Two tone
I have Mossberg 500 mariner (silver)that came with a 18 “ barrel. The new 28” is blued. Resulting in two tone gun. Cheaper than dirt wasn’t the best in price but a plus in service. Thanks.

Everything went well from ordering, shipping, and delivery. The Mossberg 12 gauge 500 barrel matched up with my Maverick 88 receiver. It was after putting the barrel that I learned there were two version of the Maverick88. Version from 1997 onward hand two arms pump action. Unfortunately, mine was a pre 1997 version with only one arm which binding of pump more likely.

Will this barrel chamber and shoot 2 3/4 shells?

Yes sir. This barrel has a 3" chamber. That means it can chamber 3" and all shorter shells.
Will this barrel fit a 590s mossberg?
Answer:
Hello Jaime! This 90123 barrel will not fit the 590S. According to Mossberg, barrels for the 590 and 590S are not available for accessory sale.
Will this fit a Westernfield 550?
Answer:
Hello again! My first impression was wrong! Fancy that. Here's what Mossberg said in response to your question: "Yes, these barrels are compatible as long as your Pump action is chambered in 12ga and has a 6-shot capacity (5 +1)."
Does it have chrome lining for steel shot?
Answer:
No sir, no chrome lining here!
