Let’s be clear: this isn’t rocket-science, but it may feel like a puzzle to a newbie. Trust me, once you’re familiar with your AR15 Parts, it’ll be like understanding the quirks of your favorite video game.

The upper receiver: the Brain Box

Start with the upper receiver. Think of this as the brain box of your rifle. It’s literally where the action takes place. It houses the barrel, bolt carrier group (BCG), and charging handle. The barrel is the long tube where bullets exit. The BCG? The engine is like that. The charging handle is it? 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. This part doesn’t get as much glam, but it’s the real heart of your AR15. This is where the magazine well, trigger and buttstock are located. The trigger is your direct connect to the 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.

Handguards and Rail Systems on the Swiss Army Knife

Ever heard of a handguard? If not, think of it as a super versatile Swiss Army knife attached to your barrel. It protects your hands from the barrel’s heat and offers you a spot to mount accessories. Picatinny, M-Lok, or KeyMod rails? These are all terms used to describe different mounting systems that can be used for lasers, lights, grips, etc.

The Middleman in the Gas System

Your rifle also has a gas system, the middleman in the firing process. When you fire, gases push the bullet out of the barrel, but they’re also redirected to cycle the BCG. This is like killing two birds at once: the bullet moves and the gun is ready for the next shot.

Look, we’re not talking ultra-obsessive cleaning routines, but you do need to keep your AR15 in good shape. A dirty rifle is like trying to drive a car with mud all over the windshield–not ideal. It will treat you well if it is kept lubricated and free from gunk.
