About Assault Rifles
Assault rifles like AR-15s are powerful weapons with a great deal of stopping power and large magazine capacity. This makes them an attractive option for self-defense, hunting, law enforcement, and other similar roles due to its capability to firing multiple rounds in rapid succession. But, what really defines an assault rifle?
What is an Assault Rifle?
An assault rifle is a type of firearm designed for military use, specifically for combat situations. They come in both military and civilian versions. Military assault rifles are characterized by a selective fire option which allows the user to switch between semi-automatic and burst or fully automatic fire modes. Their civilian counterparts usually only come in semi-automatic variants unless the owner possesses a "Class 3" (Class III/NFA) license to have select fire capabilities.
The defining feature of an assault rifle is its intermediate rifle cartridge, which is more powerful than a pistol cartridge but less powerful than a standard rifle cartridge. An assault rifle also usually has a detachable magazine, allowing for the rapid reloading of ammunition along with a shorter 16" barrel and a folding or telescoping stock which allows for easier shouldering, transport, and concealment. These distinguishing characteristics make the assault rifle a versatile weapon and a powerful tool for modern warfare.

Once you have found the perfect complete AR-15 upper for your needs, you will be ready to assemble and enjoy shooting your rifle.
What is a complete AR-15 lower?
The AR-15 complete lower is the lower section of an AR-15 rifle that houses the trigger and other components that are used to fire a round along with the stock and grip. Complete lowers can be made from several types of materials including aluminum and polymer. Lowers are serialized and considered "firearms". Therefore, they are regulated by the ATF and must be shipped to a federal firearms license (FFL) holder.
The lower itself houses of several parts including the trigger guard, magazine release, fire selector, buffer tube, pistol grip, safety selector, hammer, disconnector, and bolt catch. The lower is connected to the upper receiver with receiver pins. When a complete lower is assembled, the factory gun technicians install the parts including the stock, the buffer tube, and internal parts. They attach the trigger guard with screws, insert the magazine release, install the fire selector and safety selector, install the other internal parts, and secure the pistol grip. A complete lower will be properly assembled and inspected at the factory to ensure that it functions correctly and safely.
Again, a complete AR-15 lower comes with all of the components pre-installed so that no assembly is required (apart from attaching it to the upper). Complete lowers can be a good option for people who do not want to build one themselves. It is also important to briefly check all components of a complete lower to make sure they are in good working order before using it. With a complete AR-15 lower, you can easily build your own custom rifle without needing any additional parts or tools.
Building The AR-15: Getting Into The Parts
The Upper Receiver
The AR-15 upper receiver is the part of the rifle that attaches to the lower receiver. contains the barrel, bolt carrier group, and ejection port cover. Understanding what rifle parts are in the upper receiver is important for anyone who owns an AR-15. There are several components that make up the upper receiver, including the stripped upper receiver, bolt carrier group (BCG), charging handle, forward assist, dust cover (ejection port cover), barrel, gas block and tube, as well as a handguard or rail system. All of these parts play a critical role in the operation of the rifle.
For example, the forward assist is a button that helps close the bolt when it is not fully closed. The dust cover protects the interior of the upper receiver from dirt and debris. The charging handle is used to load a round into the chamber and also to clear any malfunctions that may occur. The barrel is where the bullet leaves the firearm and is typically made of stainless steel or chrome-molybdenum steel. The gas block and tube are responsible for directing gas from the barrel to the bolt carrier group to cycle the action. Lastly, the handguard or rail system provides a mount for accessories such as sights, lasers, and flashlights. Knowing what rifle parts are in an AR-15 upper receiver is essential for ensuring proper maintenance and safe operation of your rifle. Let's into each of the roles of these parts.
Stripped AR-15 Upper Receiver
An AR-15 upper receiver is an essential element of the AR-15 rifle, and a stripped upper receiver is even more essential. This component serves as the housing for the bolt carrier group, barrel, charging handle, and other components of the AR-15. It is possible to buy a complete upper receiver along with all its components, but many DIY rifle builders opt to purchase a stripped upper receiver and build their own custom AR-15. A stripped upper receiver is simply an upper receiver without any additional components. It is the basic foundation of the firearm and provides the framework for everything else that goes into it.
As the name implies, it has been stripped of all the parts which would otherwise be attached. Stripped upper receivers are available in both mil-spec (with forward assist) and commercial configurations (without forward assist), meaning they can be used with different types of AR-15 parts. Installing a stripped upper receiver is relatively straightforward and requires a few basic gunsmithing tools such as a barrel wrench and screwdriver. Once installed, it allows you to build an AR-15 from scratch or customize an existing one with aftermarket components. Ultimately, a stripped upper receiver is an essential building block for anyone who wants to build or customize their own AR-15 rifle.
AR-15 Bolt Carrier Group (BCG)
An AR-15 bolt carrier group BCG is a critical component of an AR-15 rifle. It usually comes as a unit (hence the name "group") or the five main BCG parts can be purchased separately. It consists of a bolt carrier, a gas key, a firing pin, a cam pin, and a bolt. The bolt carrier is the main component that holds the bolt in place and houses the firing pin. The gas key is attached to the top of the bolt carrier, and it serves as a conduit for high pressure gases to travel from the barrel to the bolt, allowing the firearm to cycle.
The firing pin is housed within the bolt carrier, and it’s responsible for striking the primer of the cartridge. The cam pin is located in the rear of the bolt carrier, and it assists with unlocking the bolt from the barrel extension. Lastly, the bolt is what actually locks into place when the action cycles, closing off the chamber with a tight seal. All these components work together to ensure reliable performance of your AR-15 rifle. Without them, you won’t be able to fire your rifle properly. It’s important to maintain your BCG and keep it clean for optimal performance.
AR-15 Charging Handle
An AR-15 charging handle is a key component of the AR-15 rifle. It is a metal component that is located on the upper receiver and is used to draw back the bolt to the rear and chamber a round. The charging handle is also what you use to clear a jam or misfire. It is important to make sure the charging handle and latch is properly lubricated and regularly cleaned as residue can build up and cause problems. When using the charging handle, always keep your face away from the muzzle and keep your finger off the trigger!
To cycle the charging handle, grab the handle firmly with your support hand, pull it all the way back, and lock it into place with the bolt catch (found on the lower receiver). This will draw back the bolt, allowing you to check the chamber for a round or insert a new one. Once you have chambered a round, release the handle using the bolt catch and let it slide freely forward until it locks into place. Understanding how to use an AR-15 charging handle is an essential skill for an AR-15 operator.
AR-15 Forward Assist
An AR-15 forward assist is a button that helps close the bolt when it is not fully closed. It is a part of the rifle that is designed to help the shooter in overcoming any issues with loading ammunition into the rifle's chamber. This part is typically found on the left side of the upper receiver and consists of an internal plunger and spring. Its primary purpose is to help the shooter chamber a round in the event of any loading issues.
To use the forward assist, the shooter must first press down on the forward assist button, which depresses the plunger, and then push it forward towards the bolt carrier. This action forces the bolt carrier group to move forward, chambering a round if there is one present in the magazine. The forward assist is not intended to be used as a replacement for proper cleaning and maintenance, but it can be used to help ensure reliability in cases of an unexpected jam or misfire.
AR-15 Dust Cover (Ejection Port Cover)
An AR-15 dust cover ejection port cover is an important component of the AR-15 firearm. This cover is designed to keep dirt, dust, and debris out of the upper receiver, BCG, and chamber of the firearm while not in use or not actively shooting. The cover usually attaches to the rear of the receiver and is usually held in place by a spring loaded clip. When the firearm is ready to be used, the user simply releases the cover off by cycling the charging handle, revealing the ejection port.
The dust cover helps to keep the firearm clean and free from dirt and debris, ensuring that it will function properly when needed. It also helps to keep moisture away from the firearm, preventing rust and corrosion that could lead to malfunction. The dust cover is an important component of any AR-15, and it is important that it is kept clean and in good condition.
AR-15 Barrel
The AR-15 barrel is the key component of the rifle, as it determines the accuracy and performance of the firearm. The length of the barrel affects the accuracy of the rifle, as does the twist rate. The twist rate determines how quickly the bullet spins, which helps increase accuracy. Other factors that affect accuracy include the type of rifling used, the size of the bore, and the type of ammo used. Additionally, certain features can be added to an AR-15 barrel to customize its performance, such as muzzle brakes or flash hiders. AR-15 barrels are available in different lengths, materials, and finishes to ensure they meet the needs of any shooter. Whether you are a competitive shooter or a hunter, an AR-15 barrel can help you hit your mark.
An AR-15 barrel is an important component of the AR-15 rifle. It is the part of the rifle that houses the ammunition (bullet, propellant, and primer) and fires the round down its length. The length of the barrel affects the accuracy of the rifle, as does the twist rate (internal rifling). The barrel length is generally between 16 and 20 inches in length, and it is typically made of chrome-moly steel or chrome lined steel. The AR-15 barrel also features rifling which spins the bullet as it travels down the barrel for increased accuracy. Standard twist rates include 1:7, 1:8, or 1:9 (see below for more info).
The barrel is attached to the upper receiver and is secured with two pins. The gas block sits at the front of the barrel and contains a gas tube that directs gas from the combustion chamber to the bolt carrier group. The muzzle device, which may be a flash suppressor, muzzle brake, or compensator, is attached to the end of the barrel.
What are AR-15 barrel twist rates?
Understanding AR-15 barrel twist rates can help you make better decisions when choosing a rifle or upgrading your current firearm. A barrel twist rate is the rate at which the rifling inside the barrel causes the projectile to rotate, and is expressed as a ratio of one length to one turn. Generally speaking, AR-15 barrels have a twist rate of 1:7, 1:8, or 1:9.
A 1:7 twist rate means that the bullet will rotate one full time in seven inches of barrel length. A 1:7 twist rate is great for shooting heavier bullets, while a 1:8 or 1:9 twist rate is better for lighter projectiles. For example, if you want to shoot 55 grain bullets, then you should look for a 1:9 twist rate. If you're looking to shoot heavier rounds like 77 grain bullets, then a 1:7 twist rate is what you need.
Some AR-15 rifle system and their barrels are also designed to fire multiple calibers. They usually have two different uppers (or quickly interchangeable barrels) with different twist rates, such as 1:8 and 1:7, and you can switch them out depending on which caliber you're shooting. The takeaway here is that understanding AR-15 barrel twist rates is key when it comes to selecting the best rifling for your specific needs. Knowing the appropriate twist rate for your round grain weight will ensure that your rifle's ballistic coefficient performs at its best and that you get the most out of your firearm.
AR-15 Gas Block
An AR-15 gas block is an essential component of the gas system of both a direct impingement AR-15 rifle or a rifle with a piston system. It is typically located near the front of the barrel assembly, and its primary purpose is to regulate the flow of propellant gases from the barrel to the bolt carrier group. The gas block is also responsible for directing the gases towards any additional components such as a suppressor or other muzzle device. A gas block is a critical component because it helps to ensure proper cycling and reliability of the firearm. It also helps to reduce recoil and keeps the rifle on target by directing the gases in the right direction.
There are several types of gas blocks, including adjustable, low profile, and clamp-on designs. Adjustable gas blocks are great for fine-tuning the gas system to match your ammunition, while low profile designs allow for more modularity in your AR-15 build. Lastly, clamp-on designs are easy to install and can be used with both direct impingement and piston driven guns. No matter what type of AR-15 you own, having a properly installed and regulated gas block is essential for reliable operation and accuracy.
AR-15 Gas Tube
The AR-15 gas tube is another important component of the overall AR-15 rifle system. It is a metal tube that runs from the gas block, which is located forward on the barrel, to the stripped upper receiver of the firearm. On a direct impingement AR-15, gas runs through this tube back to the BCG to cycle it. In a piston AR-15, this tube houses the gas piston assembly which is responsible for cycling the bolt carrier group after each round is fired. In order to ensure proper operation of the AR-15, it is important to understand the role of the gas tube and how it works.
The gas tube allows high pressure gas from the fired round to enter the upper receiver, which then sends a portion of the gas (aka signal) to the bolt carrier group and forces it to move back and eject the spent round. At the same time, the bolt carrier group also pushes a new round from the magazine into the chamber and locks it in place. This process, referred to as "direct impingement" is what allows for semi-automatic fire in an AR-15. If the gas tube becomes clogged or otherwise damaged, it can cause malfunctions in the firing cycle of the rifle. For this reason, it is important to inspect your AR-15 gas tube regularly and replace it as necessary if any signs of wear or damage are present.
AR-15 Handguard or RIS Rail System
An AR-15 handguard or rail system is an essential part of any AR-15 rifle. It provides an interface for mounting various accessories, such as a bipod, flashlights, laser sights, and even night vision optics. The handguard also helps protect your hands from the heat generated by the barrel and gas system during shooting. The rail system gives you a platform to securely attach accessories to your rifle. It consists of two parts, the upper and lower halves, which are typically made from aluminum or polymer.
The upper part of the rail system is attached directly to the barrel of the rifle. The lower part attaches to the upper part with screws and clamps, and then to the handguard. Depending on the type of rail system you choose, there may be slots in between the upper and lower parts that can be used to mount accessories. This allows you to customize your rifle to fit your exact needs. When choosing a handguard or rail system for your AR-15, it’s important to consider the type of accessories it can accommodate, as well as its overall weight and size.
The Lower Receiver
The AR-15 lower receiver is the second main part of the rifle and contains several integral parts. It houses the trigger group, magazine well, bolt catch, and firing mechanism. Within the receiver is the trigger assembly, which consists of the trigger, disconnector, hammer, and the necessary pins and springs to hold them in place. The magazine well is where a magazine is inserted into the lower receiver. The bolt catch keeps the bolt from opening when the rifle is not in use. Finally, the firing mechanism includes the safety selector switch and trigger guard for additional protection when handling the rifle. All these parts combined make up a complete lower receiver for an AR-15 rifle. With proper maintenance and care, these parts will ensure your AR-15 is always ready to go when needed.
Stripped AR-15 Lower Receiver
An AR-15 stripper lower receiver is an important component of the AR-15 rifle. It serves as the foundation for the rest of the rifle and holds all other parts together. It is made out of aluminum alloy like 6061-T6 or 7075-T6, and it is cast or forged to be a single piece of metal. High end AR lowers can also be CNCed from billet aluminum. When you first get your lower, it is stripped down without any components. This makes it easy to transport and to customize later in the build process.
Once built, the lower receiver holds various components such as the magazine catch, trigger guard, bolt release, safety selector, pivot pin, takedown pin, and trigger assembly. These parts are often bought together as a lower parts kit. These parts are also interchangeable so you can customize your rifle. The lower receiver also features a threaded hole at the rear of the receiver which allows for the installation of a buffer tube for a collapsible stock.
This makes the AR-15's length adjustable for different users and shooting styles. When constructing an AR-15 rifle, it is important to purchase a quality lower receiver from a reputable manufacturer. Using a high quality lower receiver will ensure that your rifle will last and be and reliable for years of shooting many thousands of rounds.

This makes it an ideal choice for those who need to switch between different shooting positions or who need to quickly adapt to different shooting scenarios. Selecting the right AR-15 buttstock will depend on your individual needs and preferences.
Buffer Tube
An AR-15 buffer tube is a critical component of an AR-15 rifle. It is an aluminum or polymer cylindrical tube which houses the recoil spring and buffer. The buffer tube is located at the rear of the gun, and functions to absorb the shock of the bolt carrier group cycling. In order to build an AR-15, it is necessary to install the buffer tube and ensure that it is properly secured with screws and castle nuts.
The tube itself can come in different sizes depending on the type of stock being used. Milspec tubes are used for fixed stocks, carbine tubes for collapsible stocks, and rifle tubes for A2 stocks. Additionally, there are also commercial spec tubes which are slightly larger than milspec tubes and are for use with commercial stocks. When shopping for a buffer tube, it is important to know the size and specifications of your stock in order to choose the correct tube. Proper installation of an AR-15 buffer tube is essential for the functionality and safety of your rifle.
Buffer and Spring
An AR-15 buffer and spring is another important component of the weapon's operation. The buffer is a metal tube that houses the recoil spring and a buffer weight. The buffer weight is a metal part that absorbs the shock of the bolt carrier group's rearward motion when fired. The buffer spring is a large coil spring that helps to return the bolt carrier group to its forward position after it has been fired.
This allows the gun to cycle and be ready to fire again. The buffer system also helps to reduce felt recoil, making the rifle easier to control. Proper maintenance of the buffer and spring is essential for optimal performance, and it should be checked periodically for signs of wear or damage. Replacing a worn or damaged buffer and spring can help ensure reliable operation of your AR-15.
Castle Nut
If you own an AR-15, chances are you've heard of the castle nut. The castle nut is a steel nut that serves an important purpose in the AR-15 and is an integral piece of the gun’s functionality. It is found at the back of the lower receiver and holds the receiver extension in place. This part is important because it secures the buttstock to the receiver extension, which houses all of the gun's internal components. The castle nut also helps to keep all those components together, preventing them from coming loose or shifting during firing.
It is held in place by two screws, with one side being slightly longer than the other to provide extra security. The nut also has two notches on either side to give it extra strength. Installing a castle nut correctly is essential for ensuring proper operation of your AR-15, so be sure to follow the manufacturer’s instructions when doing so.
