While cryo treating (as opposed to Cold Treating) works well my guess Is ArmaLite is right on. Both treatments affect unlike metals differently. I think before they or anyone jumped on it it might be wise you see if the metal you are using is responsive and provides 'which' benefits.

This came up in my discussion with Keirger and they do for stress relief before and after working the steel. I cannot remember if they do cryo or cold treatment.

Another thing they do or in this case do not do is straighten the bbl, its really a go/no-go. They work to an accuracy of .0001 and lap to 16 microinch, half the standard for National Match.

I cannot find a lot of support for cryo on bbls outside of stress relief.

ArmaLite always seems to be smart, very smart...
