We do a lifetime rebarrel program on our rifles. We just charge the cost of the barrel blank. Full re-chamber, paint, etc. if you shoot it out.
The nice thing about these Skunkwerks projects is that we use a lot of the R&D that goes into these systems to pump new tech into current and future models. I'm almost certain the ClymR will get this new barrel profile as a permanent addition to the line-up.
Who makes your barrels? The Lite Saber barrel is awesome.
