View Full Version : AR-15 A2 Stock Removal

January 26, 2011, 07:11 PM
OK here is my question which to many will sound stupid. How do I remove the stock?
The spring and tube are out now I want to take the stock off to replace it with a skeleton stock. And if it matters its a DPMS Lo-Pro
Thanks in advance.

The top butt plate screw extends into the back of the buffer tube.

Thanks emcon58. one more question how do I get the buffer tube off? do I just unscrew it because it doesnt seem like it wants to un screw

Yes, it unscrews from the receiver. But watch out for the spring-loaded buffer detent.

Once you unscrew the tube a half turn, the detent and spring will shoot across the room.

To keep that from happening, I put my left thumb over the detent and unscrew the tube with my right hand.

A bit to add...

When removing the stock assembly from any M16/AR15 series rifle, take care to observe the following:

1. Get a properly fitted screwdriver. The stock screw has a very shallow groove. If you "skip" the bit out of the slot a few times, it will strip out, and will be very hard to remove.

2. When removing the stock, have the rifle or lower receiver facing straight down, with the stock up. After you break the rear screw loose, maintain light pressure on the stock until the screw is completely out. Then, lift the stock straight off of the buffer tube. As this is done, LOOK at the right side of the receiver that has been uncovered after the stock is removed. You will see a small diameter spring.

This is the detent spring for the rear disassembly pin. There is a small pin under the spring. This keeps the pin in the receiver when you disassemble it. Make sure that the spring is properly compressed into the detent's hole when the stock or plate is installed. And, don't lose that tiny pin!!!

What skeleton stock are you installing? The reason I ask is that some skeleton stocks such as the Ace ones you leave the buffer tube on, the foam tube goes over it.

Its an ACE stock and I realized that the tube stays on before I took it off but, how about sliding the foam over the tube? Anything to put on it to make it slide easier? Something that wont breakdown the foam?

I've installed 3 now and I just took my time and worked it on. One it was a real bear to go on and another it just slipped on. I think I read on midwayusa's review section that some people used a little WD-40. You may want to go there and read some of the reviews as a few of them explain how they got it on.

I had the butt stock off of my Colt for the first time last night (to add a spacer). Just when I thought I was in trouble, the factory thread lock broke loose.

Now, I have a fresh question: the factory screw is hollow, the replacement isn't -- why the hole -- a vent, oil, or what?

Closest I have come to an answer is that's it's a drain hole for letting any water that may have accumulated in the tube drain out. Don't forget these things are meant to be outdoors in all weather. Not having it there (the hole) doesn't seem to effect the operation of the rifle in anyway, at least not in the three I have put an Ace stock on. But it does seem that the tube may collect water, especially if the rifle was standing vertical in the rain or after crossing/falling into a body of water.
