I'll probably get banned, or horribly flamed, but I would like to recommend another SKS board to you all. ( Assuming that you don't know about it already)
Survivor's SKS boards
There is an unlimited array of important information on the SKS, and any problems that you may encounter with an SKS. Hope this helps!?
If the moderators do not like me posting this, please remove. I'll understand.
Great SKS site. Got all the info i needed to make my 1951 Russian Tula take detachable mags legally there.
