I was shooting my ’92 carbine chambered in 25-20 the other day, and the action locked open. I was able to unload the magazine tube from the front end so the gun is safe and clear, but something is obviously broken internally and has locked the action up. The cartridge lifter can be moved up and down, and I cannot see anything broken when looking in from the butt stock side. The pin on the right side ( hammer retaining screw, red arrow in pic) seems to be sticking out a lot farther than on my other carbines, and I suspect it to be related somehow to the issue. Since the action is open, the hammer is under spring tension from the hammer spring and I’m worried that if I try to remove the hammer spring screw with the spring under tension I’ll really bugger things up.
I know how to disassemble a working carbine, but in this case the action is locked open and I cannot drift out the finger lever link pin and am reluctant to try and remove the hammer spring screw with the action open. I’m hoping one of you here can suggest a way to get this gun apart in order to see what is broken.
With out having the carbine in hand, it would be hard to see what the problem is. These guns are fool proof and hard to break, so my guess is that it’s something pretty simple. Might be the breech bolt is hung up on a loose cartridge guide. Is the screw in the locking block tight? Hammer screw looks fine, from what I see in the photo. If any of the screws that hold internal parts have backed out, the action will not work properly.
The long hammer screw is probably out of a model 94. The model 92’s hammer screw is identical except just a bit shorter.

Erin, I have a spare hammer screw if the original one is broken, so parts aren’t an issue
win4575, The bolt will move forward about 1/4″ before coming to a hard stop, so something inside is jamming the action up. I removed the screw and pin holding the finger lever to the locking bars, and while there is play in both, I could not get the bolt to move any more than it does now.I can use a 90 gegree dental pick to move the cartridge guide up and down freely, so that also appears OK. The loading gate can pe pushed on, and spring tension appears normal on it.
All of the screws externally appear to be seated properly, with the exception that the far end of the hammer screw is sticking out further than on my other carbines. I’m thinking about clamping the hammer spring and removing the screw to take the tension off, but am reluctant to do so with the hammer cocked and the spring under maximum tension. I pretty sure that if I can get the hammer spring and the hammer out of the way, I can get the bolt closed and the gun apart to see what’s broken. I suspect the hammer screw is broken, as everything else appears fine and there just aren’t a lot of parts in there.
Update – I do not think the hammer screw is broken, because if I turn the screw head with a screwdriver, the opposite side of the pin rotates in proportion. I had something similar happen several years ago with a ’92 rifle in 38-40, except the action had locked closed. That turned out to be a firing pin that had broken in two places, with the middle piece of the firing pin falling into the hammer and jamming it up. That does not appear to be the issue here, as when I push on the rear of the firing pin the tip pops out on the bolt face.
Had a similar situation with a friends 1892 trapper having a froze bolt. The bolt was froze because somehow the two inlets for the base of the ejector were bent or the staff supporting the ejector/spring/collet was bent. Not sure how or what caused those parts on the bolt to get bent but it caused the lever to bear against the bolt (if I remember right) keeping the bolt from opening all the way, froze. Dissassembled the bolt and straightened the parts, smoothed them up a bit and it worked fine after that.
I would try backing out the hammer screw if possible and release the hammer to take the tension off the mainspring if there is no possibility of getting the mainspring screw out.
Also, dont think its possible, but check the ejector, bolt, & lever to make sure its for a small caliber versus large caliber
Large caliber at left, small at right
I also see some wear on the finish next to where it bears against the locking bolt and where it enters into the receiver the right side of your lever, maybe your lever is a little bent causing it to bind or deflect with/against the bolt parts.
