If you unscrew the brush, you might nick up the rifling with the steel rod.
That's why I use the plastic coated Dewey rods and keep them clean.
I can't see how a bore snake is any harder on a barrel then firing steel jacketed czech surplus thru it. IMHO... Just wash it every once in a while. Throw it in a old sock tie it off and fire it into the laundry.
I am sure you will mess the accuracy up more by dinging the crown with a 5 dollar steel cleaning rod.
Bad cleaning practices will indeed damage a barrel quickly. The reason that the boresnake is bad is that it is abrasive. The soft steel jackets are softer than the barrel steel, where the grit is harder and will cause scratching and wear. Your gun, your choice.
Considering how many rounds most people shoot and the general accuracy level of the SKS, either way will probably work fine for a long time. Personally, I will never use a boresnake on any gun I own.
