Again I would have had that barrel off in no time. There’s Boeing Shield nice and thin that after it cures leaves a film you will never know is there or LPS3 a preservative; for if you want to never remove again. Both are available on Amazon. I personally was very impressed with the boeing shield after being brought up on LPS 3 which is thick . Either will leave long term protection. You don’t have to do it now maybe in the future. This is basically about whether you got a colleran or other. If you are happy with the function of the rifle then leave it be don’t torture your self. I’m assuming the barrel is pinned?My main concern about taking the barrel off isn't that I don't know how to do it, it is that I don't really have anything to put underneath the barrel to prevent rusting and the like.
Here are the direct words of the builder of my gun (Context: I was asking how to remove the barrel for cleaning/oiling the underside, since I had seen videos where that was referenced)
"Please don't ever take the barrel out of the stock. I sealed the wood and coated the barrel. You won't have an issue with it. The only thing you will ever need to remove is the lock to clean it."
I don't really have anything to re-coat the underside of the barrel with, if I were to take it off.
