sks light primer strikes

[greyling22]

my brother's norinco sks has a lighter trigger pull than mine. it also has a bit of a problem with light primer strikes. I have no idea if either trigger has been worked on, they are both used. he's shooting wolf black box ammo, and some cheap stuff in a red and blue box from cheaperthandirt bought a decade ago.

any ideas on how to get his sks working 100%? new springs? polish something? bad ammo?

I would try new Wolf springs. Also look at the ammo. I had some surplus .308 that had hard primers, took two tries to get the to fire in my FAL. First time there was a very shallow dent in the primer, second try they fired just fine.

The sks hammer springs wolf have are reduced power. I have had problems in the past their sks springs with light primer strikes. I would just get a standard sks hammer spring. You can probably get them at e-gun parts. Mark

taking appart the sks trigger group is possible, have a press, a vice, some punches, rubber mallet, and some patience.

First I would try cleaning everything really well (Before spending any money). If it hasn't been mentioned try using brake cleaner (non-chlorinated). In my experience is works well, damages nothing, and cleans parts really well. Of course, test it on a hidden are to make sure it doesnt damage the finish, and oil well afterward. I have used this on many guns with no problems, including a norinco SKS.

my sons friend brought his chi-sks to go shooting with us and tells me that he needs to replace the firing pin because he gets a lot of miss-fires (mostly light strikes) so I take it apart and hit it with crud blaster (same thing as brake cleaner), then CLP, we take it shooting and he doesn't have a single light strike, more than likely still had cosmoline in the firing pin channel.

Be sure to clean that floating firing pin really well also! You dont want any slam fires. "The firing pin should move freely and not stick forward, Its best to use military surplus ammo, as it has "Harder" primers." - I learned that here on THR.
