Are the stainless barrels (Predator 16 inch light varmit, for example) chrome lined?

Thanks

That would be no!

I've wondered, why?

The barrels are made with a T416SS alloy . 416SS contains about 14% chrome as part of its composition.

Stainless steel is "stainless" (amongst other reasons) due to the amount of chromium already in the allow.  Chroming chrome wouldn't provide any positive return and would just cost more to make and sell.

unless there has been a change in materials RRA uses 410 SS not 416 SS

Martensitic Stainless Steels

Martensitic stainless steels are also based on the addition of chromium as the major alloying element but with a higher carbon and generally lower chromium content (e.g. 12% in Grade 410 and 416) than the ferritic types; Grade 431 has a chromium content of about 16%, but the microstructure is still martensite despite this high chromium level because this grade also contains 2% nickel.

410 is the base of the 400 series nonferrous series.
