The next step of the conversion is to take the Handguard off, there is one(1) screw on the bottom of the receiver in the front that holds the handguard in place, unscrew it. Now the handguard is on there pretty tight, I took a small rubber mallet and TAPPED the handguard towards the front of the barrel and pulled with my hand....it slid right off.
Next you need to take the gas tube off. This can be done by pulling the gas tube lever on the right side of the rear sight block up....I had to use needle nose pliers because it was very tight....I also put electrical tape on both sides of the pliers teeth area, to prevent messing up the finish. That part is up to you. Once you pull the lever up look right about the gas tube and you will see a little lip almost, that lever turns a piece of metal, make sure the piece of metal is flat and you can pull the gas tube right out.
This picture shows the end of the gas tube where it goes into the front of the rear sight block, notice the top where it's angled, that lever when down moves a piece of metal to hold the gas tube in place. When you pull the lever up it will look exactly like this picture, then just pull the tube straight up and it will come out.
Next you have to take the buttstock off, there are two(2) screws on the top of the stock, one(1) outside the receiver, in what is called the rear Tang, and the one(1) inside the receiver, unscrew those. Then there is one(1) on the bottom of the buttstock, outside the receiver, unscrew that one also. The stock is in there tight but I just smacked my hand on the bottom of the stock where you would hold it a few times and it came right out.
