Changing out standard, two-piece handguards may be very simple for someone familiar with the AR-15, but the fact that a specific tool is made for it has caused me to consider offering instructions on removal/installation if only to save someone the cost of the tool! Honestly, this tool can make it easier to pull back the delta ring but for most individuals it is probably unnecessary. Pulling back the delta ring is where this task starts...
1. Separate the lower receiver from the upper receiver by depressing the takedown/pivot pins until the two halves of the weapon can come apart.
2. Secure the upper receiver in an AR-15 receiver vise block or place the end of the receiver against a firm surface like a bench or your stomach, and pull the delta ring rearward with one hand.
3. With the other hand, separate the two-piece handguards near the rear of the handguard where the two pieces meet. Often you can do this with a fingernail; if necessary, they can also be GENTLY and CAREFULLY separated with a thin tool (only do this enough to allow your fingernails to do the rest of the work).
4. Typically, the top piece is easier to remove and install first. While holding the rear of the top piece of the handguard, push forward towards the front sight base while lifting the rear of the handgaurd away from the barrel. Once it is removed, while the delta ring is still pulled rearward, push forward on the bottom piece and then pull away at the rear of the handguard.

5. To install a new, two-piece style handguard: insert the front of the top piece into the end cap behind the front sight base or gas block. Once it is centered (the gas tube should be centered in the vent holes of the handguard), pull the delta ring rearward again and "snap in" the rear of the top piece. Once it is firmly seated, the delta ring should clear the rear of the top piece and hold it in when it is released. It is necessary to make sure the front of the top piece is correctly centered (especially with the basic, two-piece handguards) in the two detents on the end cap to avoid difficulty when installing the front of the bottom piece of the handguard next.
