590A1 20" Vent Rib Barrel

Insider

.410
Does Mossberg make a 20" Vent Rib Barrel for the 590A1 12 gauge?
Which 20" Mossberg VR barrels will fit?
Thank you.
 
Hi. If it’s the full length magazine, then no. If it the short magazine, then an 835 20” vent rib barrel will work.

If it’s a full length magazine tube, you can swap to the shorter one and use 835 barrels and other 590 barrels that work with the short tube.

If you use 835 barrels (other than a barrel specified for slug use) you absolutely CAN NOT use slugs. The 835 barrels for shot are over bored to larger 10 ga dimensions and using slugs will result in catastrophic failure.
