The Nikon monarch 3 2.5-10x42 has the longest combination of tube body length, eyepiece length, and eye relief of any scope I've been able to find. Even better than the Monarch 5, which has a shorter body *and* less eye relief.
I'm hoping to Pete that it turns out to be a good scope. That combination of lengths opens up a number of loooooong action rifles like the Vanguard and Kimber 8400 to me.... Barely.
The next "best" for length is the VX-2 3-9x40, but I've had one, and for good reasons, I didn't like it and won't buy another.
