Something I can help with!
I own 4 of the Credo 3-9X40 Mil Square scopes and 1 of the Accupoint 5-20X50 Mil Dot scopes.
The Accupoint scopes are made in Wixom MI out of parts that Trijicon sources from different companies. I have also read that they get glass from Meopta but I don't know that for sure. They use a wire reticle (which can break) because they have to run the fiber optic to the reticle. The fiber optic won't glow if there isn't some type of light overhead, so if you use a box blind or heavy tree cover, only the tritium will glow. The tritium is guaranteed for either 12 or 15 years and it can be replaced by sending it back to Trijicon. The Accupoint that I have no longer has the tritium and it really only glows where I can see it when I have light on it. If I am in the shade or inside, there is no glow. Doesn't really show in twilight either but the reticle is so bold, I don't need it.
The Credo scopes are heavier by around 4 oz. They are made at LOW in Japan, not by Trijicon. They have etched reticles (which can't break unless the lens does) and the illumination is battery powered. The warranty on the illumination is only 5 years.
I personally think the .05 Mil reticle on the Credo is right on the verge of being too thin. At around 5 min before the end of shooting light (30 min after sunset) to see the reticle against anything that is dark or mottled, I have to turn on the illumination.
The also, supposedly .05 Mil thick mil-dot reticle on the Accupoint is noticeably easier for me to see in all lighting but it also looks noticeably thicker to me. Which is why I said supposedly.
The Accupoint 3-9X40 duplex has .5 MOA thin crosshairs that are 8.6 MOA across.
The Credo 3-9X40 duplex has .125 MOA (.04 Mil) thin crosshairs that are 20 MOA across. So if you are wanting thinner crosshairs, definitely go for the Credo.
For reference (at max magnification):
A Leupold 2-7X33 Duplex has .3 MOA thin crosshairs and is 7.6 MOA across.
A Leupold 2-12X42 Duplex is .3 MOA thin crosshairs and 15.3 MOA across.
I have trouble with thinner crosshairs in low light, so I prefer thicker.
Also the human eye can see more shades of green than any other and it will appear brighter for longer than red. The battery life on the green Credos is significantly longer than the red.
Personally, if I were doing it over, I would get the Accupoint because of the thicker crosshairs, lower weight and better warranty but it isn't worth the cost/trouble to change from the Credos that I already own and have mounted.
Hope this helps.
