The Russian Mosin Nagant Forum

If posted to the wrong forum, please move and notify.
New to this forum. Bought Mosin Nagant from crate, cosmoline galore. Some existing small repairs to the stock. Serial numbers match. Have never fired one. Cleaned it and (unintentionally) probably reassembled it with the trigger pin missing. The bolt was not disassembled for cleaning. The trigger is floppy and the bolt will now not remove from the receiver. I have sufficiently chastised myself and need help, not kicks.
Grasping the trigger with pliers and pulling down does not release the bolt from the receiver nor relieve the cocked firing pin. The rear tang screw is covered by the cocked bolt and the rifle cannot be disassembled. Need to remove the bolt.
Probably somewhere, sometime, the same has happened to someone else. Hoping that there is a simple non-destructive solution to this problem. I have envisioned several ways to disassemble the rifle, but all involve damaging or destroying some component or another-- which violates the intent of this forum and my own desires.
Solutions and suggestions appreciated.

Re-read the section on re-assembly of bolt.

Excellent tutorial.
It is my assumption that the bolt for my rifle was last disassembled/assembled by a Russian armorer prior to the rifle being packed in cosmoline and into the crate. I did not/have not disassembled the bolt nor adjusted it in any way. And cannot find any instructions for disassembling the bolt while it is in the receiver.

Because it has to be taken out of the rifle to disassemble.

The original problem is that the bolt will not remove from the rifle. My original post with details of the problem has disappeared. Without those details, the succeeding posts make no sense. Was seeking help, no offense intended

I recently had the same issue where the trigger pin was not installed with a rifle still packed in cosmoline. Open the bolt and while pulling the trigger with about 20 lbs of force or more see if you can sharply pull the bolt out.

If you have a long small tip screwdriver, you might be able to trip the bolt stop reaching under the bolt with the tip.

If the trigger pin is broken or missing, pulling down on the trigger would depress the sear spring/bolt stop enough to remove the bolt. My bet is that the screw for the sear spring/bolt stop is loose. Pull the bolt to the rear and look down inside, you should see the top of the screw, the top of it should be flush with the bottom of the bolt channel.

Here's a trick. remove the handguard. Pull the bolt back as far as you can. Unscrew the rear cocking piece and remove it. move the rest of the bolt forward. You can now get to the rear action screw, remove it and front action screw and the magazine, pull the action up and out of the stock. Now you have access to the trigger mechanism and sear spring to troubleshoot.

Not sure what is the handguard.
"Pull the bolt back as far as you can. Unscrew the rear cocking piece and remove it. move the rest of the bolt forward."
This was one of the things considered. I suspect that the firing pin will just rotate and will not unscrew from the cocking piece. And will the cocking piece rotate 360 degrees continuously while the bolt is in the receiver at all? My rifle is at my workshop remote from the house and computer.

This works; I've done it in the past, and posted it to the old forum; I don't have the pic anymore, unfortunately.

The screwdriver-- like a jewelers screwdriver or larger? Inserted under the firing face of the bolt or where? With bolt open or closed?

Something with a 6-8" long shaft, bolt open, from the bottom rear under the cocking knob. You might need 3 hands. Last time I tried what I just described I had to get down on my hands and knees.

Thanks to all of you for taking the time to read and respond. I think the 3 hands part is a given. Not available to me. Among things I tried was the stainless steel piece found on the side of the "rubber" on some automobile wiper blades- long and slender.
Since my initial post, I bought another "piece" of a Mosin and placed the barrel next to my stock in the best alignment possible. Marked the trigger pin hole on my stock on the bolt handle side and drilled a 9/64 hole until it hit metal. The 9/64 is slightly smaller than the trigger pin. Alignment not satisfactory. Enlarged to 1/4 and probed with scribe, alignment not quite suitable. Drilled 5/16 and used a 12d common nail in the pin hole.
Success! Bolt is out, rifle is disassembled. The stock already has 2 other round plugs on the bolt side into blind holes as there is no plug on the other side. I wonder why, but that is the way it is. The hole will be plugged.
The pin was absent, as I suspected from the start.
This was one of the ideas I envisioned before I posted
My rifle is Russian, 1943, CAI Georgia Vt for the importer.
Would a new thread be better about the "piece" of Mosin I acquired this week? Sad case!
Thanks again.

You drilled holes in your weapon? You gotta be fuckin kidding me.

He had to Oh shit

1 hole.
Now the other Mosin acquired this week- only parts of it are there and with some modifications by others-- no-nos on this forum. But what if I work to bring it back as near original as is practical-- is that Kosher?

Actually he didn't have to, you can tear one down with the bolt intact once you get the cocking piece off.

Old but true, you can't make a silk purse from a sows ear. We on this forum deal with history. You can't put several parts of different rifles and have factual examples of true history.

Success! Bolt is out, rifle is disassembled.

A Pyrrhic victory. A rifle ruined. Why would you come on here, ask our learned advice, then not only ignore it, but do precisely what we say NOT to do. You are either an idiot, a troll, or both. You have a bright future ahead of you as "Gunsmith to the ignorant", Bubba G. Smith.

That's not how that works unless you happen to be some time traveling Soviet Armorer from the past. As it is the first rifle is now ruined and you can try to bring the second back to original but by no means should you try to present it as original then.
