Howard,
Not to take away from members of this forum but go to http://www.ar15.com and ask the same question. It is also a great forum for other questions you may have as well.

It's not hard at all
Howard,
Get a flat screwdriver and remove the screw in the top of your A2 buttstock. When the screw is out, carefully pull the stock straight back away from the receiver. Do this slowly as there is a small spring that holds the rear push pin detent on the right side of the receiver that is held in place by the stock. As soon as you pull the stock far enough away from the lower receiver, catch the spring and put it aside. It's not under a lot of tension so you don't need to worry about it flying across the room, just be careful with it. If you have to twist the stock on the extension tube to get it to come off, there is a danger you may pinch the spring and ruin it.
Once you have the buttstock off the extension tube, tilt the receiver so the front is up and catch the rear push pin detent and put it aside with the spring.
Now depress the buffer retaining pin and remove the buffer and spring from the tube. Place them aside. Now you are ready to remove the receiver extension tube. Remove the spacer that is on the back of the extension tube for the A2 stock. Now put a wrench on the flat on the rear of the extension tube and unscrew it. Many times these extension tubes are installed with Lock-Tite into the lower receiver. If it won't break loose holding the lower in your hand, you can get a lower receiver vise block and place the lower in a vise. Don't just put the lower in the vise, padding the jaws with a rag or you may damage it. If you don't have a lower receiver block for your vise, you can use the following tried and true method. This method was posted to the AR15 List by rambo (noted Colt expert):
Take the lower into a room with thick carpet, place the lower on the floor and sit on it. You will be able to get enough torque to break the extension tube loose and the badding in your butt and on the carpet will keep you from damaging the lower. This isn't a BS story but an actual field expediant. I know it sounds silly but rambo swears by it and I've personally seen rifles he's used this method on, no damage.
Once you break the extension tube loose, carefully unscrew it. It holds the buffer detent and spring in and you want to be careful not to lose them. After you get the tube off, you are ready to install the mock collapsible stock. Using a little blue Lock-Tite on the threads start screwing the new receiver tube into the lower receiver. Put the buffer retaining spring and pin into their hole in the lower and screw the new tube the rest of the way into the lower receiver, being sure you get the end of the tube over the pin to hold it in. Now carefully index the rear of the mock collapsible stock so it's straight up and down in time with the receiver and it's nnot canted. Put the rear push pin and the detent and spring back into the lower and being careful not to pinch the spring, put the backing plate that comes on the mock collapsible stock against the back of the lower receiver. Now hold the plate against the lower while you screw the locking nut tight against the backing plate. Be careful that you don't cant the stock while you are tightening the locking nut. A little blue Lock-Tite on these threads is also a good idea. Once you have the nut tight, take a punch and stake the nut to the backing plate. Many people omit this step as it makes removal of the stock easier, but it's the only way to get a really solid mount between the stock and the receiver.
There are two types of locking nuts being used. One uses a spanner wrench to get into round holes for tightening and the newer one is a castle nut that requires a special wrench. One of these wrenches should be the only special tool you really need.
Put the new carbine length spring and buffer in the tube and you are ready to go.
