Let’s be clear: this isn’t rocket-science, but it may feel like a puzzle to a newbie. Once you become familiar with AR15 Parts it will be just like playing your favorite videogame.

The upper receiver: the Brain Box

Start with the upper receiver. Think of this as the brain box of your rifle. This is where the action happens–literally. It houses the barrel, bolt carrier group (BCG), and charging handle. The barrel is where the bullets leave. What is the BCG? It’s like the engine, cycling the rounds. And the charging handle? It’s similar to the way you start a lawnmower by pulling a string.

The Lower Receiver: The Heart of the Matter

Let’s talk about the lower receiver. It’s not as glamorous, but this is the heart of your AR15. It’s where the trigger, magazine well, and buttstock live. The trigger is the direct link to action. Pop in a fresh mag in the magazine well, and you’re good to go. Buttstock? This is where the gun rests on your shoulder, giving you stability.

Handguard and Rail Systems: The Swiss Army Knife

Ever heard of a handguard? It’s a Swiss Army Knife attached to the barrel. It offers a place to mount accessories and protects you from the heat of the barrel. Picatinny, M-Lok, or KeyMod rails? Yeah, those are just fancy terms for different mounting systems for lights, lasers, and grips.

The Middleman in the Gas System

Gas is also used in your rifle to fire the bullet. Gases are released when you fire the gun, and they also cycle the BCG. This is like killing two birds at once: the bullet moves and the gun is ready for the next shot.

We’re not talking about ultra-obsessive routines here, but it is important to keep your AR15 clean. It’s like driving a car that has mud on the windshield. Keep it lubed and free of gunk, and it’ll treat you well.
