I agree that for a lot of people (me included) the Rogue Hunter is about ideal. I recommended one to somebody here just a few weeks ago.
But that Jack Carbine is marketed to a particular group who are pretty zealous about:
"Tier 1" trainers
BCM
In particular, BCM 14.5" mid-length guns
The CL barrel will be lighter, which is important because they're gonna have a lot of stuff hanging off the rail.
The CL barrel will last longer (which is somehow important even if you'll never ever ever shoot it enough to shoot out the barrel).
Anything Geissele.
The concept is viable and worthwhile with adjustments for each shooter. But that Jack carbine is carefully built for marketing.
