We had been kicking around the idea of different treatments or coatings for our 10/22 barrels and decided on Nitriding. This produces a lustrous black barrel that has a surface hardness of 70-75 RC, bore included. That is on par with chrome lined barrels !
The first batch is just back and in the shop, we have both 12.5" and 16.5" fluted barrels. I will be adding them to the website shortly (once we figure pricing). As well, you will be able to have this as an upgrade if you order a complete DAR-22.
*On a side note, we also had some of our CZ-858 replacement barrels nitrided. These are the same ones we use to convert Restricted -858's to NR. Now you can have a Non-Restricted -858 barrel conversion and know it will last for 10,000 rounds or more !
