Title: Re: Cryogenics
Post by Whig on Jul 3rd, 2019 at 8:55am
I have a few JP Enterprise AR-15s that have cryggenically (cryo-accurizing) treated barrels. They have done this routinely to their barrels for many years and are known for heir advanced accuracy. JP Enterprises and Wilson Combat are my two favorite firearms companies for accuracy and extremely well built firearms.

I have shot tens of thousands of rounds through both companies' ARs and love them both. They both produce sub-MOA ARs with great dependability.

So, I think there is more than just the barrel that makes a great rifle. The cryo-accurizing may add to this accuracy and long-term dependability but I don't think it's exclusive.

I shot thousands of rounds of Russian steel (Wolf) ammo through one of my cryo treated barrel ARs (JP-15) rifles years ago when I was doing a lot of training during the ammo shortage. I bought a pallet of this ammo directly from the manufacturer and provided many of our club members (and me) ammo for those lean years. It caused a crazing of the bore of the barrel in a strange way and JP Enterprises examined the barrel and replaced it at no charge. They said that the steel ammo somehow caused excessive heat damage to the barrel and caused the early damage. It was many thousands of rounds shot and often 2-300 at a time, so, I don't know. It may have been defective in some way also. But, I talked to John Paul directly about this (JP- the owner) and he advised me only to shoot brass ammo in his rifles because of heat issues. It is one of those things- why spend more money for great quality rifles and shoot crappy ammo.

I have followed his advice since then. I didn't reload .223 back then and have done so since.

I don't know much about the science behind this process. JP Enterprises may have some info on their website.

Hope this helps.
