The other day, I was talking with a older fellow who works for a company called Rifle Tech. He has been a gunsmith for over 40 years and was talking about things way beyond my expertise. To make a long story short, he was telling me that the SKS Gas Tube his company developed increased the accuracy of the firearm by a good margin. He was telling me how the OEM Gas Tube was poorly designed and if it had been designed today, the engineers would have surly caught it. He was telling me exactly how much pressure would travel through the tub in a certain amount of time and that the stock gas tube and piston bends so much that when you watch it cycle in slow motion, you think it's going to snap in half. He then went on to say that after the very round you send through the rifle, the OEM piston will not be perfectly straight any longer. Most of the time, this cannot be seen by the naked eye and must be checked with a machine. The gas tube and piston Rifle Tech designed is heavier but it doesn't bend which is said to increase the accuracy of the rifle.

Has anyone ever heard of this? Does it sound right?
 
I suppose a very rigid gas tube 'could' work like an accu-strut on a mini. I find most sks rifles to have just fine accuracy for a nearly 70 year old design battle rifle. Especially when you consider the countries building them were not known for issuing match rifles to soldiers.
 
Sounds plausible but I wouldn't expect any miracles with open sights and surplus ammo. It might make a 3" gun a 2 4/5" gun. Those barrels are pretty crude and I am sure there is better money spent on other upgrades.
 
My sks's didn't shoot any better without a gas piston o in the case of a Yugo closed gas port.

This old guy is just trying to get you to buy something

For a rifle design that is 70 years old, I'd say it's held up fairly well. I only hope I'm functioning properly when I hit 70.

You could certainly do 'stuff' to an SKS to try and improve it's function, but it's still an old design. Not too much you can really do.
 
Yea, I kind of thought it might be a sales pitch. In that video though that Apple a Day posted, you can definitely see that gas tube flexing in the top down shot. You can see the entire hand guard lift up and bounce off of the stock. I'm just having a hard time trying to figure out how this would effect accuracy. You would imagine the round is already leaving the barrel when the gas tube starts to flex.

Watch a high speed video of an AK being fired and then you won't have any illusion as to how an sks is being shortchanged by its gas tube

Yea, I've also heard that's one of the reasons why the SKS is more accurate.
 
For a battle rifle the SKS is pretty accurate. Making major modifications to an SKS is akin to putting racing slicks on a 50 year old dump truck.
 
Hmm, seems like marketing to me. The gas port is not far from the muzzle, and I am not sure what the gas dwell time is on a SKS. I am not sure how far that piston moves before the bullet leaves the muzzle.

If Yugos shoot about the same with and without the gas port open, than I think this is more marketing than engineering.
 
Never believe the person trying to sell you something.

Contrary to popular belief the Russian's weren't that stupid, the SKS has quite a lot of really well thought out features, and none were by accident.
 
SKS was peasant-made for peasant soldiers, coming from the factory quite capable of reliably killing a 200 pound man over 200 yards away. Now, it kills 200+ pound deer and pigs quite well.

I don't care if my SKS' gas tube bends in action. It does what I need it to do, when I need it done.
 
The bullet is long gone before the gas piston even starts to move. Besides, there are two pistons in an SKS......chris3
 
Is the SKS with Tech Sights still such an unknown quantity? Two years ago it cost about $50 for the fully-adjustable version.

On several websites, they discuss the SKS as if the original sights are the only option.

No tech sight is pretty much the most 'shootable' (and best return) upgrade
then you have the aftermarket stocks.... but those, well, lipstick on a pig (does nothing and just annoys the pig)

When you say the stocks annoy the pig, are you saying that changing the stock causes malfunctions?

people do the stock (and many other even MORE pointless upgrades like a dustcover scope mount (think about it it ONE pin, NOT tightly fit, and it gets hammered every time the bolt returns, no matter how good the scope, it don't matter when the mount is shaky)

To make a SKS look Tacky-kool (as in it does NOTHING except looks...)
 
How exactly does the gas system affect accuracy? I call BS and he was trying to sell you a gas system.

Meh, I do indulge in the railed dust cover.

With the included buffer, it holds zero just fine, even returning to it when the rifle is dismantled for cleaning. It's only problem is how tight it is, which is a bear to remove, but a blessing at the range or tree stand.

So, I cannot agree with you here.
