Customizing Your AR-15: Everything You Need to Know About Complete Upper Build Kits

• Upper Receiver:

  The upper receiver is the main component of the upper assembly. It's the part that attaches to the lower receiver and holds all the other parts.

• Barrel:

  The barrel is the long, cylindrical metal tube that the bullet travels through when fired. It's one of the most important parts of the gun, as it determines the accuracy and velocity of the bullet.

• Bolt Carrier Group:

  The bolt carrier group is the heart of the gun. It's responsible for feeding, firing, and ejecting the rounds.

• Charging Handle:

  The charging handle is the mechanism used to manually load the first round into the gun.

• Gas Block and Gas Tube:

  The gas block regulates the flow of gas from the barrel to the gas tube, which in turn powers the bolt carrier group. The gas tube carries gas from the gas block to the bolt carrier group.

• Handguard:

  The handguard is part of the gun that covers the barrel and provides a place to hold onto the gun.

• Muzzle Device:

  The muzzle device is part of the gun that attaches to the end of the barrel and helps to control the recoil and muzzle rise.

• Forward Assist and Ejection Port Cover:

  The forward assist is a button on the upper receiver that manually pushes the bolt carrier group forward if it does not fully close. The ejection port cover is a small metal flap that covers the ejection port to prevent debris from entering the gun.
