Where is the RRA Wilson barrel markings showing it is chrome lined and what is it marked with?  Thanks.....Trapfan

Thanks bigbore! It looks "frosted" like my Colt and Bushmaster from the chamber end and both of them are chrome bore and chamber. Just thought Wilson might put a mark on them for the chrome treatment is all.

On a RRA barrel, there is a code on the barrel at the receiver end in front of the barrel nut/ delta ring.
Go to the industry forum under RRA and you can ask Steve in a post, IM, or E-Mail what your code stands for.

I did and he confirmed I had a chrome lined mid-length by the code number.
He might be at SHOT show so it might take some time, but Steve is good about getting back to you!

Thanks GS1000SN,
 I looked mine over and it is marked 204 under the gass tube just past the delta ring with what appears to be a tiny 1 or a I out past it about a inch. I will contact Steve at RRA to confirm.
