Dominion Arms 870 Barrel 12.5"

[ThreeOneBravo]

Hello,
Does this barrel require any modification to the slide or any other parts to fit my Remington 870 Express Super Magnum?

I have never tried it on a super magnum, sorry, I can't answer.

I have, just got it last week from CanAm. No 3 1/2" shells in that barrel, but fits perfect.

Yeah I know it's chambered for 3"
Just wouldn't want to do any modifications to the shotgun.
You got any pictures MrTrwitch?
