3. Install the barrel in the upper receiver

The barrel is the heart of your AR pistol, so it’s important to install it correctly.

1. Make sure the barrel is the correct length for your upper receiver. AR-15 barrels are available in a variety of lengths, from 10.5 inches to 24 inches. The length of the barrel will affect the velocity of the bullet, so it’s important to choose the right length for your intended use.
2. Clean the inside of the upper receiver. A dirty upper receiver can cause the barrel to bind, so it’s important to clean it thoroughly before installing the barrel.
3. Apply a thin coat of grease to the inside of the upper receiver. This will help to lubricate the barrel and prevent it from binding.
4. Insert the barrel into the upper receiver. The barrel should slide into the upper receiver with little resistance. If it is difficult to insert, you may need to apply more grease or tap the barrel lightly with a hammer.
5. Secure the barrel in place with the barrel nut. The barrel nut is a large, threaded nut that screws onto the barrel and secures it in place. Tighten the barrel nut until it is snug, but do not overtighten it.

4. Install the gas block and gas tube on the barrel

The gas block and gas tube are responsible for directing the gas from the fired cartridge into the action of the rifle, which cycles the action and loads a new round.

1. Install the gas block on the barrel. The gas block is a small, cylindrical device that is installed on the barrel near the front sight. It has a hole in the center that allows the gas to pass through.
2. Install the gas tube on the gas block. The gas tube is a small, hollow tube that connects the gas block to the bolt carrier group. It is held in place by a roll pin.
3. Adjust the gas block. The gas block can be adjusted to allow more or less gas to pass through. This is necessary to ensure that the rifle cycles properly.

Once the gas block and gas tube are installed, you can move on to assembling the rest of the rifle.
