Remington 760 Pump Action firing pin chipping at the back Any fixes??

Hello just wondering if there is a fix, or is the pin needing replacement? Any idea of cost for Replacment.

Thanks Derek

Picture?

It would need replaceing.

That’s the direction I’m heading, with replacement. Thanks Derek

I'd suggest that a replacement is pretty much coming due soon.

Depending on the condition of the chips, I would likely not be too concerned about cleaning the chipped area up and using a rubberized abrasive on a Dremel or similar to blend over the edges, and carrying on using it in the meantime, at least while waiting for a replacement part to arrive.
That it is chipping, is pretty much indicative that the heat treat was not quite right, and the metal was left too hard.

If worse comes to worse and you cannot source a new pin, a talented welder could likely add a bit of material there to work with.

Pictures tell the story though. There are chips, and there are CHIPS, eh?

Thanks for the suggestions I too thought about a small weld; but I think I’ll go with my original plan.

A weld might/will remove the heat treatment.

I've seen the firing pins peened over but never chipped. I believe the firing pins are the same for the 740/742 rifles as well. May have one.

Almost for sure.

But, given that the pin is currently chipping (way too hard) it's a viable option.

Given the number of construction nails used as firing pins in old guns, it seems to me that it'd take rather a long time to peen it over enough to cause any issues.
Plus, there is the option of using one of the tool steel fillers, that may just work as is. It's not exactly a jackhammer shank getting struck thousands of times an hour (minute)

But personally, since gunrunner100 seems to have one available, I'd be talking to him...
