I looked at those. They look cool, but they are twice the price of the Craddock RTR 6.5 barrels.Check out the sr25 cartel barrels. They are made for the SR25. I had d. Wilson convert one for me, turned out great. I have yet to shoot it but I have little doubt it will preform well.
If the Craddock RTR shoots like any other Craddock and is reliable unsuppressed as well as suppressed, that just seems like a solid move to me.
