Just got a new [to me] Yugo M48BO Mauser, looks great all over, though one thing... The bolt is acting odd... I can #### it, decock it, dry fire etc, it all appears to operate normally except:

- It is VERY difficult to change the safety, I generally have to use the heel of my hand to cycle the safety.
- Usually I cannot get the safety back on without having to cycle the bolt a couple of times then I have to use 2 hands.
i.e. If I have a round chambered and bolt cocked, there is usually no way to put the safety back on... !!
My other 2 Mausers [Brazilian & Czech] the only time I cannot engage the safety is immediately aftr firing [de-cocked] which I believe is normal.

So what is wrong here, what should I look at replacing?
A couple of clues maybe:
- It is VERY difficlt to break down the bolt & remove the firing pin, I frequently have to lean on it with my full weight. [it easily has 3 times the force of my other 2]
- the cocking piece does not rotate around the end of the firing pin freely or smoothly. It will bind and catch and some times requires a good amount of force. [once the bolt has been broken down and the spring removed, they are very clean - no goo jamming it up]

So, is the spring tension normal for a Yugo?
I'm suspicious of the firing pin itself, could someone have jacked an incrrect pin in there?

Or are these Yugos just beasts?

Looking closer at the firing pin... the Yugo is on the left, a Czech on the right... the obverse sides are identical. and the spacing of the rings is just slightly different.
