Built this one today for my friend to give to his dad, who is a retired cop.

A buddy of mine has a Mossberg 500A 12ga pump that had been sitting in the back of a closet for a long time and collected a lot of dust plus some surface rust. We decided to break it down and give it a good cleaning. The barrel wouldn't come out of the receiver.

Looked at a few videos on Youtube and they all show the barrel almost falling out once the magazine bolt is unscrewed. Sprayed the barrel/receiver joint with WD-40 and let it sit overnight but it's still stuck. Any suggestions? Is the chamber steel hard enough that I can use a brass rod to knock it out from inside the receiver?

That poor shotgun. It might be hard enough to do that, I'll ask my gunsmith. Hopefully he gets me an answer in less than 2 weeks... He's always busy.

This might be a stupid question but what position is the action in while you try to remove the barrel? IIRC you have to hold the action about 1/3-1/2 open for the barrel to unlock. I don't own a 500 (Rem 870 guy) but I have taken the barrel off of a 500 and I remember it was a PITA finding the sweet spot for the barrel to unlock.

Update... I can't get him on the phone. Seems his phone is out of order again. :/

Thanks for trying.

Tried again, paying close attention to position of bolt and running the slide through its range whilst pulling/pushing/twisting, and still no go - the barrel is in there TIGHT and never budged.

As far as I can tell, there is nothing inside the receiver holding the barrel (but not 100% sure). I don't see anything that would retain the barrel in this exploded diagram (other than the magazine screw).

Side note: You can't always depend on exploded diagrams. Was working on a different shotgun that someone had torn down and couldn't get back together. Downloaded an exploded diagram but couldn't get the hammer to go back in right. Found out that the spring that propels the hammer was shown backwards in the diagram.

This might sound silly but I would make sure the barrel can come off. If Mossberg has a serial number search, I would check the model and variant just to be sure. If it can come off I would soak it in WD-40 or similar oil for a few days. If it won’t come off then I would secure the action in a vise and tap on the barrel/tube support (see attached pic) with a wooden dowel and rubber mallet. If it won’t come off after that then you’re in gunsmith territory.

Good idea. I'll check it out.

For the last two days, I've been giving everything a shot of WD 3-4 times a day and then tapping on the barrel and receiver with a deadblow hammer. I also unscrewed the magazine bolt and rapped the bolt with the deadblow, trying to drive the receiver off the barrel. Tried hitting the barrel on the sides to maybe loosen things up - no luck. I'll wait a few more days before getting very rough with it.
I don't have a vise that I would want to clamp a gun into. Guess I need to invest in one.
I hadn't thought about using a wood dowel. Looked around the garage - no wood dowels and all my scraps are soft wood. I think the Atwood's down the road has some hard wood dowels.

Thanks for the input.

I have an old AT500. I'll take a look at it tonight, and post up.

SouthArk370Z · 09-13-2019, 02:24 PM

Went ahead and took everything out of the receiver except the ejector. It's held in by a screw and I don't want to mess with it if I don't have to. Gave it a shot of WD-40 in case we want to remove it later.

The bolt has some rust on it (not terribly bad but it made me cringe a little when I saw it). I'm guessing that the gun got wet at some time and there is some rust where the barrel and receiver mate. The guy that owns the gun is out of town for the weekend and I'd prefer if he did any enthusiastic hammering on it. I'll keep soaking it down with WD-40 until he comes back.

Maybe you can wiggle, rotate slightly, the barrel in the receiver using a strap wrench and vise to break it loose.

Tried it but it wouldn't break loose. But I was afraid to put too much torque on it. I'm going to wait until my buddy gets back and let him decide how much force to use. Until then, I'll squirt it with WD and bump it with the deadblow every few hours.

Everything else seems to be in good shape. A few quick strokes with a small brass brush gets most of the rust off of the bolt and pitting is minimal. All other parts just need a good cleaning. The bluing has seen better days but I haven't found any big pits in the steel.
