Trijicon has come out with a new version of their 1-4X24 scope that doesn't have the bell on the front end so it should be usable on more (longer) actions BUT the eye relief is listed at only 3.2" which is pretty darn short for heavy calibers. Why they chose to fix the mounting problem on this new model but then only have 3.2" eye relief is just disappointing.

The problem I see with the illuminated Leupold is that the electronics or battery can fail just when you need it whereas the Trijicon illumination is pretty fail proof.
