Yes, that is where the recoil spring goes, push down on the detent and shove the spring into the tube
No. A standard AR15 has a buffer tube that runs inside the stock that contains the recoil spring.
Yes
It depends.. if you have a carbine length barrel and will be using it on a rifle with a carbine length barrel, then yes. If you took it from a rifle with a rifle length barrel, and are putting it on a rifle with a carbine length barrel, then it won't function properly.
No.
The stock and forearm were traditional wood, but can be other materials. With the AR15 and M16 rifle, they are made from metals and plastics.
I put them on my 95 JGC 4x4 stock but they will rub when you turn. I put 2" spring spacers on mine and that took care of the problem.
On the AR15/ M16, the spring is retained by the buffer. The buffer is retained by a pin located at the lower outer edge of the extension tube.
You break the gun in half (with the screws of course), remove the end cap that keeps the bolt and spring in the chamber, and replace the end cap with the stock.
Wisner's stock them.
the ticker symbol for Poland spring water is psw.
"To put a lot of stock in" something is to trust its source.
