It looks normal to me, as far as I know 6933 has a “pencil” profile barrel that like the barrel on the 733, does not “step up” right behind the flash hider like you often see in other lengths of lightweight barrel.
Off the top of my head I want to say it’s like .600” in diameter. A longer pencil barrel would taper down to about .570” before stepping back up to form a shoulder behind the flash hider.
Colt barrel markings/barrel mfg date are pretty easy to spot though too.
Here’s mine for reference; 6933.
That’s a super cool marking.
I have two newer factory sbr colts 6933/commandos. Both just have the most recent standard M4 marking you’d see on a 6920.
Dumb question, how's it work when buying a SBR in a private sale?
Thats a badass weapon, congrats on the grab.
