Hello. Ive been doing a little research on a rifle I have purchased, and not yet taken possession of.
Zastava M85 7.62 x 39
From what I have read they are considered a "modified short action mauser" type.
Im wondering if anyone has any experience with changing striker springs in these ?
would a 98 mauser higher lb spring work if you just shorted it to the length of original spring?
Looking for options...
Maybe shim the spring to increase the pressure?
**Edit. this is to rectify light primer strikes when using mil surp ammo**

Thanks
Dave

let me know how it goes.
i have one of these, and would like it striking a bit harder.
right now it fires modern ammo all the time, but milsurp only 80%
 
Mauser 98 springs won't fit these.
Found this from the net.

**Tried a "stronger spring", shimmed the stock one, got a new stock one and none made any difference. Problem is simply a very light weight striker assembly and a very short lock time (distance firing pin travels from sear release to impact primer. Just not enough momentum there to pop hard primers.

Every hard milsurp primer or reloaded one that wouldn't go bang after repeated strikes from my Mini MK X went bang just fine in the SKS.**

**Remove the bolt and drop the FP so the FP protrusion can be checked. It should be somewhere around .064" If it does not measure correctly then you have either a short FP or there is something impeding its travel.**

Hopefully you ordered a bunch!! I too have light primer strikes, mainly on Norinco ammo or surplus. Commercial stuff Hornady, Winchester, American Eagle seems to be fine for the most part! 8 weeks will just make it before hunting season!
 
Thanks for the reply! Wondering if we are sure that this will fix the light strike issue? I have read places that it can be due to short firing pin protrusion.
 
I have one of the Mauser Mark X rifles that came into Canada around 15+ years ago. They are the same rifle as the M85 and made in Yugoslavia as well. I have never had a failure to ignite or delayed ignition with this rifle. It doesn't matter what I feed it.

My only issue with my rifle is that the chamber is a bit to generous. It's another project on the to do list. Set back the bbl one thread and recut the chamber.

It's accurate enough so I haven't been to concerned about getting it done. It's also had an almost exclusive diet of different types of surplus ammo.

I had my gunsmith check my firing pin protrusion, it was a few thousands short! Even after he turned the firing pin to get the correct protrusion, I still get light primer strikes.

So that makes it sound like the stronger spring would do the trick then. I hope this is the case!
 
So I noticed that during my last trip to the range I had a lot less light strikes. I was getting maybe 3/4 light strikes before and this last time it was maybe 1/10...wondering if mine just needed some breaking in or maybe I was lucky?

I am starting to get excited about this gun working better, it is a lot of fun to shoot due to the cheap ammo and light recoil.
 
No issues with my Remington 799 which is a Zastava M85 barreled action in a Remington laminate stock -
