    Hey all,

    I have a new Mossy 590a1. i put about 45 rounds through it and have had an issue since the 5th round was shot out of it.

    the magazine doesnt eject properly so the round just sits in the magazine after pumping after each shot and so it fails to load into the chamber about 75 percent of the time.

    i lubed it up but no difference.

    has anyone else had any issues like this?

    any suggestions or ideas would be much appreciated.

    thanks in advance!

    is it a brand new shotgun, straight from the dealer? have you taken it apart and cleaned it to remove all the extra oil etc? It is a used gun?

    It is new from dealer.

    I wasn't able to take it apart yet because the pistal grip is preventing the trigger from being removed. I was not able to find a utube video on how to remove the pistol grip on this model.
    Going to call mossberg today but I'm surprised bc mossbergs have a good reputation. Very disappointed.

    Do you think the oils may be causing this.?

    Any help is appreciated.

    If I remember correctly you need a long screwdriver and the screw that holds the pistol grip and stock on is in the butt. Pull off the pad and take a peak. Should be two Phillips head screws holding the pad on. Put some oil on the screwdriver so you don't tear up the pad.
    Yes the factory oils and whatever else that could be in there is a likely candidate for issues. You always want to strip and clean a new gun before use. If you don't go through it how do you know it is safe to shoot?
    The other likely issue is short cycling or babying the gun. Pumps like it rough, rack it like a man.

    I did see the screw in the back but wanted to make sure that was the way to go before I start breaking it down.

    Never new that new guns need to be cleaned before shooting. But don't I have to put oils on all the parts after cleaning it?

    Anything that contacts another surface should have a light coat Absolutely.
    There could be machining residue in there as well as bits of metal and even packing material. Always go through a new gun.

    Thanks will do. My brother In law has way more gun knowledge then eye. He took a look at it and He seems to think there maybe something malfunctioning because there is already some spots showing wear in weird place near the magazine area in the action.

    But I will break it down and clean it before sending to mossberg.

    Ty mountain man.

    Glad to help.
    You may want to post pics once you have it apart. The guys here may be able to save you the hassle of shipping out the gun.

    RG says check your spent shells for black streaks going up the side. or rough spots on the brass. Take some scotch-brite, and #9, and clean the chamber real good. Factory coatings to prevent rust while in storage will become sticky when heated up on a new gun, mixed with a little fouling will cause that.

    That's interesting. I thought they were ready to shoot brand new. Just like my pistols but shoties do get much hotter.

    Btw. The loading issue happens when the gun is cold as well. Which makes me feel like could be something else. But I will post pics of the parts when I clean it.

    Thanks everyone.

    here are some pics of my moosberg parts

    so just to review for anyone interested in trying to diagnose my issue. My Mossberg590a1 does not load when i pump the action. this happens when the gun is cold and hot while firing. Its brand new with only 45 rounds threw it. i just dissasembled it for feed back and to clean it ofcourse but if any one can help i would apprecieate it greatly as i am a novice to guns in general.

    these pics are of the parts that show wear on them. as i said the shotty is brand new so i am not sure if this wear is normal from just dry pumping it in the house and putting 45 rounds through it.

    thanks in advance.

    You definitely still have some rough spots that need to be worked in.
    It Looks like the ejector is still in the gun. If you look through the ejection port you should see it screwed in place there. Make sure the tab isn't snapped off or anything.
    Take everything out of the feed tube. Check for burrs or ruff spots. Make sure the follower is in good shape. Running a lightly oiled mop through the tube may help.
    Can you post pics of the bolt face?

    here are th pics of the bolt.
    i plan on thoroughly cleaning it tonight and the lubing it up.
    Can i use the same oil as i put on my pistols? i usually use outers nitro solvent to clean and outer oil to lube... also use balistol when i am trying to loosen up parts for break down.

    Your oil will be fine. Many use motor oil even.

    It's tough to see on the phone but it Looks like one of your extractors may be messed up. Is it bent and out of alignment on one side?

    Everything in the housing Looks good. It definitely is still in the break in period.
    Clean it up, oil it good and hit the range again. If the issues aren't gone they should work themselves out.
    Other than the extractor on the side of the bolt everything Looks fine. I could just be seeing something that isn't there due to the small pics.

    I had the same problem with my 500, it's the cartridge interceptor, the arm on the opposite side of the gun from the cartridge stop, it lifts the rounds out of the magazine so they can go into the chamber, in my case the interceptor was bent.

    did u have that problem new??

    was there an issue with factory oils or debris that caused the interceptor to bend?

    has it had that problem after replacing the interceptor?

    My gun was new, but it was a floor model, so I believe that someone pumped it wrong or something, I don't know, basically, when I first got it, I racked a shell in and the first shot went off, rack it again and nothing, third rack fire fourth nothing, it kept that up for about 10 rounds then if failed to load any shells whatsoever.I found that the interceptor looked bent and blocking the shells in the mag, so I took it out and bent it straight, put it back and it never had a problem again, to be sure I told Mossberg and they replaced the interceptor and cartridge stop for me for free, and I still have no problems with the gun.Here are a couple of pics, one with the bent interceptor where you can see it blocking the shells in the magazine, and a pic of it after being fixed to how it should be.



    It was bent sideways, not up and down.
