Whats up with my Mosin Nagant?

Sounds to me like this. Either the spring is overly tensioned, or one end of the bolt is hanging up after the pin is dropped. Check the screw, and add a dab of gun grease to each end of the bolt.

ok I just bought another mosin at the recnet show here. while cleaning the cosmo off I have gotten a coule of metal slivers in my skin. maybe you have one of those


but I thought about this post when I was cleaning the bolt on it and checking it's cycling. if the firing pin has been dropped(fired) when the bolt is opened it recocks the firing pin back into a ready to fire state. this will be easily observed by watching the part on the back of the bolt go in when the trigger is pulled, and when the bolt arm is pulled up the back of the bolt comes back.

if the bolt has been fully disasembled and cleaned, I would check for rough edges, burrs, metal slivers etc. the process of machin when these were made was not as refined as how things are made now in the 21st century.


hope this gives some good insight

PROBLEM SOLVED Gents...thanks to all who chimed in. I shot the rifle Sunday,came in and started cleaning it,took all apart and tried to see what was wrong. Apparently, I had overtightened the reciever screws,and the bolt was actually catching on the mag assembly,or something. Anyway,when I re-assembled it,all was well. And,yes,Ive seen those metal slivers on other MN's.So,dont cinch those reciever screws too tight!
