Thread: CZ452 stiff bolt

You might be checking for a fault at the wrong end of the bolt.
Look at the locking lugs too (handle end of bolt).
This link will show some pics at #4 post.
Might be your problem?

So I've shot another couple hundred rounds through it since I last posted about this. Sometimes the throat(?) Is taking small shaves of lead off some of the bullets. This of course leaves some stuff around the edge, as shown in this photo.




Anyway, it seems the bolt face has been accumulating stuff around the edges too, which is probably the main reason for the stiffness. It seems to be working okay now, I'll just need to check it and clean the bolt face more often I think

Oh, it's the rear opening of the rifle chamber... I thought it was a photo from your astronomy telescope of a stellar black hole at the core of the Milky Way galaxy...
