mossberg 590a1 barrel on 590?

[normv]

Will the thicker/heavier barrel of the mossberg 590a1 work in a standard mossberg 590?

Yes, completely interchangable, it will even work on a 12GA model 500...

Why do you want the heavier barrel? Will you be shooting it so much it will make a difference? 50 rounds of buckshot through my regular 500 barrel didn't cause any problems.

yes to the 590
No to the 500.
regular old 500's have a differant means of mounting the barrel and use a screw that screws into the magazine tube where as the 590 uses a nut to hold the 590 barrel to the magazine tube. as well as 500's having 6 shot tubes and 590's having 8 shot tubes.

Partially correct. There are 18.5" AND 20" 590A1 models. There is also at least one 500 (that breacher model 54125) which also has the "clean out" mag tube. I suspect an 18.5" 590A1 barrel will fit on that 500 model, too (pictured below).

Mossberg makes it hard on the logic it uses to assign model numbers.

 

[Hoppy590]

by definition, 590's only come in 20 inch the 9 in 590 denotes 9 rounds and 9 rounds can only be achieved in the 20 inch setup

mossberg does not list any 6 shot ( 18.5 inch barreled) 590s nor do i remember them doing so. i suspect any outside source selling 18 inch "590s" is just using the name loosly.


could be wrong.

 

[Hoppy590]

oh also. a 590a1 is a 20inch shotgun i do not know of any 18 inch A1's never mind any 18 inch 590s

18.5 inch 590A1

Mossberg does make the 590A1 with an 18.5" barrel and 6 shot capacity. They just don't include them on their website. See models 51411 and 51517.

im un able to find a Mossberg referance on these model numbers. just a handful of hits on google to a few shops or listings.

regardless if im right or wrong (probibly wrong) but thats retarded model designations

Here is a link to Mossberg's Law Enforcement models I found in an old thread.

I have personally seen a shorter 590a1 (it was stamped on side of receiver) at a gun shop. 18.5" barrel and 6 shot capacity sounds right.

Going back to the original question, the thicker 590a1 barrel can be used in the standard 590 that comes with the thinner barrel, correct?
