Mossberg 500 12 Gauge Shotgun Disassembly

Mossberg 500 12 Gauge Shotgun


The nice folks over at lifelibertyetc.com have just posted a video on how to disassemble and reassemble the Mossberg 500 shotgun.

here's their description of the video:

Next to the Remington 870, the Mossberg 500 is one of the most common shotguns available today. In our latest issue of The Range Bag, we'll show you how to disassemble and reassemble this handy 12ga shotgun.

They even posted it in two sizes, depending on how slow your internet connection might be.

Here's the small version, and here's the large version.

It' not a bad idea to give their bandwidth a break and right click on the link, them download it to your hard drive, rather than viewing it live. You will probably want to watch it more than once, anyway.

While you are over there, have a look at their other products, including stickers, coffee cups, pins, shirts, and lots more, all guaranteed to tick off the gun banners on sight!

Yes, but can they completely disassemble that 500 using common garden tools? I think I'm still the only person to ever have done that little gunsmithing trick.

With what garden tools are you refering to, All you need is a punch to remove the trigger assembly pin. The rest you can remove by hand.

This video was a big help after not breaking the gun down for a long time. Much better than the factory instruction manual.

Sure beats the manual. I am giving my wife a 12 ga. Mossberg 500A with a Knoxx SpecOps stock for Christmas Monday. Wrapped with the shotgun is a CD with your video on it. Thanks for the great video.

Thanks for the video. I have a High Standard Model K-120 and there are many similarities to the Mossberg 500.

Thanks. Great video.
Now. How do I clean it. Can you add a video for that.

Why couldn't they just write that in the manual?!

It should be assembled and ready to go. You might ask the guy in the shop to show you how to field strip it for cleaning, and maybe pick up a cleaning kit while you're at it, though.

Thank you so much for this video. I was so stumped on putting this gun back together, the slide wouldn't function, I laid out the peices next to the computer, watched the vid, and it slid right back together perfectly.

THANKS MAN! I'm stoked. I am buying a 500 today...and I have a lot more confidence about buying it now. You rock!...so, nudge nudge, a video in the works for cleaning?

I have just recently purchased this 500A and the magazine only holds 2 shells....How do I remove the plug to fit more shells?

To remove the plug, unscrew the cap at the end of the magazine tube. Then, you can try to shake it out, literally. Mine wouldn't eject, kept catching on the little rubber gasket around the plug. To coax it out, I applied pressure on the magazine tube with a cleaning rod. That sent the plug out with no problems. For me, at least!

Hey the gun show is in West Palm Beach Florida Nov8th & 9th and I intend to buy either the Remington or the Mossberg 12 gauge 18.5" for home defense. It is a better weapon for my wife than my Springfield
.40 caliber sub compact. I had a remington 20" combat ut sold it, was a great gun.

I just purchased a model 500 and it contains the plug. The manual does not address removal and it looks like you must remove the magazine tube to do it. Trying to pull it through the hole that the cap screws into, if that's even possible, would seen to leave the o-rings in the tube

Hello,

When I purchased my Mossberg 500, it came with a pistol grip (not attached). I was hoping someone could tell me how to attach the pistol grip to the shotgun itself? Thank you.

gun wont pump after 1st shot any ideas?

 
At Monday, December 15, 2008 6:52:00 PM, Anonymous Anonymous said...

if you fire it, it will pump, if you do not, you need to pres the small button next to the trigger guard. Also, i need to find out how to disassemble the magazine tube, i think the follower is crimped into it, and wont come out when i remove the tube from the gun. any advice?

Best site I have seen yet! Here is my delema: I have no probs changing out my mag plug, untill today... I reinserted it after changing slug to game barrel. Headed out to hunt. Loaded the gun, and something was not right. Came home and found the spring tangled in the tube. How do I remove the spring??

I stripped my Moss 500 down to replace the trigger group. When I finally got around to putting it back together, it wouldn't work. I downloaded the video, and followed the instructions and wow, it works fine. Thanks for the help.

My slide does not "just slide out the front of the receiver." Everything else is fine, but it's retained by something and I can't see what. Rifles I know, Remingtons I know, Mossbergs I don't.

 
At Thursday, April 16, 2009 7:22:00 PM, Blogger Mike said...

I have a Mossberg 600AT and my slide doesn't just slide out either. I've got the rest of it apart and soaking in some gun scrubber.

 
At Thursday, April 16, 2009 7:29:00 PM, Blogger Mike said...

Some of them have a soldered ring around the tube. You have to unscrew the tube from the receiver and take it down that way.

I have an Ithaca 12 ga. automatic Model 51 Featherweight magnum with 30 inch barrel, 3 in. magnum shells and full choke. Works great. Mostly use it for nuisance beavers. How can I remove the plug to increase my shell capacity from 3 to 5?
Thanks!

You can't, really, as the barrel mount makes extending the tube impossible. I refitted mine with the barrel and tube from an 835.

I have a 500A 7 shot with wood forearm and stock. I'd like to swap out the wood for a synthetic tactical style stock and forearm. Does anyone have a suggestion of which make to use that will install easily and fit/perform properly?

I like the Mesa Tactical and Cavalry Arms adapters that take AR stocks and grips. Great ergonomics.

Thank you, thank you. Was trying to clean a Western Field M550ABD when the bold fell out. Come to find out it's the exact same as Mossberg 500. Great vid- keep up the good work.

How do you take the bolt apart? My wife can field strip this thing. The video is missing the biggest mystery of my last week.

the video is great, but i have to take the pistol grip off to get to all the goodies. its a pain in the butt. is there any tricks to getting the trigger housing out without removing the pistol grip from the reciever?

On the older model 500's where the slide doesn't "just slide off the mag tube" use an adjustable wrench, put some cloth on the mag tube to protect it, and give it a twist. Unscrew it, and then pull it free.

For those with a Mossberg 500 who would like to increase the tube capacity from two shells to five, it is easier than you think. As has been said, you just unscrew the cap on the end of the tube and take the barrel off. Then, look down into the tube, you should see the end of a small diameter wood dowel down in there inside the spring. Point the open end towards the ground and give it a couple shakes. The end of the dowel should come out, but it won't fall out because of a couple of o-rings on the dowel. Go ahead and grab the dowel and pull on it. It should slide right out with a little help from you. Now, put the barrel back on and screw the cap back into place. You may now load 5 shells into the tube instead of 2. Enjoy!

Apparently the video to reassemble a Mossberg 500 doesn't work. Just my luck. Now I have a table full of parts and can't get it back together. The instruction manual sucks. Any hints??

Just purchased a Mossberg 500 Persuader and knew there was a mag limiter. I'm sure someone has already covered but here goes anyway... To remove the limited simply unscrew the end cap from the mag and remove the barrel for safety reasons. Feed rounds into the mag until the wooden dowel pokes out. Grab the dowel and pull it out gently as there is a couple of rubber o-rings around it. Replace barrel and mag cap and your 500 now has a 5 round capacity. Simple! You're welcome!
