Bloop tubes have been used on rifles for many years with great success. It increases sight radius to make the front sight appear sharper and better in focus:

Anschutz made .22 rimfire match rifles with them; did very well in the Olympics. I've seen 'em on some high power match rifles 10 inches long. While one changes the resonant frequency of the barrel, it's still very repeatable from shot to shot so accuracy's not impaired.

I don't know where folks get the idea that adding anything to the muzzle will add another variable. All barrels, with or without something hanging onto their muzzles, vibrate with the same frequencies and harmonics thereof depending on their material, shape and length. It's the same for every shot fired. Adding something to the muzzle will change the frequencies it vibrates at, but they'll be at the new frequency for every shot thereafter. There are no variables in that new frequency; the physical properties of the barrel and its attachments don't change from shot to shot.

Just counterbore the barrel back as far as you want to the diameter the barrel can withstand. It'll work the same as bloop tubes and not come loose.

And you want 12 inches of rifling? Why? Starting from the breech face, chamber mouth or where to the end of it?
