Can’t find any stamp on my barrel that states twist rate, 5.56, or anything. Did the stamp get milled off when they turned it into a “light weight” barrel? Others have the same?
That run had markings under the handguards, top dead center, and they were on the smaller side.
Thanks for your purchase!
You had your answer in 12 minutes! Three cheers for BCM, a great outfit to deal with.
I was wondering this myself, as I did not see any markings on my BCM LW middy. Mine has the DD lite rail 12.0 so I never bothered to look under the handguards. Because it’s BCM, and it says so on their web site, I just took it for granted that it was HP MP 1/7 5.56
