Hey, everyone. Thought I'd share the knowledge I've picked up working on my (new to me) shotgun! It's an old 190 in 16 gauge. First time tear down was a bear, especially for a deep clean and polish. If this is the wrong sub-forum, please let me know or maybe a moderator could move it. Thanks!
Just a quick detailed breakdown of the Mossberg 190 bolt action shotgun. There's three models; 185, 190 & 195, chambered in 20, 16 & 12 gauge respectively. Breakdown should be the same for all three, maybe with minor variations. I can only speak of behalf of the model 190. When I bought mine, it was definitely neglected and covered in old cosmoline and surface rust. Cleaned and polished with 0000 steel wool to get it where it is now. Without further ado, let's get into it!
NOTE: I'm not a certified gunsmith, nor do I take responsibility should something happen on your own gun. I'm only doing this to share knowledge.
Another note: A good supply for replacement parts is Havlin Gun Parts or Numrich Gun Parts. I've bought from both and they seem to be pretty good as far as quick shipping and parts supply.
These are the tools and supplies I'll be using to clean my gun. Only thing pictured is gun cleaning solvent, but I'm using the Remington brand in the spray can. Phillips screwdriver is #1, unknown what size flatblade. Just find one that fits snugly in screw groove without slipping. Tweezers pictured were not used. Red bottle is Outer's Choke Tube Grease.
First off, obviously make sure your gun is empty and the magazine clear. This gun only holds three shots total, two in the magazine & one in the chamber.
Next, remove the bolt by opening it, holding the trigger down and sliding it out the back of the receiver.
Flip shotgun over and remove the flat and Phillips head screws on either end of the mag well. Flathead won't come out of the plate, don't worry. Just loosen it so it's free of the receiver and the plate will come off after removing the Phillips head. Take care not to lose the Phillips head, it's rather small.
Now, gently separate the stock and the barreled action by pulling them apart. I found the best places to grip are the forend and barrel just in front of there. A careful tug should be all you need to separate them. Trigger and magazine release come out with the action. Set the stock off to the side for later if you plan to do any cleaning work to it.
Flip the action over and you'll see four flat head screws. I've labeled the screws for their respective parts. The two for the magazine catch are the same and the other two are their own sizes. Hard to mix these ones up. When reinstalling, I'd suggest a dab of Loctite to keep them from working loose like mine did. Also remember, the flat "L" shape piece goes UNDER the mag release. I tried putting mine back together the opposite way, didn't work well
