbeat. They are cool despite the flaws. And all rifles have some flaws. A little work on the sights and a piece of Velcro here and there and I'll be a happy camper. :lol:
