Bio a Question .
I used a brass tube as a shroud with a CB brake. Its been on the gun for over 8 months now. I took it apart today , doing some mods and found that the barrel was rusting, even pitted in some places. well a good scrubing down and some lube on the barrel should help, I hope.
the gun is a pump , so with the heat of the pumping condesation build up seem like a problem. with your shroud, whats to stop it from collecting moisture , and rusting the barrel like my brass shroud did. yours is c02 mine being pump, any difference.
