Diagram of AR 15 Parts: Everything You Need to Know

The AR-15 is one of the most popular rifles in America. It's a semi-automatic rifle that can be used for hunting, self-defense, and recreational shooting. If you're interested in owning an AR-15, it's important to understand the different parts and how they work together.

In this article, we'll provide you with a comprehensive diagram of all the parts that make up an AR-15. We’ll also explain what each part does so you can better understand how your rifle works.

The Upper Receiver

Let's start with the upper receiver, which is where many of the most critical components are located:


This is where your ammunition travels as it leaves your gun’s chamber.

Gas Block

Responsible for controlling gas flow from barrel through gas tube

Charging Handle

Allows user to charge weapon after each shot cycle or malfunction

Lower Receiver

The lower receiver holds many key components such as:

Trigger Assembly

The trigger assembly houses all necessary mechanisms required for accurate firing control and management thereof.

Buffer Tube

Buffers recoil shock from upper receiver’s bolt carrier group slamming backward into lower reciever buffer spring which reduces felt recoil impulse perceived by shooter.

Bolt Carrier Group (BCG)

The BCG cycles rounds through your gun when fired and has three main parts:

  • Bolt: This locks onto ammunition before pulling back straight out after shots cycled.

  • Firing Pin: This strikes primers on rounds within chamber igniting powder charges propelling bullets forward

  • Cam Pin : Shepherds movement between bolt /bolt carrier


A handguard serves both protective function over exposed hot barrel surfaces during operation but also provides mount points along its length allowing attachment accessories such as flashlights,laser sights,optical scopes etc..

Now that we've covered each component of the AR-15, let's talk about their benefits and how they work together.

One of the main benefits of an AR-15 is its modularity. You can easily swap out parts to customize your rifle to your liking. If you want a longer or shorter barrel, for example, you can replace it without having to buy a whole new gun.

Another benefit is that the AR-15 is incredibly reliable. Its gas impingement system allows for minimal carbon buildup and maximum reliability even in harsh conditions such as rain,dusty environments etc..

However, with great power comes great responsibility. It's essential to practice proper safety measures when handling any firearm.

In conclusion, if you're considering purchasing an AR-15 rifle or are already an owner looking to understand it better than understanding all its components is crucial knowledge required by all users alike inorder make informed choices about upgrades,optical accessories,maintenance schedules etc..


What are the parts of an AR 15?

The AR 15 is a popular rifle among gun enthusiasts, hunters, and military personnel. The rifle is made up of several components that work together to make it function properly. Some key parts include the upper receiver, lower receiver, barrel assembly, bolt carrier group (BCG), trigger assembly and stock.

The upper receiver contains the barrel assembly which includes a gas tube that directs propellant gases from each shot into the BCG. The bolt carrier group consists of a bolt carrier and firing pin while also housing other smaller components essential for operation.

The lower receiver houses both major assemblies in addition to providing space for other internal mechanisms like springs or buffers. Finally, there are numerous parts in between like handguards that protect you from heat generated by firing your weapon.

How do I disassemble my AR 15?

Disassembling an AR-15 requires careful attention to detail and following precise instructions specific to your firearm model. Before any disassembly occurs; ensure proper safety measures have been taken including removing ammo magazine/clip from firearm chambered round cleared out before proceeding with steps outlined below:

Step-by-Step Disassembly Guide:

  1. Remove magazine
  2. Lock back Bolt Carrier Group (BCG)
    3) Push out rear take-down pin
    4) Pull out front pivot pin
  3. Carefully separate upper & lower receivers by pulling them apart vertically.
    6a) Push takedown detent spring aside if needed.
    6b.) Remove buffer retaining detent part located on buffer tube next part moves freely now until fully removed.
    7.) Slide off Buffer Tube Assembly with these two pieces attached: spring inside metal cylinder/buffer weight at end

With practice over time you will be able to refine this process moving faster without sacrificing accuracy or safety during use.

Where can I find a complete diagram of ar-15 parts?

Finding complete diagrams online is relatively easy. There are several resources available that provide detailed images of AR-15 parts and their functions. To begin, try searching for "AR 15 exploded view diagram" or "AR 15 parts diagram" in your preferred search engine.

One popular resource is Brownells which has a comprehensive arsenal of AR-15 components, how-to guides and videos with examples on disassembly/assembly topics too.

Another source is the firearm industry forums where gun enthusiasts often post helpful tips on finding schematics or diagrams online; they may also share feedback about trusted sources and areas to avoid when looking for part diagrams.

What are some common issues with AR 15s?

Like any mechanical device, the AR-15 can have its fair share of problems from time to time. Some common problems include failure to feed properly due either to magazines not working correctly or an issue related directly with chambering rounds into barrel assembly as they’re fired off resulting in jams that might be difficult clear out quickly enough during high-stress situations like self-defense scenarios.

Other potential issues include worn out springs within your buffer tube assembly causing malfunctions such as trigger malfunctions due either by light primer strikes caused by insufficient force delivered through firing pin channel leading up towards bolt carrier group (BCG)—or other more unusual mechanical failures that require careful examination from qualified professionals who specialize specifically within this area for repair/maintenance work.

Can I upgrade my ar-15's parts?

Yes! The beauty behind owning an AR 15 rifle is how customizable it can be based on individual preferences. There are countless aftermarket options available ranging from simple upgrades like swapping out grips all the way up towards custom stocks/barrels/etc.. Gun shops offer these services now too so don't hesitate reaching out if you need assistance!

Many people choose upgrading sights/optics for better accuracy at further distances while others focus more heavily upon ergonomics such as changing handguards/grips etc to make it easier to hold steady at longer ranges. Some choose more tactical upgrades such as flashlights or lasers which can be mounted onto rails built right into the rifle itself; the possibilities are endless.

However, if you're looking for new parts keep in mind that there are both budget-friendly options and higher-quality components available depending on your preference/requirements with pricing spanning a wide range from affordable all the way up towards premium selections offering greater durability/performance during use over time.
