Not just the stocks make it more difficult to take apart and clean but the full length rails that are really popular make is a bit of a pain to get it apart and clean it. With non-corrosive ammo it's not a big deal. Boresnake, wipe bolt face, and done. So, if I were to tactical an SKS again, I would commit to just using non-corrosive ammo. You can make it work but it won't ever be AR easy to clean. The best mod for the SKS is the bolt mod and the trigger guard mag release. You can fire rounds out way faster than anyone using charger clips ever with just 5rds.
