SKS people, beware of the stuck firing pin problem. This is a good video to help prevent this failure from happening to you. YouTube - SKS slam fire + the cure
I installed those in both of my SKS's. The first one I got had a firing pin the would stick like that. I had to soak it in Hoppe's for 2 days to loosen up all the junk in it.
I have to order some parts for other guns next week, I think i'll get a could pin to. Seem like all my guns break down all at the same time. Thats OK, I can Fix em!
For more info on the SKS go to www.sksboards.com every thing you ever want to know is there .
for the fireing pin fix go to the sub called Murrays guns as he has kits for the fix or send it to him to do it.
