SKS's are nice to own and you can find a ton of websites to dress them up (cheaperthandirt.com,gunbroker.com,Galaniti.com,Firestorm.com,ect) but your kind of limited to the type you have and if you live in the usa what state and state laws. In California, if you put more then a ten round clip on anything its a felony.Be aware of what the laws are and you can find some good stuff cheap. What you really are going to want is to expland your collection. Get some sort of AK knock of (sar-1) from romania, they have so many add on's you can almost put it in the M-16/Ar-15 catagory. Then last pick up a Krinkov (its the shortend pistol version of the AK) all the slips on the AK and Krin can interchange as well as most 75 round drums. You can find some nice mags and supplies pretty cheap. The hard part is getting ammo. Currently if you check websites and call around 7.62x39 is very hard to get and (due to the current middle easy usage) getting harder. Wolf industries is the main supplier and if you can find 500 and 1000 round blocks grab as many as you can afford.Firestorm also has a add on replica 240mm grenade launcher that you can attach to shoot flairs such. Its like a new toy there is really allot you can do.
Oh and adding a scope to a SKS is fine but the problem is accuracy. Most SKS's are shitty after 400 yards so if you going to do any long range stuff buy a bolt action 308 and a nice scope (leaupold) both will set you back about a grand each but you will get 1' MOA.
Good luck and don't shoot yourself..
