Mossberg 351K problem



Log in to see fewer ads
I picked up a Mossberg 351K recently. It was functioning and feeding fine but was misfiring a lot, so I dissassembled it and cleaned an awful lot of crud out of it. The firing pin was a lot blunter than I thought it should be so a few minutes of jusidicous stoning to make it more pointed and back together. Everything seems fine.

It fixed the misfiring problem, that's for sure, but now when I manually pull the bolt back, it coks and fires just fine, but when fired, it ejects the spent case and feeds the next round and I can look in the side and see that the hammer is back, but the trigger is still dead spongy and won't release the hammer. I have to manually sysle it to kick the live round out, then it'll fire the next one but the same thing happens.

I'm sure I did something wrong reassembling it but have no idea what, everything seems to be in order, the rifle feeds and coks, just doesn't seem to be telling the trigger.

Any suggestions?

The first thing...

The first thing I would check is to see if the trigger is in contact with the trigger guard. When that plastic trigger guard shrinks, which is a common problem, the trigger cannot reset properly so it doesn't work as it should. Check that then get back with us to tell us if that fixed it.
God Bless, Frank.

Also if the 351 is like the 151's there should be 4 nibs on the feed tube. These need to locate on the 4 recess on the receiver. . The trigger slot needs to fit on the sear pin . Possibly just an alignment problem!

Thanks. I think I have it figured out, figured out that it is indeed cocking, the trigger return spring is apparently weak. When I manually push it forward after each round fired, it works as it should. I ran out of time yesterday, but when I get a few minutes, I'll pull it back out of the stock and see if I can bend that spring to give it a little more tension. Worst case, I'll replace it.

Before bending springs etc. Use a yellow wall anchor in the chamber and test fire when you have the action out of the stock. If that works then it is not that spring. I too have had problems with the trigger guards. - Bill
