What is an AR-15 rifle?
The AR-15 is a semi-automatic rifle that is based on the design of the military’s M16 rifle.
What caliber does an AR-15 shoot?
The AR-15 typically shoots .223 Remington or 5.56 NATO ammunition, which are both intermediate cartridges.
Can an AR-15 be converted to full-auto?
No, it is illegal to convert a semi-automatic firearm to full-auto without proper licensing and authorization from the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF).
What is the difference between an AR-15 and an M16?
The M16 is a fully automatic variant of the AR-15. It is only available to military and law enforcement agencies and is legal for civilians to own with the proper paperwork or tax stamp.
What does the AR in Ar15 mean?
The “AR” in “AR-15” stands for “ArmaLite Rifle,” which is the name of the company that developed the weapon in the 1950s.
What is the purpose of a flash hider on an AR-15?
A flash hider is a device attached to the muzzle of a firearm that helps to reduce the visible flash when the gun is fired. This is done by dispersing the burning gases that exit the muzzle, which helps to conceal the shooter’s position and protect the shooter’s night vision.
Can an AR-15 be used for hunting?
Yes, the AR-15 can be used for hunting with the appropriate ammunition and in states where it is legal.
How accurate are AR15 rifles?
The accuracy of an AR-15 can vary depending on the quality of the rifle, the skill of the shooter, and the ammunition used. However, with proper maintenance and use, an AR-15 can be highly accurate.
What is the maximum effective range of a typical Ar15 long-gun?
The maximum effective range of an AR-15 can vary depending on the caliber and the specific rifle, but it typically ranges between 600-800 yards.
What is the difference between a direct impingement and a piston AR-15?
Direct impingement is the traditional operating system used in the AR-15, where the hot gases from the fired round are directed back into the receiver to cycle the action. A piston AR-15 uses a separate piston to cycle the action, which can make the rifle run cooler and cleaner.
Are there any legal restrictions on owning AR-15 modern sporting rifles?
The laws vary by state and country, but in general, owning an AR-15 is legal in the United States. However, certain states and municipalities have additional restrictions on the ownership and possession of AR-15 and other semi-automatic firearms. It is essential to check with local laws before purchasing or owning an AR-15.
Can I use .308 Winchester ammunition in my AR-15?
No, the AR-15 is chambered for .223 Remington or 5.56 NATO; using .308 Winchester ammunition can cause damage to the rifle and be potentially dangerous.
What is the difference between a carbine and a rifle-length AR-15?
A carbine-length AR-15 has a shorter barrel (typically 16 inches) and a shorter overall length compared to a rifle-length AR-15, which has a longer barrel (typically 20 inches) and a longer overall length.

What is the difference between a stripped lower and a complete lower?
A stripped lower is a lower receiver that does not include any internal parts, such as the trigger, hammer, and magazine release. A complete lower includes all the internal parts and is ready to be assembled with an upper receiver and other components.
What is a buffer tube, and what is its purpose?
A buffer tube is a cylindrical tube that attaches to the rear of the lower receiver and houses the buffer and spring that helps to cycle the action of the rifle.
How often should I clean my AR weapon?
The frequency of cleaning will depend on how often the rifle is used and the conditions it is used in. As a general rule, it is a good idea to clean the rifle after each use and at least once a month if it is not being used frequently.
What is the difference between a free float and a drop-in handguard?
A free-float handguard is not connected to the barrel and does not touch it, which means it does not affect the barrel’s harmonics. A drop-in handguard is a simpler and less expensive option, which is connected to the barrel and can affect the barrel’s harmonics.
What is the difference between a mil-spec and a commercial buffer tube?
A mil-spec buffer tube is built to the specifications set by the military, while a commercial buffer tube is built to a slightly different set of specifications, which are more relaxed. This means that a mil-spec buffer tube will have tighter tolerances and be more durable than a commercial buffer tube.
What is a trigger upgrade, and why would I want it?
A trigger upgrade is a replacement of the stock trigger in an AR-15 with an aftermarket trigger that can improve the trigger pull, reduce the trigger weight, and improve the overall accuracy.
What is a muzzle brake, and why would I want one?
A muzzle brake is a device that attaches to the muzzle of the rifle and helps to reduce recoil and muzzle rise by directing the gases from the fired round in a specific direction. This can make the rifle easier to control and improve accuracy.
What is a bolt carrier group, and why is it important?
The bolt carrier group is the part of the rifle that houses the bolt, carrier, and firing pin. It is responsible for moving the bolt in and out of battery, and it is an essential component of the rifle’s operation. A high-quality bolt carrier group can improve the reliability and durability of the rifle.
What is a handguard, and what are the different types available?
A handguard is the part of the rifle that surrounds the barrel and protects the shooter’s hand from the barrel’s heat. There are many different types available, including M-LOK, KeyMod, and Picatinny.
How do I properly sight in an AR-15?
Sighting in an AR-15 involves adjusting the iron sights or optics to align with the point of impact of the bullet at a specific distance. This process typically involves shooting a series of rounds at a target and making adjustments until the point of impact is where you want it to be.
What is the difference between a flat top and a carry handle upper receiver?
A flat-top upper receiver does not have a built-in rear sight, which allows for the use of a separate rear sight or optic. A carry handle upper receiver has a built-in rear sight and is typically less versatile.
How important is barrel length on an AR-15?
Barrel length can affect the velocity, accuracy, and handling of the rifle. Longer barrels tend to be more accurate but also heavier, while shorter barrels are more maneuverable but less accurate.

What is a suppressor, and how does it work on an AR-15?
A suppressor, also known as a silencer, is a device that attaches to the muzzle of a firearm to reduce the sound of the gunfire. It works by trapping and slowing down the expanding gases from the fired round, which reduces the noise. It is important to note that suppressors are heavily regulated, and possession of one requires proper licensing and a tax stamp.
