Mossie M590A!

Discussion in 'Tactical Shotguns' started by Deaf Smith, Apr 28, 2010.

  1. Bumped into a Mossberg M590A1 at a pawn shop. Rather used alot (but does not seem to be shot much.) Has the bayonet lug, 20 inch barrel, a broken bead front sight. Stocks ok.

    They want $149 bucks.

    Now the question... does any company 'remanufacture' such a gun into a 14 inch barrel 'entry' gun, with the bayonet lug still intact? Yes I know it's a NFA Class II (I think) AOW. No biggie if the fee is $5 to register it.

    But if so, I would love to have a 14 incher, with bayonet lug and batam stock.

    Thanks for any suggestions!

  2. Mossberg makes a 14" 590A1 SBS and AOW but they don't have a bayonet lug. With you mentioning wanting a short stock then you want a SBS which is a $200 tax.

  3. Thanks Victor.

    I've been doing research on that.

    Was hopeing a 'manufacture' like SERBU would make one out of a 590.

    But since this gun has already been 'made', yea 200 buck fee.

    First I'd have to find out if that bayonet lug could be moved (or a lug bought from Mossburg and attached to a new gun.) Maybe a 14" 590A1 SBS would work if that lug could be bought and made to fit.

    No point in buying a cheep 590A1 and then no way to make it work as I want!

    I was assigned a 14" Rem 870 (PD owned) and gave it to a Sgt. who really wanted it. I have an 18" Mossy 590a1 mariner that I currently use (I own it). Not enough difference between a 14" and an 18" for my purpose. Close quarters I will have a Glock or MP-5 (PD owned).

    The price is right, that's for sure.

    I'm sure a good shotgun builder could do that....

    No offense, but What The Funk??? Are you a bleeperbleepin bleep? 590A1 that is "Rather used alot (but does not seem to be shot much.)" WHATever that can mean, for $150? That's a bad night at the bar!!!! How can you not buy that! and I wouldn't even get involved in that 14" game, but seriously why have you not bought that already?

    Huh? Are you retarded? $149 for a 590 is a screaming deal!!! I'd buy it just for shizzles and gigglez at that price even if I didnt need another shotgun. Beat to hell 590's still sell for $300 in my area.

    Isn't the Serbu classed as an AOW and the fee is only $5 bucks??

    $150 would be an outstanding deal for a regular 590 that's in working shape. It's even more outstanding if it really is a 590A1. Either way, buy it. You could probably easily sell it for ~$100 profit (give or take) if you end up going another route.
  11. That is true but the OP mentioned wanting a stock which would be a SBS.
  12. Well I could aways just slap a lay-away. I'll go mozzie over there tomorrow and look HARD at it again. I'm real sure its an A1 with the bayonet lug. 20 inch tube to.

    $150 for a 590A1 is a great deal. Unless it rusted out. A bead will run you under $20, unless you want one of the big dots or a tritium bead, which won't be much more.
    As for cutting it back to 14", on the 20" you're better off not cutting it back. The barrel lug is in the wrong place to do this, and there would be no way of securing the barrel to the mag tube without some serious machining.
    If you want to SBS it, get the 6 shot model. The barrel lug is already in the right place, and you won't have to replace the mag tube as well, which you would have to do with the 20" model. Even then, you may end up with a 15.X" barrel rather than a 14" because the forearm lengths are slightly different between the 500/590 models. I can't remember if the 14" action bars are the same length as the 18.5" versions.
    As for a bayonet lug on a 14" barrel, it isn't going to happen. There will not be enough room between the lug (which would be at the barrel lug, which is right at the end of the barrel) and the end of the mag tube cap, which is where the barrel loop on the bayonet itself secures.

    ETA: Just because it has the bayonet lug does not mean it is an A1. The 20" 590s (except for the Mariner) will come with a bayonet lug as well.
    The A1 will have a heavy barrel, metal safety, and metal trigger guard. If the shotgun has a heat shield it is probably NOT an A1. I don't know if the one you're looking at has one or not, but that's another way to narrow it down.

  14. m24shooter,

    If the receiver has stamped on the left side, M590A1, does that make it a true 590A1?

    That is what is on the left side of the receiver.

    Looks like this but without the sights on top.

  15. Yes, if it is stamped M590A1 on the side of the receiver than it is a true A1 model.

    Yes, that would be a true from the factory 590A1.
    I think the rollmark on the bottom of the receiver may still say 590 or 500, but if it has the "590A1" on the side it is the real deal.
    The GRS kit was sold on some A1s. Mine has it. It is a good GRS kit, and I think it runs about $70 from Mossberg if you wanted to add it. You would have to use black LocTite or have it brazed on. I have heard of some success with epoxy or JB Weld, although I would prefer the brazing.

    I bought my 590 brand new for $300, on sale at Big 5. I'd buy that thing the second I saw it.
  18. Took a look at it again. VERY thick barrel! Functions prefect. Lots of outside wear but I don't see much in the action.

    Looks like nobody wants it. Hahaha, you can guess what is gonna happen.

    I need another scattergun like a hole in the head.

    Sounds like you have a 590A1 Heavy Deaf. Can't say I've seen one without the GRS but, I suppose they exist.

    With GRS, that's a $600 SG NIB. Pick it up.
