Hey hey,
Question, how does the tritium side of the post remain visible to the shooter during adjustments???
Is there two adjustments to be made?
First the whole post up/down and then is there a way to spin the post around w/o affecting zero?

2 pieces.

Move both at once for elevation then realign tritium top by itself.
Short answer, yes, there’s a dual pivot mechanism so that he tritium always faces you independent of revolutions to achieve sight height.
Even shorter answer: Don’t waste your time or money on tritium AR sights.
roger that.
yeah, yeah, yeah…i know.
i’ve heard all the cons on these things.
never really considered one as i buy nothing but aimpoint and have plenty of flip up BUIS; however, i bought a Larue rear and LMT front fixed sights for SHTF and if needed, they’ll be running by themselves w/o any optic.
can anybody really say that a tritium front wouldn’t come into it’s own in this instance???
Yes, I can really say that the tritium front sight on an AR is a waste of money. I used to run the exact setup you’re talking about (ok, it was a fixed FSP and A2 upper) but bottom line is, if it’s so dark that the tritium glows, you can’t see your target anyway. The only plus is that you now have a glowing green dot on your front sight. The instant you illuminate your target with a white light, you wash out the tritium anyway. Again, complete waste of money.
indeed…valid point.
thanks for saving me the coin.
I had the exact same set up in Iraq in 06-07. I thought it was cool, but I am not really sure in the end if it really did anything for me.
I may be the only one in this thread that likes the CP25F. Works great in our home. We have 3 neon night lights in the hallways etc. There is always enough light that you can easily see movement at night anywhere in our home. The CP25F shows up just fine. There is also a TLR1s on the 6920 for true target identification.
Even on that moonless night when the power is out?
The only glow sight I ever had even the remotest use for was the type you could get for the AK stuff.
Clips on the front sight block and has little spring tracks/rails that you run a piece with glow in it up on top of the front post when needed or completely out of the way when not.
Only thing that made it ‘better’ was that it was like a 1/8" blob of glow as opposed to the wee little tritium sight posts.
Ah, found a pic. The left piece will go onto an AR FSB with some help from needle nose pliers

I still wouldn’t count on it as a sole use night sight though.
Low light levels sure, but actual dark, not at all.
And note that I would never actually purchase them.
We just happened to stumble across several sets in a bunker we raided.
I concur with this assessment.
There is a very short period of time in any day that tritium sights are useful. The rest of the time it’s either too dark to see what you’re shooting at and you’re using a flashlight (hopefully) or it’s daylight and you don’t need the illumination. But if you plan to do all your shooting around dawn and dusk go for it.
