Heads up, if anyone wants to buys a CAT can and is concerned about weight over ultimate durability for a particular build. Im waiting to get my noah swapped out for one within their weight specs so i havent gotten to test it out yet, mine came in 2oz heavier than expected. CAT told me that lots of the cans silencer shop is selling are mil spec overstock versions with a thicker wall for added durability.
I went back and weighed my johnny law, MOB and white bread after this and the only one not 1.5-2oz heavier than their specs is my white bread, which is actually 0.5oz lighter than it should be.
I told silencer shops dealer service dept about this, based on their response i have my doubts they will do anything about it as far as trying to sort out the mil spec ones for customers. We'll see. There is a super thin extra weld line on the back near the mount threads that CAT told me is the indicator if its a mil spec version.
All that being said, I love the CAT cans I've shot so far and their performance is extremely impressive. I have no doubt the noah would be the perfect suppressor for a 6arc gas gun or bolt gun, since they specifically designed it for that use case. I just expected mine to weigh 8.6oz without the mount and it doesn't. Their customer service is very responsive and willing to help so far, but their warranty dept has not responded yet after 4 days. We'll see
