Im curious if it was nitrided then chrome lined or if its nitrided after the chrome lining. If its the former I wonder what gain in barrel life(if any) there is to having a nitrided layer under the chrome. If its the latter I wonder if the nitriding process affected the chrome lining at all, if not then Im all for having the superior outside protection.

This is my first time seeing a barrel like this on the market and why didnt anyone try it sooner?

I was going to say that there is a typo in the description, but the barrel definitely looks like it has an SBN finish on the outside. I imagine if it really is chrome lined, the chrome lining would have been done after the salt bath. However, that poses its own set of difficulties with manufacturing, so...?

Reach out to SoLGW. You’ll get an answer pretty quick. They won’t hide anything.

CrN is really hard. It could be done either way, but im not sure which would be better, or if there is any advantage at all. The base metal is the same so erosion would not be changed.

Edit: after thinking about it, the extra hardness of nitriding the base metal would likely be better and lead to slightly extended barrel life. That said, i doubt its enough to matter much.

Sons of Liberty stated that it was a misprint and is not chrome lined and nitrided. The item will be turned off on the website if it hasn't already.

There's advantage to it, but it's an advantage that he may never realize or make it worth the additional cost. Unless OP is a bean counter for a large institution looking to buy barrels...

So, which part was a misprint, the nitriding or the chrome? (website still shows both)

Is sonsof liberty considered a good to go company? Looking for a new upper and trying to find if some of the smaller makers are considered upstanding.

They seem to be saying the right things. They’ve got YouTube videos showing how they do things right. Check out thier channel. If I were looking for a new AR I’d consider them.
