Random newb bayonet question. . .

[fchaus]

So I see bayonet referrences about screw-on vs rivet-on. I can figure the obvious about what/where the screw or rivet is but when were they used one vs the other?

[Phosphorus32]

Some of the late Chinese SKSs used the rivet. Most of them used a screw.

It's also only with Chinese spike bayonets, no other countries nor the Chinese blade bayonets used rivets.

Was is only certain factorys or certain serial#'s that had the rivets vs the screws or just random on the later guns?

[running-man]

No they are seen on certain years at certain factories.  The riveted bayonet is a very late feature on n SKS, only seen after year 25 or so.  For example in the arsenal /416\ photos below you can see that years 17 & 18 are screws vs 27, 28, & 29 which are all riveted.  Obviously a change there.  When you look at /26\ production, they used screws all through the entire (year 26) production run.  I guess it just depende on what subcomponents the factory was set up to use. 

One other thing: the removable riveted bayonet (like those seen in the SKS30) while prevalent in the commercial imports, I have not seen in any original military factory production run.

Jedi Joe-da. So much knowledge, he has.

Did anyone notice that 4 of the 5 pics have the bayonets upside-down?

Laugh. I didn’t. Don’t normally look for it.

I will say this, that year 28 gun is in a German museum somewhere.  Doesn’t say much for their curator!
