I traded on hear but the owner said he did not do it. Just making sure I didn’t have something special before I put it on OTD. I bought a new precision threaded barrel during black Friday. Thank you for your help.The blue color fill looks like something that someone did themselves. Did you buy this barrel new, or used?
Other than the blue, those are standard markings that I see on SIG barrels all the time.
Never seen an A22 except on goldThe ”A22” is a standard marking for SIG. Below are a couple pics from barrels on SIG’s website for example.
I believe the “22” is for the year 2022, and the “A” denotes that it was made early in that year.View attachment 6549448View attachment 6549449
