Lower Receiver

The lower receiver is the heart of the AR-15. It is the part that houses the trigger assembly, the magazine, and the bolt carrier group. It is also the part that is serialized, so it is the part that the ATF tracks.

There are two main types of AR-15 lower receivers:

• Mil-spec: These are made to military specifications and are compatible with all mil-spec parts.
• Commercial: These are not made to military specifications and may not be compatible with all mil-spec parts.

When choosing a lower receiver, it is important to decide what type of build you are going for. If you are building a clone of a military rifle, then you will need a mil-spec lower receiver. If you are building a custom rifle, then you may want to consider a commercial lower receiver.

Once you have chosen a lower receiver, you will need to assemble it. The assembly process is relatively simple, but there are a few things to keep in mind.

First, you will need to install the trigger assembly. The trigger assembly consists of the trigger, the hammer, the disconnector, and the safety selector. The trigger assembly is installed in the trigger housing, which is located in the lower receiver.

To install the trigger assembly, you will need to:

1. Insert the trigger housing into the lower receiver.
2. Install the trigger pin.
3. Install the hammer pin.
4. Install the disconnector pin.
5. Install the safety selector.

Once the trigger assembly is installed, you will need to install the magazine catch. The magazine catch is a small lever that holds the magazine in place. The magazine catch is installed in the magazine well, which is located in the lower receiver.

To install the magazine catch, you will need to:

1. Insert the magazine catch into the magazine well.
2. Install the magazine catch pin.

Once the magazine catch is installed, you will need to install the bolt catch. The bolt catch is a small lever that holds the bolt open when the magazine is empty. The bolt catch is installed in the bolt catch slot, which is located in the lower receiver.

To install the bolt catch, you will need to:

1. Insert the bolt catch into the bolt catch slot.
2. Install the bolt catch pin.

Once the bolt catch is installed, you will need to install the bolt carrier group. The bolt carrier group consists of the bolt, the bolt carrier, and the firing pin. The bolt carrier group is installed in the upper receiver.

To install the bolt carrier group, you will need to:

1. Insert the bolt carrier group into the upper receiver.
2. Install the forward assist.
3. Install the dust cover.

Once the bolt carrier group is installed, you will need to install the barrel. The barrel is a long, cylindrical tube that is attached to the upper receiver. The barrel is installed by threading it into the barrel extension, which is located in the upper receiver.

To install the barrel, you will need to:

1. Clean the threads on the barrel and the barrel extension.
2. Apply a small amount of thread sealant to the threads on the barrel.
3. Thread the barrel into the barrel extension.
4. Torque the barrel to the specified torque.

Once the barrel is installed, you will need to install the gas block. The gas block is a small, cylindrical device that redirects gas from the barrel to the bolt carrier group. The gas block is installed by threading it into the barrel.

To install the gas block, you will need to:

1. Clean the threads on the gas block and the barrel.
2. Apply a small amount of thread sealant to the threads on the gas block.
3. Thread the gas block into the barrel.
4. Torque the gas block to the specified torque.

Once the gas block is installed, you will need to install the gas tube. The gas tube is a small, flexible tube that connects the gas block to the bolt carrier group. The gas tube is installed by inserting it into the gas block and the bolt carrier group.

To install the gas tube, you will need to:

1. Insert the gas tube into the gas block.
2. Insert the gas tube into the bolt carrier group.

Once the gas tube is installed, you will need to install the handguard. The handguard is a long, cylindrical tube that covers the barrel and the gas system. The handguard is installed by sliding it over the barrel and the gas system.

To install the handguard, you will need to:

1. Slide the handguard over the barrel and the gas system.
2. Rotate the handguard until
