SKS gas tube hole

Hi, im just wondering if I have to worry about a hole on my sks gas tube. It still shoots perfect, but noticed that it might have gotten a bit bigger over the past year. Thanks

Forget you ever seen it. There needs to be a hole/vent on each side of the gas piston as to not create vacuum or pressure. That side of the piston is gas-free.

Does this include the one at the base of the tube, near the bottom of the picture? I seem to recall all of mine not having that hole.

Yes there is a small round hole on either side of the gas tube BUT none I have owned have the hole as shown in OP's pic-weird?

Mine has it, it's normal.

I wouldn't be too concerned if it's still working fine, it's not like less pressure behind that side of the piston would be any danger.

Some have that some don't. It is caused by the production method used in manufacture. It does not affect operation at all. I have seen many with and without that hole.

That seems to be normal op, my SKS has it too and she works good. Don't worry, be happy.

Thanks guys for all your posts. My other sks doesn't have the hole, so I was a little curious. Both shoot AMAZING. Thanks again
