Build an AR-15: A Comprehensive Guide

Are you looking to build your very own AR-15? Whether you're a gun enthusiast or just interested in exploring the world of firearms, building an AR-15 can be a rewarding experience. Not only do you get to customize it according to your preferences, but it also allows for better familiarity and understanding of how this rifle works.

In this guide, we'll take you through the step-by-step process of building an AR-15 from scratch. From choosing the right parts and tools needed, to assembling each component together – we've got everything covered.

Understanding The Anatomy Of An AR-15

Before diving into the build process itself, let's first understand what makes up an AR-15 rifle. An average complete upper receiver assembly consists of:

  • Upper Receiver
  • Barrel Assembly
  • Gas System (Gas Block/Tube)
  • Bolt Carrier Group (BCG)
  • Charging Handle
  • Handguard/Rail system
    • Barrel Nut
    • Rail system
    • Muzzle device

Meanwhile, a lower receiver assembly includes:

  • Lower Receiver
    • Trigger group
    • Pistol grip
    • Stock
    • Buffer tube
      ○ Buffer spring
      ○ Buffer

Choosing The Right Parts

When it comes to building any firearm from scratch – choosing high-quality parts is crucial for both safety and performance purposes. Your selection would depend on various factors including your budget range as well as personal preferences such as weight or design style.

Some recommended brands for different components are:

Component Brand Recommendation
Upper Receiver Aero Precision
Barrel Ballistic Advantage
Bolt Carrier Group Bravo Company Manufacturing
Muzzle Device Strike Industries
Lower Receiver Aero Precision

Don't forget that some states may have specific laws regarding certain types of components, like barrel length or magazine capacity.

Tools Needed

Now that you have chosen your parts, it's time to gather all the tools needed for the assembly process. Here are some items you will need:

  • Vice block
  • AR-15 armorer’s wrench
  • Roll pin punches & starter punches
  • Torque Wrench
  • Upper Receiver vise block clamp
    • Lower receiver vise block clamp
    • Pin alignment tool

Assembling The AR-15

With all the required parts and tools in hand, let's get started on assembling your AR-15! While there may be slight variations depending on which specific parts and brand you choose, these general steps should help guide you through the process smoothly.

Step 1: Install The Trigger Group

Install trigger guard first using a roll pin punch and starter punch. Attach lower receiver to vice block clamp securely before installing various components of trigger group such as detent spring into pistol grip.

Step 2: Install Fire Control Group (FCG)

Place FCG into position within lower receiver with hammer properly placed over trigger pinhole at center of assembly.

Step3: Attach Bolt Catch Assembly

Insert bolt catch from left side onto pivot post before pushing roll pin in place with a roll pin punch set.

Step4: Insert Pivot/Takedown Pins And Buffer Tube Assembly

Once complete with above steps then insert pivot and takedown pins securely through holes located just above buffer tube location after attaching stock assembly onto buffer tube securing screw tightly fastened through end plate up against castle nut threads – torque this down if necessary according to instructions provided by manufacturer.

FAQs

What is an AR 15?

An AR 15 is a semi-automatic rifle that has become increasingly popular among gun enthusiasts due to its customizable nature and versatility. Its precision, reliability, and ease of use make it an excellent choice for hunters, competitive shooters, or anyone who enjoys shooting.

The name "AR" does not stand for "assault rifle," as some people mistakenly believe. It actually stands for ArmaLite Rifle – the original manufacturer of this type of gun.

Is it legal to build your own AR 15?

Yes! It's perfectly legal to build your own AR 15 from scratch. In fact, many firearm enthusiasts prefer building their rifles rather than buying one off the shelf because they can customize every aspect of the weapon according to their specific needs and preferences.

However, it’s important to keep in mind that there are certain laws governing firearms ownership and construction in different states. So before you begin building your own rifle ensure that you understand all relevant laws within your jurisdiction surrounding firearms ownership and construction so as not find yourself on the wrong side with law enforcement authorities.

For instance:

  • The lower receiver which houses all other components costs around $30-$150
  • The upper receiver costs around $100-$350
  • A standard barrel goes for about $80-$250 while premium ones run from $300 up
    A basic trigger may go for as low as$50 but high-performance triggers go up above ~$300

There are also various kits available online or through retailers that contain everything needed (minus tools) at varying price-points depending upon quality level desired by a buyer.

Do I need any special skills to build an AR 15?

Building your own rifle is a great way to learn more about firearms and how they work. However, it does require some technical knowledge and skill. You don't necessarily have to be a gunsmith or expert engineer, but you should have some experience with tools and be able to follow instructions closely.

Some essential skills required include:

  • Knowing how to properly use power tools
  • Ability read blueprints or understand diagrams outlining assembly process
  • Understanding the different parts that make up an AR 15

If you are inexperienced in assembling firearms but still want a custom rifle tailored specifically toward your shooting needs, consider attending classes offered by experts before attempting such builds on your own.

What are some tips for building my own AR 15?

Building an AR 15 can be time-consuming, so plan ahead and set aside enough time for yourself.
When constructing the weapon:

  1. Always double-check each step in the assembly process as one mistake could lead catastrophic consequences during operation of final product.
  2. Purchase quality parts from reputable manufacturers so you know that what you're getting meets industry standards.
  3. Ensure all components are compatible with one another before final purchase as not all brands/components work together seamlessly despite claiming universal compatibility
    4 Follow manufacturer’s guidelines closely when installing critical parts such as barrel nut torque parameters among other things
    5.Test fire once everything is assembled using recommended safety gear e.g hearing protection & eye protection

By taking these steps along with others outlined carefully documented guides online ensure successful completion of arming oneself with custom built firearm suited specifically toward individual needs while prioritizing safety measures throughout construction project
