    New Haven Mossberg 500 Twenty Gauge

    I have owned a few shotguns. Remington/Mossberg/Wilson Combat.

    However, I have never seen an almost new looking Mossberg with a single action bar.

    I have seen pictures. However, I have never owned one-until now.


    I think I might purchase a dual action bar that I can use if "push comes to shove" for this gun. It looks as though it just came from the Mossberg factory. I do not want to be without a spare if the one action bar has a problem. According to Mossberg it was made in the fall of 1982...:)

    I just bought my first shotgun earlier this week. It's a Mossberg 500 Tactical in 12ga.

    You have no idea how much this post just saved me hours of headaches lol. I just got back from the range and was absolutely furious that I couldn't get the tube to accept more than 2 shells. I had no idea that there would be the limiter for hunting on a combat shotgun configuration. TY for clearing that up and making it super easy to remove!

    ACTUALLY, I had to refinish a Mossy 500 J.I.C. Pistol Grip shotty,
    and it was NO PROBLEM as I had seen this DIY guide already!

    Found a full stock with pistol grip in the clearance bin @ LGS #2.
    did the refinish and fitted the new stock! Now a very nice, cheap
    BLACTICAL Mossberg 500! :D

    Thanks for that great demonstration of breaking down the Mossberg shotgun to clean it. I have three Black ones.

    A friend had 500 a few years ago that wouldn't feed shells, turns out the magazine tube had so much crud and rust inside it that the spring would not push the next shell into the lifter. Total disassembly, a bit of elbow grease with a scotch-bright pad and some oil put it back into operation, should of had a new spring probably, but we got it working in about 45 minutes once we figured out the problem. Just one suggestion, hope it helps you.

    Great detailed instructions and pics. Please if anyone is substituting a full stock for a pistol grip or a Shockwave on a Mossy 500, be aware that the bolt that holds the stock on is a different length on pistol grips. If you use the bolt for the full size stock on the pistol grip, it will break the Tang that comes up out of the trigger group off, that the safety switch that sits on top of the receiver activates. The safety will be non-functional. Be sure to use the proper length Bolt when switching between a full stock and a pistol grip. This is the voice of actual experience speaking.

    Hello, can you please help me? I have a maverick 88, when I took the trigger assembly out, the bolt slide went out of place and now it is stuck as well as the action bar. What can I do to get these parts loose so I can realign them?

    This is my second post to this excellent thread... My last one was in May of 2017, where I mentioned my Mossberg 500A. Recently picked up a beautiful 500C 20 ga. that must be an early model, as it only has one action bar. I'd like to thank THR for keeping this guide up for over 10 years now. I'll be referring to it yet again now that I have two Mossberg 500's. Sometimes a picture really is worth a thousand words and this guide proves that.
