Change Year - Attaching the Bayonet

[Matchka]

Local debate.  Ze questions:
Is there a specific year (and factory) that the rivet first appeared?
Was the change universal, or until a factory ran out of parts?
Would all Type 56's, with the rivet, be classified as 'commercial', for export?
TIA

I have two pinned barrels SKS with that rivet holding the bayonet in, they have the serial sequence I assume that is like the SKS-M, NR, Sporter, etc. One is C13 91 27938, other is C9 91 30029, both MADE IN CHINA BY CGA, IMPORTED BY GLNIC LA.CA. With that "91" I assume they were sold in 1991. The bayonet rivet is not flared so I can back out the rivet and remove the bayonets (on both rifles) The 9127938 was missing stock, magazine, the 9130029 was in the black monte carlo stock, replaced that with a wood stock and handguard (non-serialized) I forgot: only serial numbers stamped are on left side of receiver, bolt carrier and bolt, the trigger, receiver cover and magazine (stocks also) are not stamped with any serial numbers.

IIRC, the riveted bayonet idea came around the time that China decided to try a removable bayonet, which had a totally different bayonet handle, and a hook at the normal bayonet screw hole on the bayonet itself, allowing for it to be tipped out of the rivet permanence.

Using some of the parts involved were when I think when the confusion over what to do to keep the Clinton clan happy before the ban may have lent to some of the later imports sporting the permanently fixed bayonet. It was a confusing time when we were expected to believe bayonets made drive by shootings more menacing....despite any statistics to show bayonetting being a thing in thug culture.

Experts might chime in to correct me, but I just came back from a mini vacation...and I missed this stuff.

My SKS-S has the riveted bayo attachment. It was imported in '92, not sure of DOM. All late model features.

As with owenj492's examples, the rivet was never flared. Maybe it was a "quick-detach" idea for the ban era?  I probably shouldn't say that. That's how the internet lore gets started.     

Not much help for ya, Matchka. But it's the only info I can offer.

Thanks for the inputs. I've searched other forums, the interweb in general and Yooper - no joy wrt specifics on this subject.

Found another pinned barrel SKS made in China by CGA with serial C5  9101857 and the bayonet rivet looks to be "flared" see pictures below (found on proxibid.com):

Interesting topic.

I'd always assumed the riveted bayonet was a commercial modification.

Not sure if RunningMan could cull out the riveted bayonet entries on the SKS Survey to help on this query, or not? That would probably be the best way to get a perspective on the timeline of the riveted types. IF it's possible for him to do that. Ahh, RM can do anything! Right RM?

There are surprisingly few riveted bayos in the survey:

250000xx   Triangle   326
86753xx   Triangle   366
3915xx   Triangle   0130a
15042xx   Triangle   306
91278xx   Text Only / No Stamp   

I don't believe the /130a\ entry, the photo shows it didn't have a bayo attached.  Also the /366\ entry has bizarro S/N, likely a gun built out of parts...

Not that many reported riveted bayo guns. And they were all non-/26\ guns.

I looked through some of my past-owned SKS' and found an oval (926) arsenal with the rivet (25mil SN, pinned barrel), a DIG-import (pinned barrel) that was imported in '91 that has the rivet, and my previously mentioned SKS-S, '92 import (pinned barrel).

Both of my BETA ARMS-imported SKS-30's that were imported in 1988 have the rivets, of course. They were the first to use the rivets for the quick-release bayonets.

So the rivets date back to at least 1988 but were only non-/26\ arsenals, that we know of, to date.

Thanks to "firstchoice" for seeing that I had the rivets inserted on the wrong side and they have been corrected!

Wrong way:





They are supposed to be inserted on the right side, above picture they are inserted on the left side, the correct right side is flush with the head of the rivet, left side is not flush.


Correct way:

Looks good, owenj492!  Glad I could help.  The recessed rivet head definitely looks better when seated properly.

Your two GLNIC-imported Type 56's are really nice examples!

Thanks!!!!!

Excellent study/analysis so far. I've never seen a /26\ with a rivet. If '88 is the earliest date, at least that we know of; would it be safe to assume that all rivet SKSs are commercial?

[firstchoice]

Everything that I have seen so far indicates they were used only on commercial SKS'. Although, as with all things SKS, I wouldn't be surprised for an as-issued Type 56 w/riveted bayo to show up and bite us. 

At this point I think it's a pretty good assumption even with the limited data we're using. But assumption is the key word.

I forgot about my K Sports "DP" serial number 2300368P that is pinned barrel but has screw instead of a rivet:

Looking at owenj's DP... screwed v pinned barrel - didn't consider that.

Hey Owen, could you possibly post a pic of the other side of the rivet? How did you anchor the other side?I'm assuming it gets peened somehow) I've got one to do but I've never actually had an SKS with a riveted bayonet before.

[Larry D.]

Anyone got a good picture of the rivet by itself?
