Featured in:

AR-15 jigs are an essential tool for gunsmiths and firearm enthusiasts. These jigs are used to assist in the assembly of AR-15 rifles, allowing for precise drilling and milling of lower receivers. The AR-15 is a popular rifle platform due to its versatility, reliability, and ease of customization.

Jigs come in various shapes and sizes, but they all serve the same purpose: helping you create a perfect lower receiver that will fit well with other parts of your rifle. Some jigs require manual operation while others can be automated with the help of CNC machines. No matter what type you choose, using an AR-15 jig ensures accuracy and consistency during manufacturing.

If you're looking to build your own custom AR-15 or want to perform maintenance on your existing rifle, investing in an AR-15 jig is a wise decision. In this article, we'll take a closer look at different types of jigs available in the market today along with their pros and cons so that you can make an informed purchase decision based on your needs.

AR 15 Jigs: The Ultimate Guide for Weapon Enthusiasts

As a weapon enthusiast, you know that there are few things more satisfying than building your own firearm from scratch. Not only is it an excellent way to hone your skills and knowledge, but it can also result in a truly unique and personalised weapon.

One of the essential tools for building an AR 15 is the jig. In this article, we will be exploring everything you need to know about AR 15 jigs – from what they are to how to use them effectively.

What Are AR-15 Jigs?

AR-15 jigs are specially designed tools that help guide users through the process of milling out different parts of an AR-15 lower receiver. Typically made from high-quality materials like aircraft-grade aluminium or steel, these jigs feature pre-drilled holes and alignment guides that help ensure accuracy throughout the milling process.

Benefits Of Using An AR-15 Jig

The main benefit of using an ar 5 jig when assembling your firearm is improved accuracy. Investing in a good quality jig kit will allow you to machine lowers precisely every time without compromising on quality or consistency.

Another significant advantage associated with using ar 5 jigs is their versatility. These tools can be used by both experienced gunsmiths as well as beginners who want to learn more about how weapons work while creating their custom firearms at home.

Types Of Ar-5 Lower Receiver Jig Kits

There are several types of ar -5 lower receiver kits available on the market today:

Billet vs forged receivers

Billet receivers start out as solid blocks before being machined into specific shapes,while forged ones begin life as castings before being cut down into shape.

Router-based vs drill press based

Router-based kits tend to be faster and easier than drill press options but do require some skill level with routers in order not ruin other parts of the receiver in the process. In contrast, drill press-based jigs are a bit more challenging to set up and use but offer greater accuracy for those who have experience with them.

Top vs side plates

Top plates are installed on top of an AR-15 lower receiver to guide users through the milling process, while side plates allow for more advanced operations like drilling bolt catch holes and trigger pinholes.

Tips For Using An Ar-5 Lower Receiver Jig

Using an ar 5 jig can be intimidating at first, especially if you've never attempted it before. Here are some tips that can help you get started:

  1. Study your instructions carefully: The instruction manual that comes with your jig kit will be your best friend when it comes to getting started. Read through all steps thoroughly before beginning milling operations.

  2. Take Your Time: It's easy to rush through a project when you're excited about its outcome – but doing so could result in costly mistakes or even dangerous accidents.

3.Check your work continuously:Double-checking measurements is vital not just once or twice but throughout each step of machining out th eparts.

4.Practice Good Safety Habits: Always wear safety glasses during the machining proces sas well as gloves protectors and other safety equipment as needed depending upon how far along in assembly one is.


Building an AR-15 using a quality jig kit is both satisfying and rewarding—that being said- working on firearms requires patience, skill,and accuracy beyond reproach . Whether you're new at building AR platforms from scratch or looking for ways tto improve upon previous builds -a good quality ar 5 lower receiver jig kit will take care of things by providing accurate guiding points every step along the way。 With this ultimate guide in mind , firearm enthusiasts (both novice & expert) should now feel confident enough knowing what they need before starting their next build project!


What is an AR 15 Jig and how does it work?

An AR 15 jig is a device that assists in drilling holes into an 80% lower receiver to complete the construction of an AR-15 rifle. The term "80%" refers to lowers that are not considered firearms by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) because they are only partially completed. This means that no serial number or background check is required for purchase.

The jig works by guiding the drill bit through specific areas of the lower receiver where holes need to be drilled in order to install various parts such as springs, triggers, and pins. It often comes with templates or guides which help ensure accuracy during drilling while also preventing damage to other parts of the lower receiver.

When using a jig, it's important to follow all instructions carefully and take precautions such as wearing protective gear like goggles or gloves when operating machinery.

What materials should I look for when buying an AR 15 Jig?

When looking for an AR 15 jig there are several materials you should consider:

  1. Aluminum: Many jigs on the market today feature aluminum construction due its lightweight nature making it easy for transportation.
  2. Steel: Another popular material used in manufacturing jigs due its durability against wear and tear.
    3.High-Density Polyethylene (HDPE): HDPE plastic has become increasingly popular lately for its low cost & reasonable durability

However what matters most isnt necessarily what material makes up your chosen Jig but rather if it will stand up well enough over time while you complete multiple projects with your given toolset!

Do I need any special tools or skills before using my newly purchased Ar-15 Jig?

Before purchasing any kind of gunsmithing equipment including jigs make sure you have a basic understanding about power-tools safety protocols as well safe firearm handling practices so risks can be minimized especially since machining operations require precision and attention to detail.

When it comes to tools, a drill press or milling machine is typically required when using an AR 15 jig since the drilling process requires high accuracy. A handheld power drill may also be used but with caution. The help of someone experienced in gunsmithing or machining operations is highly recommended for the first few times that you use your newly purchased Jig especially if you dont have experience.

What are some benefits and drawbacks of purchasing an AR 15 Jig?


  1. Savings: By building your rifle from scratch using an ar-15 jig instead of buying a pre-made one, cost savings can be realized as no Federal Firearms License (FFL) transfer fees otherwise known as shipping costs will need to be incurred.
  2. Customization: Building your own rifle allows for endless customization possibilities so that it's tailored specifically towards individual preferences.
    3.Legal Compliance – Use only legally obtained parts thereby avoiding legal issues while building.

1.Tools & Skill level Required – Proper care must be taken when operating machinery during drilling activities which can require prior technical know-how
2.Right Choice – With many jigs on the market available finding one that fits both user needs & budget may prove challenging
3.Time Investment : Crafting rifles takes time and patience especially when starting out which could lead to parts taking longer than desired timeframe before completing build

Can I use my Ar-15 Jig for other firearms besides just my Ar-15?

Jigs are often designed specifically for certain types of firearms, therefore check compatibility between toolset/jig specifications beforehand . It might not always work with different kinds!
