Just cut barrel or mag tube as well?

[Willard427]

Once I get my form 1 approved, I'll be sending out my Mossberg 500 barrel out for cut & thread. It's a 18.5" barrel and would have to be 15.5" or 16" without messing with the mag tube.

Ideally, I want the barrel cut to 14", but how much will having the mag tube modified add to this project cost wise? Worth it?

It will be run suppressed full time.
