AR LOWERS

• AR Lower Receiver: The lower receiver is the part of an AR (ArmaLite Rifle) that houses the trigger mechanism, magazine well, and the buttstock. It is considered the firearm’s core component and is regulated as the legal firearm in the United States.

2. Types of AR Lowers

• Forged Lowers: Made from a single piece of aluminum, forged lowers are strong and commonly used in AR builds. They offer durability and reliability.
• Billet Lowers: Crafted from a solid block of aluminum, billet lowers provide a unique aesthetic and can be customized for specific features. They tend to be more expensive than forged lowers.

• Receiver Sets: Some manufacturers offer complete sets that include both lower and upper receivers, which can be useful for building custom ARs.
