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. 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? Well, it's akin to pulling the string on a lawnmower to get things started.


The Lower Receiver: the Heart of the Matter


Now, let's chat 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. You can start by popping in a new magazine in the magazine well. Buttstock? The gun is resting on the shoulder.


Handguards and Rail Systems on the Swiss Army Knife


Have you 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 rails, M-Lok rails, or KeyMod Rails? Yeah, those are just fancy terms for different mounting systems for lights, lasers, and grips.


Gas System: The Middleman


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. It's like getting two birds with one stone--moving the bullet and readying the gun 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.
