Great sight. I've had mine since last September. The CJ is a great sight, but the Axcel is WAY faster and easier to setup. THe 2nd and 3rd axis adjustment is much easier to set than the barrel assembly on the CJ. Only drawback is that you needa specific allen wrench that is included for adjustment of the 2nd and 3rd axis, and if you don't have it.......your SOL. I lost mine. [&:][8D] I've gotta make another tomorrow on a grinder so it will fit and I can get things tuned up and adjusted.
