Refinishing high end barrels

[EmanP]

Can you refinish Noveske/LaRue/PacNor/etc. barrels without a detriment to accuracy? I know LaRue Ionbonds thier barrels but can it be done after the fact without causing issues? Is the barrel extension then refinished to and would it extend the life of the barrel?

I can't speak on the ionbond process but parkerzing takes place in a phosphate solution held at around 200 degrees F, This is not enough to affect the metallurgical structure in a way that will impact accuracy. There are also bore plugs available to protect it during the process.

Add a 1 to your 200 and that's the temps we're talking about here.

how do you want to refinish it? Parkerizing is simple and you plug the barrel during the process so there's no degrading it. Bluing is done on high end barrels such as Shneider and Kreiger all the time. So I would say you're safe. High end barrels are always machined then finished, when it comes to say long range rifles they're finished after they're attached to teh action and baked often

If you're worried you could always go with a duracoating option

If you are wanting to extend the life of the barrel only alternative that I am aware of is Salt-Bath Nitriding http://bulletin.accurateshooter.com/...-is-impressed/

Ion-bond is an exterior treatment they do not treat the bore as far as I know.
Parkerzing is also a exterior treatment that does not extend barrel life.

I have a Noveske SS barrel that was done by Springer Precision in IonBond .

It is the pinnacle of perfection!
