Hey guys, it's time to start one of those threads that ends friendships...
I have been pondering the benefits of all these new types of barrel linings...
In the last couple years I have started to see more and more non-chrome lined AR-15 (and AR-10) barrels. I seen terms such of Nitrided, Melonited etc....
In my quick research it seems that all of these methods harden the surface of the bore (and outside) and make the last few microns super hard. To the point that it is said that a nitrided barrel has a longer barrel life than chrome-lined. (it can also be done to SS as well)
It is also said that since when you chrome-line a barrel you must take a couple-thousands of material off for the chrome and that chrome lining is a chemical process that is imperfect that the nitrided barrels can be more accurate.
Now the thing that worries me is corrosion resistance... The swamps of LA are not friendly to exposed steel... I can find little evidence of the corrosion resistance of nitride...
All of the information I have seen has just said that is is better than bare steel but that's it... Anyone have any input on this?
