How To Build an AR-15: A Comprehensive Guide

If you are a gun enthusiast, you might want to consider building your own AR-15 instead of buying one off the shelf. Building your own firearm can be both exciting and fulfilling, not to mention that it can also save you some money. In this article, we will provide step-by-step instructions on how to build an AR-15.

What is an AR-15?

Before we dive into the process of building an AR-15 from scratch, let's first discuss what exactly is an AR-15. Contrary to popular belief, the "AR" in "AR-15" does not stand for "assault rifle," but rather stands for Armalite Rifle after the company that developed it in 1956. The design was later sold to Colt and has since become one of the most popular rifles in America.

An AR-style rifle typically features a modular design which allows users to customize different components according to their preferences. It has become a go-to choice among gun enthusiasts due its accuracy and reliability.

Required Tools

Building your own firearm requires specific tools and parts which will vary depending on what parts kit or lower receiver you decide on purchasing; however here’s a comprehensive list of common tools:

  1. Vise Block
  2. Armorers Wrench
  3. Torque Wrench
    4.Ball-Peen Hammer
    5.Tweezers /Pliers Set
    6.Punch Set (Steel preferred)
    7.Screwdriver Set
    8.Roll Pin Punches/Starting Punches

Parts Needed

The primary distinction between buying guns pre-made versus constructing them yourself is getting all of their necessary components separately or as part kits then assembling them together based on personal preference.
Here’s a list of each component needed:

1.Lower Receiver Kit – This includes every part required for completing your stripped lower receiver.
2.Upper Receiver Kit – This includes every part required for completing your stripped upper receiver.
4.Bolt Carrier Group
5.Gas System
6.Trigger Assembly
7.Pistol Grip and Trigger Guard Assembly

Building Your AR-15: Step by Step Guide

  1. Build the Lower Receiver:

    • Install the trigger guard assembly onto the lower receiver.
    • Attach buffer tube to a stock or brace of choice before attaching to the lower receiver.
    • Add safety selector, grip and magazine release button.
  2. Build Upper Receiver:
    -attach handguard and barrel nut onto upper receiver using a torque wrench.
    -Install gas system components into appropriate location on barrel then place it inside handguard, tightening gas block screws following with sliding gas tube in place.

3.Install Bolt Carrier Group:

The BCG will slide through the rear of your upper for installation into rifle’s chamber as long as you pull back on charging handle so bolt is locked open.

4.Test Fire Your AR-15:

Take your newly built firearm to an accredited shooting range or gunsmiths who can check that its safety mechanism works correctly before trying out this new gadget yourself!


In conclusion, building an AR-15 from scratch may seem daunting at first but it's definitely worth it. It allows you to customize your firearm according to personal preferences while also saving some money in comparison with buying pre-assembled firearms off-the-shelf models available from different manufacturers . With careful preparation and attention-to-detail during assembly process , creating own custom-design weapon is easy enough even novice shooters or home tinkerers can do so if they have right tools along with patience!


What is an AR-15 and why should I build one?

An AR-15 is a semi-automatic rifle that has been incredibly popular among gun enthusiasts, hunters, and sports shooters for decades. It is highly customizable, modular, accurate and reliable rifle. Building your own AR-15 allows you to save money while also customizing it to fit your specific needs.

When building an AR-15 you have complete control over the components that are used such as the barrel length, trigger mechanism etc. These parts can be selected based on your preference which will impact how the final product performs – long-range shooting versus close-range shooting or varmint hunting versus big game hunting.

The biggest advantage of building an AR-15 yourself rather than buying one pre-assembled from a manufacturer is cost savings as well as customization capabilities.

Do I need any special tools or knowledge to build my own AR-15?

Building an AR 15 requires some basic mechanical aptitude but does not require extensive experience in gunsmithing or metalworking techniques. There are many online resources available today including detailed guides with step by step instructions on how to assemble various parts of the rifle so even those who are complete novices can do it themselves too.

You will need specialized tools like punches and armorer’s wrenches which can be found at most gun shops or online retailers specializing in firearms assembly kits for ar 1s5s. Detailed instructional videos exist all over YouTube aimed specifically at helping people accomplish this goal without spending much money either!

Always make sure when purchasing components that they match up with other compatible items; otherwise proper alignment may not occur causing unreliable function within operation cycle due faulty seating tolerances between different pieces involved here.

Is it legal for me to build my own rifle?

Yes! It’s perfectly legal in most states (although we suggest checking local legislation first) if you are legally able buy a firearm then there should be no issues with you building one. There are some exceptions like California, New York, and a few other states that have specific laws regulating the manufacturing of firearms at home.

It is important to note that you must follow all state and federal laws when it comes to owning or operating any firearm in the United States. This includes complying with local ordinances regarding storage, transport and use of your rifle too.

What are some things I should keep in mind while building my AR-15?

The first thing to keep in mind is safety – read up on proper handling techniques before embarking upon this project. Secondarily make sure that all components being used match up together well; otherwise reliability may be impacted which could result in more significant problems down the road.

Thirdly ensure components meet minimum quality standards when making purchase decisions as there are many manufacturers out there offering inexpensive parts but they may not perform properly within an operational cycle for instance – bad gas tubes can cause cycling issues during firing so choose wisely here!

Finally it’s important not only consider cost savings but also balancing those savings against reliability concerns as well – don’t cut corners just because something seems cheaper upfront if long term performance could be compromised due lack maintenance or usage history documenting.

Can I customize my AR-15 once it's built?

Absolutely! A huge advantage of building your own AR-15 is customization possibilities available making alterations after assembly relatively simple over time compared buying factory-built ones from manufacturers where customization isn't nearly as varied nor flexible.

There’s a vast market for customizing ar 1s5s rifles including everything from stocks (fixed vs adjustable), sights/optics (iron sights vs red dots/holographic), triggers (single stage vs two-stage) even handguards and grips!

When choosing aftermarket parts just make sure they’re compatible with your pre-existing system without causing alignment issues; again online reviews by fellow enthusiasts offer great insight into potential complications involved here which can save lots of headaches down the line!
