So I recently bought a Norinco SKS. It's a good gun and shoots well.
So I'm doing a full strip-down of it, and when I take off the gas tube I had the rifle in my lap, pointed slightly downward...
The gas piston fell out and struck my kitchen floor. When I was putting the rifle back together I couldn't get the front head of the gas piston to enter the gas tube. Striking my tile floor put a small dent in the head of the gas piston, and it didn't have clearance in the gas tube.
Enter my dremel tool, and I grind off the minute deformed protrusion, and I get the gas piston to seat and travel in the gas tube. But it seems as though it might not be traveling as far back as it should.
So the gas tube's front 1/3 is an exposed metal tube, and the back 2/3 is covered with a wooden handguard. About 2/3 of the way back on the exposed metal portion there are two small holes in the gas tube. I'm assuming these are for gas bleed-off after the head of the gas piston has traveled backwards beyond these holes.
My piston head only travels backward about 1/2 the length of the exposed metal portion, and never gets to, nor clears, these holes.
How far does the gas piston move backward on a properly functioning SKS gas tube?
