With all due respect... are you new to firearms or something? Never owned a semi-auto? Or...?
Not really new to firearms, I hunt for a living.
The gap in my expertise is that all I own are bolts(besides shotguns), I have never bought a used gun so they are typically accompanied with owners manuals. First semi, yes. Hence, my post about wanting to learn.

I bought this SKS because it looked like a fun gun to shoot, however in the last 24 hours I have become very attached to it.

I am going to get another one later today. I want to keep one looking like it does now, and one to put a different stock on so I can get it out in the field.
I have been reading the red rifles section as much as I can, I had no idea this rifle had such a following, and I am very pleased to see so much effort has been made to keep people educated on it.
Later, once the kids are off to school I am going to take every pin/screw and bolt out of it to see what makes it tick. I keep reading something about a gas cylinder, and I have no idea what that means.
Being new at something can be difficult, getting your head around the terminology can be a challenge. I will know as much as the rest of you soon enough, but right now I am on the bottom end of a learning curve.
I appreciate the help more than you know.
