Hi All,

I received my new 590A1 from an online retailer (don't think they're a sponsor) and as I was getting ready to clean it I noticed that there is an inch and a half ring of rust in the barrel, on the side that goes into the receiver. The rusted portion is very smooth and I don't think it's gone very deep. I was going to exchange it, but since I got rid of the original packaging it may be a problem. I'm still waiting to hear back from the retailer on this. I called the mossberg warranty center in Ottawa and I was told I would have to send the barrel in and they would order a new one from the states. I wasn't given an eta on how long this would take.

From what I read online this apparently a common problem with the 590A1 and a lot of people found rust on the replacement barrel as well. Should I just try and clean this myself? Does anyone have any suggestions as to how I should to it? I read that auto transmission fluid and scotch bright work well. Any advice is appreciated.



I'll try and post some pics later tonight. I'm writing this from my phone and I'm not sure how to do it now.

Thanks,


Mik
 
the issue is not enough oil when the guns a boxed, unless you see pitting is just clean it and shoot it,ones you have had a few rounds of lead and plastic down the pipe, it will no longer rust :)
 
Common issue. It's smooth to the touch, no texture to it. Mine has it too.
I scrubbed it with a brass brush and steel wool. It lessened and I shot a bunch of rounds through it as well which helped. There is just a light tinge of orange there now.
 
It's always a bit disappointing to see "this" on a BNIB firearm but in your case it doesn't seem to be serious.
As others have mentioned….just clean her up, shoot it and enjoy safely. 590A1's are a beast of a shotgun.
 
Never saw a Mossberg barrel that didn't have rust in it from the factory.Just chuck up a drill with a shotgun cleaning rod and wrap 0000 steel wool around the bore brush.Some guys like to use oil, I like Mothers mag & aluminium polish to give the bore a nice shine.YMMV.

By "liberal oil" do you mean oil that doesn't work? Oil contaminated with pig feces? Oil that corrodes or otherwise ruins what it touches?
Please don't reveal where to buy it, I don't want any...

Liberal oil is the best oil there is! I recomend everyone buy as much as possible!
It is obtained in a similar way as olive or peanut oil but has steps used in oil and gas production. The liberals are first washed then boiled to soffen their crusty exteriors and remove grime and feces, then they are put into a large hydraulic press and squeezed until their greasy oily innerds are expelled through their pores into a reciptical leading to a heated atomaspheric fractional distiller.this step seporates the useable oils from the greasy sludge. The next step is to run the oil intoa catalytic reformer used to convert the oil-boiling range molecules into higher octane reformate (reformer product). The reformate has higher content of aromatic oils and cyclic hydrocarbons). An important byproduct of a reformer is hydrogen released during the catalyst reaction. The hydrogen is used either in the hydrotreaters or the hydrocracker.
There are also deslters and desulpherizers and a host of other processes.
The long and short of it is that liberal oil is made from liberals and should be used at all costs on/ in everything. Hell use old liberal oil to fertilize your lawn.
Liberal oil is a non renewable resource but there are alternatives when we run out so use as much as you can as fast as you can. ;)
