I don't have the details in front of me but a CTR is a heavier contour in all aspects. Think of the Lite like the standard 700. the D18/Roughtech at the 700 magnum and the CTR as the Sendero.
Thank you! that clears things up quite a bit!
From what I was told when I was looking at rebarreling my T3 7mag a while back, the Ctr is slightly heavier than the roughtech. The roughtech is somewhat between the Lite and CTR. By how much, not sure, but I do know that JA outdoors had some takeoff barrels, fluted, that had 5/8-24 threads. You not getting that with a Lite barrel.
Likewise, I appreciate it!
The Roughtech seems to be more what i am looking for out of the box....although overall weight and feel might not be that much different since its also two inches longer. Threading aint a big deal
