Thread: JW15 firing issues

A friend of mine has a JW15 that won't fire anymore. I have had a quick look at it and this is what I have found.

Firing pin makes a dent in the rim of the cartridge but not as deep as my old JW15.



The dent is a funny shape, not a sharply defined one (one dent from old rifle and the other two from this one)
The firing pin looks like it might have been chipped? I haven't got another to compare it too.



Everything else functions as it should, am I on the right track thinking it's a broken firing pin resulting in it not setting off the round?

Think your on right track. Dry fired bit too much perhaps?

Maybe, it's pretty rough all over this on. I might give it a good clean up inside the bolt body and see if anything changes before I go ordering parts.

Will your bolt function properly in his rifle and vice versa??? Definitely eliminate other possible issues if they do.

I don't have mine anymore so can't compare unfortunately. I cleaned all the crud out of the bolt, action and chamber. Haven't tried to fire it yet so I might try that next.

The firing pin spring might be tired? That firing pin still looks wrong to me though.

Father in laws BRNO stopped firing, I disassembled the bolt and gave the firing pin slot a good clean. It went well afterwards.

Those pins have a flat chisel end which can catch the brass when damaged. File or stone the edges of the pin so the end is radiused on the sides of chisel end. Do not shorten the pin, just dress and polish the edges.

I'll try that before I fire it and see what it looks like, cheers. There is a slight depression in the center of the firing pin that is making me think it's too short already. I'll give it a go and report back.

Yeah this one was loaded with crud, nice and clean now.
