What is AR 15 Barrel? 🤔
It is an essential component of the AR-15 rifle, an increasingly popular semi-automatic rifle for shooting sports, hunting, and home defence. The barrel is where the energy from each shot originates and plays a crucial role in accuracy and precision.
🚩 Lenght – it determines how accurate and powerful the rifle will be, as well as its manoeuvrability. In general, shorter barrels are more manoeuvrable than longer ones, but they have less accuracy and power due to their reduced velocity. Longer barrels have higher velocities and therefore more accuracy and power, although they can be unwieldy in tight spaces.
🚩 Gas system – the barrel gas system works by redirecting some of the gases from firing through a series of ports drilled in the barrel. Gas systems come in three main types: direct impingement (DI), short-stroke piston (SSP) and long-stroke piston (LSP).
- 🏁 Direct impingement systems are generally considered to be more lightweight than other designs since they don’t require additional parts like pistons or op rods. They are also easy to clean since all of their components are easily accessible from outside of the gun.
- 🏁 Short Stroke Piston Systems: SSP systems feature a shorter piston stroke which reduces excessive movement inside the gun; thus decreasing felt recoil while improving accuracy and reducing wear on internal components like trigger groups, bolt carriers, etc.
- 🏁 Long Stroke Piston Systems: LSP systems feature longer pistons strokes which result in increased velocity as well as increased accuracy due to lower levels of vibration inside the gun during operation.
🚩 Twist Rate – it describes the distance in which the rifling or grooves inside the barrel make one complete rotation. A higher twist rate means that bullets are spun faster and remain more stable during flight, resulting in greater accuracy and precision. The most common twist rates for AR-15 barrels are 1:7, 1:8 and 1:9, with each representing a different number of inches per full rotation.

Types of AR 15 Barrel Profile 😎
The Barrel Profile is an integral part of the rifle and can have a major impact on accuracy, reliability, and performance. There are three main types of barrel profiles that you will typically find: Heavy (HBAR), Government (Gov’t), and Pencil (Pen).
- 🎯 Heavy Barrels (HBAR), also known as “heavy profile” or “bull barrels”, are characterized by their thick walls and heavyweight. This makes them ideal for precision shooting since the extra weight dampens the effects of heat, causing less warping and reducing vibration. The additional mass also helps to keep the barrel from flexing, which increases accuracy. However, this added stability comes at the cost of increased weight, which may be undesirable in certain scenarios.
- 🎯 Government Barrels (Gov’t) are shorter in length compared to HBARs and they feature a thicker profile than Pencil Barrels. They usually come with a thicker gas block and often include fluting on either side to reduce weight while maintaining strength. This type of barrel provides an excellent strength-to-weight ratio along with good performance out of the box which makes it popular among many shooters who want both accuracy and reliability
- 🎯 Pencil Barrels (Pen) are lightweight barrels that feature thin walls compared to other barrel profiles. This results in reduced heat absorption during long strings of fire, making them well-suited for applications such as competition shooting where rapid follow-up shots are required. However, due to their lighter weight, they may not be as accurate as other types of barrels when firing heavier rounds at longer distances.

How to Change a Barrel on An AR-15 ⚡
🟡 To begin, make sure the rifle is unloaded, with no magazine inserted and all ammunition removed from the area. Inspect the chamber of your barrel to make sure it’s completely empty before beginning any work.
🟡 Next, separate your upper receiver from its lower receiver. Remove the takedown pins and pull them back until they snap out of each side of their respective pins. Once those pins are disengaged, separate the upper and lower receivers by pulling them apart gently with both hands at the same time. You should now have access to your old barrel assembly.
🟡 Locate and remove the two screws which hold your handguard in place using a proper flathead screwdriver or Allen key. Lift up on one end of your handguard while pushing down on the other end to ensure it comes off without issue. After that, remove any gas tube components you may have installed (such as an adjustable gas block) by unscrewing them from their mounting points on either side of your barrel assembly.
🟡 With everything out of the way, you can begin installing your new barrel assembly place by sliding it into position within your upper receiver’s rail system. Before attaching it securely, align its centerline along with that of your bolt carrier group (BCG). Once aligned, use two properly sized hex nuts to secure it in place against your upper receiver’s rail system using a wrench or Allen key depending on what type of fasteners you have installed.
🟡 Once ready, attach any additional components (such as a gas block) onto either side of your new barrel assembly before reattaching your handguard in its original configuration – being sure to tighten every fastener for security’s sake! Finally, insert takedown pins back into their respective slots before joining up both upper and lower receivers together once more for good measure!
