Is this a real acog it came with a manual and lense pin the glass is super clear the reticle is bright the turrets are crisp and it does work in complete darkness though it is a little dim it is supposedly a ta44-4r
Well cool. Good for you! ACOGs have superior glass in them, though that should not matter a whole lot at lower magnification like yours. It is a good scope.
I am not sure you will want to replace the tritium. You don't want it real bright in low light and in the daytime, the fiber optic should make it WAY bright. I actually put tape over mine to keep it from being too bright.
