I have an early model J that needs a new firing pin spring. Unlike a Remington there is no cross pin through the cocking piece. Am I right to assume that the firing pin is threaded in to the cocking piece?

Should have mentioned that the shroud is the Remington style..

Are there 2 stacked set screws thru the cocking piece to the firing pin?

No there is not. I called "Defiance" today hoping Glenn Harrison could shed some light on things and he either could not or would not! It appears as though the firing pin is threaded in to the cocking piece with nothing to lock it in place unless locktite was used. I guess my concern is, how do I control the spring once I unscrew the firing pin out of the cocking piece? Make up some sort of jig to contain the spring? There does appear to be a couple of flats for a small wrench on the stop for the spring on the firing pin end.

Well damn. Can you post a few pics so maybe we can decipher this?

See if you can get hold of Chad Dixon. I think his company name is Long Rifles. A few years ago I was having some trouble with a Nesika K and Chad was the only person who was willing to help. He saved me a lot of trouble and solved the problem in a few minutes. He knows Nesikas.

softly in a non-marring vice, use the proper wrench on the firing pin flat and unscrew it.
It has normal right hand threads. I have never had one come unscrewed without loc-tite.

Glenn Harrison called me this morning and gave me the same advice. I suggested locktite and like you he said I didn't need it. The original spring was a little over 15 lbs. which is why I am replacing it. Nesika sent me two springs. One like the original and a longer one.

Appreciate the advice

Martin,

I am amazed there is not the double stacked set screws locking the FP to the striker head. I have two Nesikas, a J and an UNL "Fat Boy", and both have the set screws. I have also fitted barrels to many, and they all had the screws.

Regards,

This is an early J and as I stated earlier there are no stacked screws or set screws. It turns out that the firing pin is threaded in to the cocking piece and that is it! The serial number is J0118.

I'd measure the length of the firing pin to the shroud to make sure you have it screwed in to where it needs to be. May just bottom out and be it, but I'd measure it to make sure. Had a J years ago with the Remington style cocking piece. Always shot extremely well, but would have liked a little more extraction camming on it. Sold the action and have regretted it ever since. Sure easy to get too many benchrest rifles.
