First off, remove the buffer and buffer spring. Check and see if the retaining nut is staked on. Once you have the retaining nut loosened a bit SLOWLY slide the retaining plate back. There is a small spring at the lower right hand side (looking at the rear of the rifle, as if you were shooting), that will shoot across the room if you take the plate off to fast. This is for the rear takedown pin detent. Once you have the retainging plate backed off and the spring secured slowly rotate the whole stock counter clock wise to remove the buffer tube. Again there will be a spring and detent that will go flying across the room if you do this to quickly. This is the Buffer detent. Once that detent and spring is secured, the buffer tube should unscrew and you are halfway home.
