SKS's are more accurate than AK's (not that that is saying much). Getting a mount that is sturdy and reliable is the most expensive proposition. Dust cover mounts are the least desirable method.
Check Ulti-mak for their Scout mounts. Maybe someone can chime in on their reliability. Simple BSA red dots are cheap enough to get one and a back up for less than $75.
In life, strive to take the high road....It offers a better field of fire.
