SKS Ribbed for Her Pleasure?

[nate77]

Do all Chinese SKS's have ribbed barrels like this? Guess I've never noticed before.

I don't believe that my Norinco is, now I'll have to dig it out to check.

Thanks, I haven't noticed it on others, but I'm no SKS expert.

Mine does not... that looks like a machining error.

There, FTFY.

It goes all the way back, even under the stock.

If it is an error, it is cool, uniform, and unique.

This SKS has a pretty cool story too. I bought it off of INGO, the guy picked it up at a gun show in the early 90’s for $75.00, he never even took it out of the box, I’m the one that cleaned out the cosmoline when I bought it from him a few years ago.

They do not.. In fact I have never seen another SKS from any country like that JFYI.. Very Cool, Would help it dissipate heat ever so slightly.. Or burn that pattern into you're skin.. Gary/Hk New member here but not new Clarksville Indiana

 

[nate77]

Thanks for the insight, and welcome to INGO.

I used to sell SKS rifles, and noticed the rough machining that you show, on the Chinese commercial or "export" models. The surplus military rifles rarely showed the machining since, I believe, they were made better

Quick and dirty machining with a dash of "hoop stress". Still good enough for minute of man at a couple hundred yards.

Mine don't. Curious where that came from.

I did some searching around Youperj's SKS web site. The checkering on the base of the bayonet is basically universal, but I didn't see any with ribbing on the barrel.

Did find a couple of other mentions of "ribbed" or "radiator" barrels. Here is one thread. It is definitely unusual.

Thanks, this thread talks about it too, and gives an explanation to why it happens during the machining process.

Radiator barrels

It is just very uniform, and pronounced on my gun; like it was meant to be that way.

My MAK90 has the same ribbing. Does not look like a machining error/rough machining or unintentional. Not that I think it serves any purpose...

This will happen on any lathe turned part if the feed rate is too fast for the tool bit configuration. If you want a very smooth surface you can use a radius on the cutting edge of the bit. A sharp "vee" at the cutting edge will produce a good surface if the feed rate is slowed down. On your example it serves no purpose, just indicates they were running as above. The surface on the more expensive firearm barrels are quite likely "ground" instead or after lathe turning.
