I'm a huge fan of the Accupoint and I use it with the LaRue mount as shown in order to get the proper eye relief. I use a 1.25-4.0 scope extensively on an AR for action shooting competition because the chevron is a good compromise between rapid up-close target acquisition and the precision needed for 300 yard engagement. I have the same scope for New England style woods hunting with a lever action rifle.
That being said, I don't use it for more focused precision shooting. I'm bringing a Leupold with a varminter reticle to find the prairie dogs. It's just easier for me to use traditional cross-hairs for that type of aiming.
Regarding the tritium, it only comes into play in extremely low light scenarios, virtually full darkness. The Accupoint has a large spiral of optical fiber on the top that illuminates the chevron and even during twilight conditions it is much brighter than the tritium illumination.
