Sorry, I'm not up to date on SKS and AK barrels. I would assume that they were chrome lined because they are semi-auto rifles and the barrel will heat up pretty quickly with multiple rounds. The Mosin-Nagant was never chrome lined. It had a very short handled bolt that makes it awkward to operate rapidly. It was designed to be operated by Russian soldiers using their left hand. They would be hunkerd down in a trench or foxhole with the gun to their shoulder and sighting on the enemy. They would fire the weapon while mantaining their grip on the rifle stock, finger near the trigger with their right hand while reaching over the top to throw the bolt up, back and forward with the left hand.
This is a gun built in 1943 on a design that originated in 1891, the barrels were't chromed. The guns shot rounds with corrosive primers to such an extent that soldiers were issued a small divided bottle with a separate cap for each side. The solder got into a fight and as soon as he could thereafter, he poured the water or water/ammonia mixture down the barrel to nutrilize the corrosive nature of the primers, then he ran a rag down it with oil from the other side of the bottle. Some of them peed down their barrels when they had no water or ammonia. My ex-son-in-law should have peed down his barrel.
Ammonia is as bad as the corrosive primers. Put a drop of ammonia on the receiver and then check it a few days later. The idea behind windex was the soap and water it contained. Just flush w/ boiling water after shooting. Then clean.

My 1953 Soviet (Izhevsk) SKS was not chrome lined.
