Yes, it's chrome line barrel, the tube is commercial and yes, you can remove the stock and replace with folding tube, can be bought from co-winarm. Hope it help.
Ive also shot 3500+ corrosive thru my first 858, and i dont even clean it as much as i should, its more of a game to me now as to when it will fail haha.
You must be very patient haha. I second using wipeout for the 858, its so much easier and prevents corrosion. Just remember to plug the gas block before filling the bore lol.
supernova, what are you using to plug the gas block with, cork, cotton balls what???
C/L barrels *ARE* available on N/R Vz. 58s.
You have to specify that option, and it adds ~150 bux to the cost.
