Archived [ARCHIVED THREAD] - "FF" Barrel Marking?
Posted: 8/8/2022 10:23:51 AM EDT
Has anyone ever seen an FF followed by the twist rate as the barrel marking?  It's a new one on me.

Must be that new fast forward rifling. I hear it adds 100fps.

I don't think that's it, because it's 1x9.  I don't believe it's free float, either.

Seriously, I thought I'd seen a lot of brands of  barrels over the years, and this one has me stumped.
