Hello,
I recently got a boneyard Red Fire Mosin Nagant and it has a nasty slamfire issue.
It may not a true "slamfire" issue as with VSR's and such, where the bolt flies forward and maybe shooting a round, but its equally nasty.
This is what happens:
-Rotate the bolt handle up
-Rack the bolt back
-Rack the bolt forward
-Gas and a round leaves the barrel. Amount of gas and rounds varies each "shot."
-Rotate the bolt handle down
Oh, and another weird thing. I don't know if this how its supposed to be, but racking the bolt doesn't seem to engage the trigger at all. Rather, the pulling the trigger doesn't seem to engage anything else.
Any help with this would be greatly appreciated. Its a really nice rifle that I would love to get it running again. Especially since its the version with rubber bayonet and scope.

Have you tried opening the bolt? May want to look up a manual first

Outside of maybe damaged O-rings, I wouldn't even know what to look for... This might be more mechanical...

This might change things. After digging around for disassembly guides, I found this on reddit:
https://www.reddit.com/r/airsoft/comments/2sjhtd/just_bought_a_boneyard_mosin_nagant_gas_rifle_off/
Luckily I know a guy with a lathe, but probably have to join reddit to see if the guy can send me the files for it.
Now that I'm home, I'm going to open this rifle up and check anyway.

Sorry for multiple posting like this... So, I opened up the Mosin, and I found something that completely broken. Not really sure if this constitutes as a "firing pin," however it is the piece that connects to the trigger and it looks like brittle pot metal on the inside. I found this piece lodged in:  When I removed that piece, it matched up perfectly with the piece I pulled out before hand:  In reality, its snapped precisely at the corner:  Any suggestions? I thought about JB welding it, but with the FPS this supposedly gets, it will probably snap again real fast. |

JB weld will probably fail but I have been pleasantly surprised with it in the past the pourose nature of the zinc oxide might contribute to a stronger bond. There also appears to be multiple surfaces to coat. If it fails you're back to where you are so an inexpensive gamble with nothing but upsides.

I think the problem will be, despite what adhesive I use, is the lack of surface area I'll have to play with. See that gap in the in the middle of the snapped off area (in the last pic)? Thats a screw hole for the top screw on the part with the circle shape at bottom. I really don't have a lot of area to play with.
I decided to go ahead and make a Reddit account and message that poster (maybe I made these posts too soon or without thinking them through all the way). Hopefully I'll get some good news.
Worse comes to worst and it can't be fixed, this could always be fodder for a springer mod.
UPDATE: I heard back from the guy on Reddit, and it seems like my problem was much bigger and worse than his, and his part that broke is completely separate from my part. I'm beginning to side with the idea of commissioning someone to make a spring mod of it. SECOND UPDATE: Found this here, hopefully solving all problems. www.evike.com/products/54569/
