Since I am slowly going into SKS's again I wonder whom is the guru on proper cleaning kits of rthe eras of the SKS military production and slings as well. I'd like to put them in my rifles and find the proper kits for their year/origin. Also the proper type of Sling for a russki SKS...that is other than the akm SLINGS THAT CAME ON THE RUSSKI IMPORTS IF POSSIBLE.
