chinese sks+ bayonets- it is when it was imported that is the decieding issue if they can have one. The one we picked up for Sue had one still in place, and I am reasonably sure it is okay as it is the vintage that was allowed to have them . (the earlier imports. ) and it was the deciding factor on her wanting it.
I swear this particular one has never been fired, still had alot of cosmoline on/in it. (and the cosmo was still in the fireing pin channel! Yikes. )
For those with Chinese SKS's they where soaked in cosmoline and some of the firing pins where stuck causing slam fires and in at least 1 case a death.
I pulled the bolt and yanked the firing pin and sure enough it was full of drired cosmoline. (I did this before shooting it) So If you own on and the firing pin doesn't move freely PLEASE drift out the retaining pin and take out and clean the channel and firing pin. the one in question was able to move but not freely.
