AR Build Customization: How to Create Your Own AR-15
These are some main aspects of AR build customization.
Barrels
Barrels are a critical part of your AR build. With a custom barrel, you can decide what caliber ammo you prefer and the amount of twist.
The twist rate determines how fast the bullet spins as it leaves the barrel, which affects its stability and accuracy.
A common twist rate for AR-15 barrels is 1:9, which means the bullet makes one full rotation for every nine inches of barrel length.
However, you can also find barrels with different twist rates, such as 1:7 or 1:8, depending on the type and weight of the bullet you want to use.
Another factor to consider when choosing a barrel is the length.
The barrel's length affects the bullet's velocity and accuracy, as well as the overall weight and balance of the rifle.
The legal minimum length for a rifle barrel is 16 inches, but you can also find shorter barrels for pistol builds or SBRs (short-barreled rifles).
However, these require additional paperwork and fees from the ATF. The most common barrel lengths for AR-15s are 16, 18, and 20 inches.
Finally, you can also choose from different profiles and finishes for your barrel. The profile refers to the shape and thickness of the barrel along its length.
Some common profiles are M4, government, heavy, and pencil. The profile affects the weight and heat dissipation of the barrel.
The finish refers to the coating or treatment applied to the surface of the barrel to protect it from corrosion and wear. Some common finishes are chrome-lined, nitride, phosphate, and stainless steel.
Handguards
Choosing the best-fit handguards for you is crucial to improving the function of your custom AR-15.
Handguards are the parts that cover the barrel and provide a place for you to grip and attach accessories to your rifle. There are two main types of handguards: drop-in and free-float.
Drop-in handguards are easy to install and remove without any special tools.
They consist of two pieces that snap together around the barrel and are held in place by a delta ring and a front sight post.
Drop-in handguards are usually made of plastic or polymer and have a standard shape and size. They may have some attachment points for accessories, such as Picatinny rails or M-Lok slots.
Free-float handguards are more advanced and require some tools and skills to install. They attach directly to the upper receiver or a barrel nut and do not touch the barrel.
This allows the barrel to vibrate freely without interference from the handguard, improving accuracy.
Free-float handguards are usually made of metal, such as aluminum or steel, and come in various shapes, sizes, and colors.
They also have more options for attachment points for accessories, such as Picatinny rails, M-Lok slots, KeyMod slots, or QD sling mounts.
Stocks
To improve the fit of your AR-15, purchase an adjustable stock.
Stocks are the parts that connect to the lower receiver and provide a place for you to rest your shoulder and cheek when shooting. Stocks can be fixed or adjustable in length.
Fixed stocks are rigid and do not move at all. They are usually made of wood or polymer and have a classic look.
Fixed stocks may be more durable and stable than adjustable ones, but they limit your ability to customize your rifle to your body size and shooting position.
Adjustable stocks are flexible and can be extended or collapsed along a buffer tube. They are usually made of polymer or metal and have a modern look.
Adjustable stocks allow you to adjust your rifle to your body size and shooting position, which improves comfort and accuracy. However, they may also be less durable and stable than fixed stocks.
80% Lower Receivers
If you want to build your own AR-15 from scratch, you will need a lower receiver.
The lower receiver is the part that houses the trigger group, magazine well, safety selector, bolt catch, and other components. It is also considered a firearm by law and requires a serial number and registration.
However, there is a way to avoid the hassle of buying a lower receiver from a licensed dealer and submitting to a background check.
You can buy an 80% lower receiver, which is a partially finished lower receiver that requires some additional machining to be completed.
An 80% lower receiver is not legally considered a firearm and does not require a serial number or registration.
To finish an 80% lower receiver, you will need some tools and skills, such as a drill press, a jig, and some drill bits.
You will need to drill out the fire control group cavity, the hammer pinhole, the trigger pinhole, and the safety selector hole.
You must also mill out the rear shelf and the trigger slot. Once you finish your 80% lower receiver, you can assemble it with the rest of the parts and enjoy your custom AR-15.
Magazines
Magazines are the parts that hold and feed the ammunition into your AR-15. Magazines can vary in capacity, material, and design.
The standard capacity for an AR-15 magazine is 30 rounds, but you can also find magazines with different capacities, such as 10, 20, 40, or even 100 rounds.
However, some states have laws that limit the capacity of magazines you can own or use.
Magazines can also be made of different materials, such as steel, aluminum, or polymer. Steel magazines are durable and reliable but also heavy and prone to rust.
Aluminum magazines are lightweight and corrosion-resistant but also fragile and prone to denting. Polymer magazines are flexible, resilient, and susceptible to heat and UV damage.
Magazines can also have different designs, such as curved or straight, ribbed or smooth, windowed or solid. These features may affect the performance and aesthetics of your magazines.
For example, curved magazines may feed more reliably than straight magazines, ribbed magazines may provide more grip than smooth magazines and windowed magazines may allow you to see how many rounds are left in your magazine.
