Help with shotgun disassembly.

[DarrenC]

Backstory -> My dad acquired this shotgun through a trade. No history on it. Only markings are Revelation Automatic Shotgun. I unwittingly volunteered to clean it up for him because it is likely the dirtiest firearm I've ever seen. I wouldn't shoot it in that condition. Probably wouldn't even cycle properly. Not sure it's been cleaned in 20y.

Google isn't a lot of help on it and it's not like anything I have. The bolt was a booger to figure out until I found a lone post that told of a pin on the bottom you drive out to break the bolt into 2 pieces to get it out.

Anyway, I'd like to get the magazine and stock tubes off the body but can't seem to get them to budge. I've tried PB-Blaster, Freeze-Off, Kroil, and heat, with no luck. I torqued on them until I was afraid of bending them.

So, I guess I'm going to clean it with them on but I really need to get the mag spring and plunger out. Seems like this end of the mag tube should unscrew too but don't want to booger it up and it doesn't 'want' to move either. Am I supposed to be able to stick a large flat blade screwdriver in there and unscrew it?

That magazine cap looks like the ones Remington used to use. Hold your hand over the cap to catch the cap and spring while using a screwdriver to pry it out. It will come out with force.

So pry and not twist?

Yes. Here is a video of removing it from a Remington. It's at about 10:30 in the video.

That does look a lot like a Remington.

If helps any Revelation was a Western Auto Branding of mossberg if i remember correctly but also common in those times fkr companies marlin stevens rem and moss to produce a variety of store label guns.

Also how much heat? My mossbergs i have taken apart some take a little some take a few mins or have done well warming in the oven for a while with some kroil on it. House wont smell good after that.
