Extra hole on sks gas tube

[noahs ark]

Hey guys, love this section of CGN just dont post in here as i dont have much expertise on the subject.

I just bought a third SKS yesterday. Tore it down right away to take advantage of the 25 degree weather we've been having out on the coast to melt some cosmo out of the stock.
I took a look in the gas tube to see how caked it was and noticed daylight coming in, not the 2 holes that are supposed to be there this hole is not round and was caused by where it was notched out at the factory at the muzzle end of the wood hand guard.
Sorry no pics it's right in the 45 degree notch where tube becomes narrower. My other 2 sks' are 49 and 52 and have no hole there This one is a 54 laminate stock and hardwood handguard (refurb piece) I'm not worried about it coming apart on me just hope it doesn't rob to much gases when I get around to shooting it for the first time.

Has anybody seen this before? Common? How did it shoot?

I have one sks. It has this hole. This thread is my first reason to believe it's not normal. Hundreds of rounds, shoots fine. I figured it was relief after the piston travelled the desired distance.

Manys of my sks's have this hole, nothing wrong with that. Igor have been too happy with the milling There's no gas escape there anyway.

Now that I'm sitting here looking at it, I realize that no gases should get that far and just the traveling rod.
Thanks for pointing that out.

There was a thread on this same question just a short time ago. There are quite a few with this hole in them. Nothing to worry about. Directions: clean it, shoot it, have fun, clean it. Repeat liberally.

That would be my thread lol!

Is it a hole like this?



If so,it is fine mate!

 

[popcanhunter]

Gas gets that far, as there is a corresponding abundance of soot on the barrel after shooting

Yep, that's the one. Just a little disturbing when the other 2 were "hole free"
Thanks guys

I drill holes in mine to control the gases and reduce the violence of the ejections.

Interesting to see if this new rifle ejects a little tamer then the other 2.
One always shoots out and forward and the other straight out the side.

Plenty of camara angles please

Check the sks survivor forums there is a thread on drilling your gas tube to tune it to eject neat little piles at your feet.

All fun until you run across a weaker batch of Ammo haha also when the gun gets real gummed up its wont run as along as the cycling will be weaker

But to each there own, drilling holes to reduce recoil and keep brass is a great idea if it suites your shooting style

I've never had any issues with ammo.
