M95 Premature firing.

“Premature firing?”…there’s a pill for that.
I’m so sorry…I believe there was a thread about this a while ago.
Yes…sorry, I couldn’t help it.
Dirt build up or something is worn. Sticking firing pin was my first thought. Take apart and clean and look for anything that is worn.
Sear my not be engaging properly and slipping. Without having a hands on it’s going to be a guess what is happening. I have three carbines and they always run well. Has the bolt been taken apart and cleaned recently?

Do you mean it fired as you pushed the bolt home?
If so - I have seen this a number of times on various milsurps over the years.
It could be a few things, weak trigger / sear spring (allowing it to drop below normal operating height), worn sear, or worn sear engagement surface on the bolt / cocking piece, etc.
Any of those would allow the bolt to close and simultaneously allow the firing pin to follow.
It would likely be enough to set off a commercial primer, especially PPU.

Ok, so it is likely one of those issues.
Before you start replacing parts, I would completely disassemble, clean, and reassemble.
Inspect all of the bearing / contact surfaces to see if anything is abnormal. If you are not comfortable doing so, I am certain a CGN member in your area would be able to assist, perhaps someone at your local range who is familiar with this stuff. If you are local GTA (Ontario), I don't mind helping.
But do the cleaning first, and see if it helps. Might just be some grease / gunk messing with parts.
i just had this happen to me on the range. i have no idea what could have happened. the only thing i can guess is the primers on the old ammo i was shooting seem like there are more pushed out or protruding so when i slammed the bolt forward, the bolt face was enough to set it off instead of the firing pin. not sure what happened.

A "straight pull" action rifle that fired before complete battery lock up wouldn't ever be my favorite rifle
Happened with my SKS. Likely firing pin is broken or corroded. Look at ghe front of the bolt. If the firing pin is sticking out and not recessed then that is the problem. You need to strip the bolt and thoroughly clean, remove corrosion and lubricate. Repalace FP if broken.

They can’t fire before complete battery lock up on a M95, firing pin cannot reach the primer if it isn’t fully in battery.
OP I would suspect gunk on the sear/trigger/springs would be the culprit. Many people when cleaning the cosmoline off from surplus state would do a poor job, or it could just be dried dirt, etc.
