Does anyone have and disassembled a Mossberg 500

[KYHeadhunter02]

Long story short I gun coated an old Mossberg 500. I couldn't figure out how to remove the plug and spring. I put it in an oven and heated the gun thinking it would be ok. Now theres no resistance against the shells when I put them in. They rattle around and I have to hold the gun up to chamber a new round. Does anyone know how to get the plug out?

The plug should be a wooden dowel with an o-ring. Take the barrel off. Hold the gun upside down and the dowel should pop out the hole enough to pull it out.

The whole magazine tube threads on, you can unscrew it and the spring plug and follower will come out, plug would come out without doing this, but you may have melted the orings and the follower keeping the plug from coming out, the plug should rattle around in there when no shells are in the mag tube. Sometimes the mag tube has some type of loc tite to keep it from coming loose but you may have melted that as well, otherwise a little heat at the base of the tube may be needed to unscrew it.  I would think youtube has a video if you looked?

Short story long....tell me about gun coating. I have a project and am intrigued. Thanks

Took mine apart about a month ago. First the mag tube will be tight so don't use channel lock pliers like I did. I ended up slightly crimping the tube, the I could get the spring to work right. Use some heat on the threaded end to help loosen it up,then you can get to the plug. If all else fails there's always good old YouTube.

Before I coated it I tried shaking the dowl out. I also tried unscrewing the tube, without any luck before coating it. I was afraid of crimping it bad. I guess I should have heated it. I've researched this to death and watched a bunch of videos. Most people don't go that far in the disassembly. Thanks for the advice. I love my cheap old 500. I finally found a great choke shell combo a few years ago. Killed a bird at 55 yards one year. Not bad for a $300 gun.

Its really not difficult just time consuming. I borrowed a buddies oven that he made. It was the size of an school locker. I highly recommend not using your kitchen oven. The stuff does stink. I ended up doing my shotgun and a pistol.

Basically the needed supplies is latex, gloves, an oven of some sorts, TSP or other degreasers/cleaning agent, gun coat(I used KG gun coat) and an air brush. I purchased a double action paasche, although you could get by with a cheap HF one. You will need an air source, I used a pancake air compressor with a regulator and water seperator.

First step is to unload your weapon and recheck! Disassemble the gun as far as possible.

Then I soaked my parts in the TSP overnight. The following day I wiped everything down again wearing latex gloves. Its very important to wear gloves in the final cleaning stage to keep oil from your skin off the parts. Its also very important to get the parts as clean as possible or the coating will not adhere good. I sprayed over the factory parkerizing. You might call and speak to the manufacturer about spraying over other coatings.

Once the parts are very clean, I hung my parts up on a coat hanger while wearing gloves. I preheated the oven to 250-275 and put several parts in to prebake them. This helps to prevent runs and get a smooth cost.

After several minutes in the oven I pulled them out and sprayed them using my airbrush doing a thin coat. After painted they go in the oven set at I believe 350 for about 20 minutes.

After baked I hang them up and continue coating the rest of the parts. I started back with the original parts doing another thin second coat. I let the parts bake again and set overnight. The next day they can be reassembled.

I ended up spraying my synthetic stocks with krylon paint. So far the coating has held up really good. Ive had nicks and scratches here and there, but nothing bad.

Hope this helps.

My intent was too buy a new turkey gun and play with my 500 as a home defense gun adding parts on it. That's why the colors are what they are. The pistio was all black before.

Did you use Duracoat?

[KYHeadhunter02]

I used kg gun coat products. They make a stock coat that bonds to plastic and polymer that I sprayed the pistol frame with. My friend that I borrowed the oven from swears KG products are more durable than Duracoat. The military does use KG. I was a bit dissapointed in the how durable the stock coat was on the pistol frame. It didnt chip, but itvit will scratch and wear. Obviously you don't heat the plastic parts before or after spraying them.

Let me know if you have any other questions.
