Building AR 15

More than 16 million people in the United States owned an AR15 in 2018.

People use these guns for self-defense, hunting, competitions, and in the military.

If you intend to use this type of gun, it is good to know all its parts and how it functions, to ensure safety.

Continue reading to discover the details of an AR15 build to further your knowledge on them!

Set a Budget

Much like any other project, you will want to set a budget while working on your AR15 build.

There are many customizations that you can make to your gun. Many of these can be expensive and quickly run up your bills. Make sure that you set a budget that is reasonable and fits your financial situation.

When considering your budget, it is important to know that each part can be costly on its own. When you build an AR15, you will need to have money saved up for the parts and tools needed.

Don’t underestimate the costs of the tools that you will need. Make sure that you write down the list of items you have to get.

Think About Your Time

Not only does an AR15 build require money, but it will also require a good amount of your time to work on.

Depending on how detailed you want your gun to be and how fast you want it completed, you will have to create a timeline. You should make sure that building your gun doesn’t take too long, otherwise, you can lose interest and parts. You should also take enough time, however, so that it is accurate.

It is recommended that you create a timeline from concept to design. This will help keep you on track and aware of your progress.

You will want to give yourself plenty of time to learn throughout the building process as well. Unless you have built AR15s many times, you will likely need to carefully read the instructions.

Give yourself plenty of time to create your AR15, and don’t forget to consider ordering tools. Some people can assemble an entire AR15 in less than 2 hours!

Purchase and Gather the Upper Parts

Make sure that you do plenty of research before purchasing anything when making the upper part of your gun.

The upper portion can include the piston system or a direct impingement system. The direct impingement system is gas-operated. It is utilized to power the part of the gun that disposes of used casings and chambers a new one.

Try looking for a light-weight direct impingement system, it helps with accuracy. This is also the cheapest option to go with. Piston systems run cooler, however, and work well with calibers.

You will also have to gather your parts for the piston system so that your gun can circulate entirely.

Get the Lower Parts

The next step to take care of is getting all of your lower parts of the gun.

You should include the following items on your list; a lower receiver, trigger, lower parts kit, buffer, stock, magazines, and grips.

The lower receiver is the actual firearm, itself. Depending on what you are looking for, you can get customizable triggers and stocks. You should check your local laws before buying stocks, not all places have them legalized.

For anyone on a tight budget, you can get aluminum lower parts. This material is much more affordable than polymer. Many places sell pre-made lower parts to save you time and energy.

Many people swear by the JP Enterprise tactical brand when getting parts.

Prepare Your Work Station

There are a couple of things that you should take care of before working on your AR15 project.

You will need to put a front sight block, torque wrench, and upper vice block clamp with a gas tube alignment tool in your work station. These tools can help you get the job done more efficiently and error-free.

A ring tool, roll pin installation tool, and an adjustable receiver link are also recommended if you want to build an AR15 properly.

If you are on a budget, there are ways to assemble your gun with fewer tools. The cheaper option includes; a multi-tool, a small ball peen hammer, needle-nose pliers, and a small drive pin punch. You may also require a flathead screwdriver and a torque wrench.

This option should cost you around $200, which is much less than if you were to buy all the other tools.

Assemble the Lower Portion

You will first need to assemble the magazine catch assembly.

After installing the spring and button, you will need to flip the receiver over to thread in the magazine catch. Next, you will need to put together your trigger guard. Use a long role pin to press the pin of the trigger guard and it will allow the trigger to slide in.

Ensure that everything is lined up and the trigger is secured in its place. Use a rolling pin to hammer everything down and then put it in a clamp. Many people recommend putting cloth or plastic between the clamp and gun so that it doesn’t damage the paint.

Your bolt catch assembly comes next and will require small pieces. You will have to depress the bolt catch to line up your pieces and use a needle to keep it in place. You can use needle-nose pliers to do this part.

Put Together the Upper Half of the Gun

Putting together the upper part of the gun will take the most time to complete.

When putting together the upper part of your AR15 you will need the upper receiver, barrel, gas block and tube, and the bolt carrier group. The upper portion also includes the charging handle, forward assist, and handguard as well.

A 16″ barrel is the standard size to go with. It has the least recoil and many people report smoother cycling. You can have your barrel lined with chrome or stainless steel, depending on your preferences.

The stainless steel options are better for accuracy and are easy to clean.

Next, you will need to assemble the bolt carrier group (BCG). The BCG is where the bullet passes through, along with hot gases. When working on the BCG, use grade eight fasteners to hold down the gas keys. This will prevent the hex bolts from coming loose from built-up pressure.

Take Care of the Gas System Length

Depending on the length of your gas system, your level of action will be affected.

The length of the gas system helps make sure that there is enough force to power the shot. The bullet must remain in the barrel when the gas goes to the bolt carrier.

When the bullets are in constant movement, you need a long enough gas system length so that each bullet can leave the muzzle. If you notice leakage, your barrel is too long and too much gas is building up.

Unfortunately, if there is a gas leak in the barrel, your entire system will become damaged. Most people get a 12-16″ barrel as the standard. Ultimately, the choice is yours.

Choose Your Handguard

Depending on the purpose of your gun, you can get a customized handguard or even none at all.

There are many types of handguards on the market to choose from and you can even match them with the theme of your AR15. If you want to cut costs in this area, you can get a basic style handguard that has all of the necessary features.

If you plan to use your gun in combat or for self-defense, a well-made and durable handguard is needed. More than 2.5 million times each year, people use a gun to protect themselves.

Be even more safe with a handguard.

Test It out

Once you have completed the steps above and have attached all of the parts, you can test out your gun.

Before heading to a safe area to shoot, you should review that everything is accurate and moving the way that it should. When you get to the gun range or other safe location, you can shoot a couple of rounds to feel if everything is working properly.

As long as bullets are leaving the chamber without any issues and the gun is holding together, you can work on your accuracy!

Master the AR15 Build

Whether you learn the AR15 build for defending yourself, competitions, or military use, you must know what everything does.

Learning how to build the gun will teach you everything you need to know about using this weapon and how to best ensure safe use.

After doing your research and setting a budget you can begin preparing your work station. You will need to fill it with all of the tools and parts necessary to get the job done. Although building an AR15 can become expensive, there are many ways to cut costs and remain under budget.
