How to Make an AR-15: A Comprehensive Guide

If you’re looking for a guide on how to make an AR-15, you’ve come to the right place. Before we get started, let’s clarify that building an AR-15 from scratch is not difficult. It just requires some basic mechanical skills, patience and attention to detail.

Getting Started

First things first – before we start assembling your rifle, it is important that you have all the necessary parts and tools at hand. Here are the items required:

Item Quantity
Lower Receiver 1
Upper Receiver 1
Barrel 1
Bolt Carrier Group (BCG) 1
Charging Handle 1
Muzzle Device -You can choose between a flash hider or muzzle brake –
Rifle-Length Gas Tube -Choose one with proper length suitable for your barrel configuration –
.750’ Gas Block -Type of gas block depends on rail system used in upper receiver assembly—choose low profile if utilizing free float rails –
or standard height otherwise

Tools Required:

  • Armorer’s wrench
  • Punch set
  • Torque Wrench
  • Vise
  • Vise Blocks

Once you have all of these items ready, make sure that your work area is well lit and clean.

Step-by-step guide

Step One: Install Lower Parts Kit.

Begin by installing lower receiver parts kit as per instructions in manual provided with package. This will include trigger assembly elements like safety selector lever,
hammer spring ,disconnector ,trigger control group etc.
The most important point during installation being safety selector lever which gives options of safe/semi-auto firing mode.

Step Two: Install Buffer Tube Assembly.

Slide buffer tube into rear end portion after attaching castle nut using armorer's wrench.Since this element comes in two varieties, mil-spec and commercial, it’s important to choose the appropriate one for your lower receiver.

Step Three: Install Buttstock.

Once buffer tube assembly is in place ,attach buttstock depending on personal preference. This will require installation of locking plate and castle nut with torqued strength using armorer's wrench.

Step Four: Install Upper Receiver

Assemble upper receiver components (like forward assist ,ejection port cover),charging handle as well as gas block onto barrel before attaching to upper receiver itself.Installation of a muzzle device aligns the barrel with the compensation mechanism.
For free float rail customization you need to buy separate set of tools like torque wrenches, vice blocks etc.

Step Five: Complete Assembly Via Bolt Carrier Group Installation

Slide in BCG into rear portion through charging handle after lubricating carrier group parts properly.Most importantly,push it enough so that bolt catch lever can hold it .


By following this step-by-step guide, you should be able to successfully build an AR-15 from scratch. While there may be slight variations based on individual preferences or modifications chosen for customizing certain elements like rail systems or optics configurations,the basic building process remains essentially same every time.

Building an AR-15 can be a fulfilling experience that allows you complete control over your firearm’s configuration at relatively low costs compared to buying pre-assembled rifles from manufacturers.However there are local laws regarding firearms manufacturing which needs proper attention so make sure about relevant state/county laws before proceeding ahead

So go ahead and start assembling your dream rifle today!


What is an AR 15, and why would I want to make one?

An AR-15 is a semi-automatic rifle that was originally designed for the military. It has since become incredibly popular in the civilian market due to its versatility and customizability. Making your own AR-15 allows you to tailor the rifle specifically to your needs, whether it be for hunting, target shooting or home defense. Additionally, building your own firearm can be a fun and rewarding experience.

Is it legal to build my own AR 15?

Yes. In the United States, it is perfectly legal for individuals who are not prohibited from owning firearms (i.e., felons) to build their own rifles at home without having a Federal Firearms License (FFL). However, you must follow all federal and state laws regarding firearms manufacturing.

One important requirement during assembly of an AR-15 receiver – regardless of whether or not its stripped – involves engraving with unique markings as prescribed by ATF rules.

How difficult is it really to build an AR 15?

Building an AR-15 requires some basic mechanical skills but does not require any specialized gunsmithing knowledge or tools beyond those commonly found in most households; such as punches & hammers.
The actual process of building can be broken down into several sub-tasks:

  1. assembling lower receivers,
  2. installing triggers,
  3. attaching barrels,
  4. mounting handguards/grips/sights/optics/stocks
    However just like anything else worth doing well; careful planning before starting should go a long way towards making things easier on yourself when you begin taking action.
    Fortunately there are numerous videos available online that provide step-by-step guidance on how-to-build-an-ar-15

Assembling parts may require following written manual instructions closely – frequently referring back-and-forth between steps – so accuracy & attention-to-detail will help prevent errors which could ruin completion progress OR even cause unsafe working conditions for the assembled firearm.

What parts do I need to build an AR 15?

The main components of an AR-15 include the upper and lower receivers, barrel, gas system (if applicable), handguard, bolt carrier group, charging handle and trigger assembly. However keep in mind that there are many variations of each component available on the market so careful research needs to be done before making selections.
For example types of barrels; length & twist-rates vary widely depending on what your intended use is with rifle. A heavy-barrel will produce more heat than a thin one; some lengths may restrict your maneuverability when hunting or target-shooting.

A few additional items will aid in building:

  1. a vise,
  2. punches,
  3. torque wrenches

You'll also want to be sure you have appropriate safety equipment such as protective glasses while assembling.

How much does it cost to build an AR 15?

The total cost of building an AR-15 will depend mainly on how many features you choose for it. The most basic builds can start at around $400-$500 but if you go all-out with premium parts then costs could end up being well above $1000.

Bargain hunting options should be considered especially if this is going yo be first time firearms project.
One can find deals via searching websites online which offer regular sales/clearance prices – just make sure they're reputable sources.
If you're not interested in fully built lowers or pre-installed triggers/pistols grips etc.. then purchasing stripped lowers/upper receivers separately from other retailers can lead towards lesser-expensive options overall.

Regardless of what choices are made during purchase process always verify that everything selected works together properly BEFORE attempting assembly work begins – making swaps after beginning assembly may require entire restarts!
