Mossberg .22 not firing

[DudeTotallyKyle]

Hey everyone.

Today I went to Georgetown Fish & Game and shot my Mosin and attempted to shoot my .22.

It was feeding fine... But when I cocked it and pulled the trigger, nada. Nothing happened.

I dry fired it MINIMALLY before today, and it seemed to work fine.

I just wanted to ask if I should take it to a gunsmith, or try to figure it out myself. I have 200+ rounds of .22lr that I want to shoot.

Thanks a lot for looking... I hope I can figure this out.

Did it click when you pulled the trigger? We need way more info.

It used to before today... now it's not clicking when I pull the trigger.

What model is it? Semi or bolt?

If it's not "clicking" it sounds like it's not cocking. Is the hammer locking back? We will need more info like the model and whether or not it's a bolt of semi like Ron said.

It's semi automatic. 15 round tube mag. Model 151M-B (I think?)


When I cock the bolt back, it chambers rounds fine.

Have you taken it apart lately? If not you might want to in case the spring broke. If it doesn't click it shouldn't be a broken firing pin.

Here are the disassembly instructions for a 151M. The only difference between a 151m and an M-B are sight changes. Pay particular attention to how the spring is situated. It is common to be assembled wrong and my favorite part is I can buy them cheap because they don't work.

UPDATE: Went to the range today with Dirtypacman and we messed with it a bit... It feeds rounds fine.. We even got it to fire ONCE... but that was it.

So I'm puzzled as to why it shot ONCE but only once. Going to try to take it to have someone look at it this weekend.

Broken firing pin? Maybe it's still protruding just a little, or maybe its in there, but broken.
You can lift the firing pin without removing it. Try not to push the firing pin past the staking if you don't need to remove it. You can see the stake marks in the last picture.

It should have a beveled end and it only protrudes about 3/32"-1/8" when the bolt is closed.

Here is the complete bolt.

Those old Mossberg semis are notorious for breaking firing pins. Find a local guy who has a garage full of parts or maybe Numrich has them.

You can get all the replacement firing pins at havlinsales.com, among other parts. I have a lot of Mossbergs and the only one with a broken firing pin was bought with one.

Okay I'll keep that in mind. Thanks guys.
