Handguard length for future 12 GB

[Bigs28]

I use a 12" and a 9". My 12" is a midwest industries suppressor compatible which is actually 12.625" so my suppressor sits inside the handguard over an inch. I would not shoot it with a break on and not the suppressor because it would blow the handguard apart. My 9" handguard leaves a couple inches between the end of handguard and beginning of suppressor.
