I finally got my CAT VB6 Ti and tossed it on my 14.5" Proof, using a long AI Nano mount to clear the gas block. I couldn't resist adding the matching ODG M9 to the pic.
The sound and gas reduction are both excellent! I would not consider it hearing safe at this barrel length, but I could see it being that on a longer barrel, which is its intended use case. I only have 40 rounds through it so far, so we will see if there is any change in sound over time. I didn't get any noticeable gas blown back in my face and had no signs of any additional carbon anywhere inside or on the magazine. At 100 yards I found no measurable shift in poi. It seems like a solid choice for a longer barrel/ DMR/ precision setup.
I was planning to start a longer build today, to use this can in more of its sweet spot, but then I saw that Craddock Precision has some 11.5" RTR barrels in stock and I love a shorty 6 Arc, lol! Now I guess I need to find another can to go with that one, thinking maybe DA CT5P...
For anyone wondering about the gap between the handguard and the suppressor, I got you. I measured it, it is exactly the thickness of 4 post it notes.
