the cover mounts do not hold zero, and the tapco handguard mounts are no better. Check out B.C. Tactical for their scout mount. For $50 its the cheapest and easiest to install mount that will hold zero. You will need a micro red dot for that though. Next choice would be a choate mount, drill and tap 4 holes in the side of the reciever to bolt it on. Read thru the SKS optics sticky for info on pretty much all the available mounts and some home-brew setups as well
