The AR 15 is perhaps the most flexible firearm ever developed almost every single piece of it is interchangeable – including the barrels. This is a huge reason why it is commonly used by the armed forces and law enforcement and has proven its worth for many years of service. This rifle is definitely ideal because it can be quickly disassembled and cleaned for repairs and maintenance.
Due to the rifle’s modular design, one upper receiver can quickly and easily be substituted for another. Some upper receivers come with the barrel included; these are commonly called “complete upper receivers”. AR 15 barrels come in many shapes, sizes, designs, and materials – it’s important to know the differences before purchasing.
Here are the basic things to know before purchasing:
The most ideal length of AR 15 barrels is 16 inches; it has been classified as an all-purpose length. In general, the longer ones shoot bullets a lot faster, farther and way more accurate in comparison to the shorter ones. A light-weight rifle with a 16 inches barrel is an excellent combination. There are different selections for lengths, but the most desired lengths are 14.5”, 16” and 20”.
There are several different types of material that these are made from, here are the most common:
- Chrome-Moly-VAdium (CMV) - this is the very common type of barrel steel which are available in two forms, they 4140 – carbon spec. 043 and 4150 – carbon spec. 0.48. The barrel steel that US armed forces use is the 4150 CMV.
- Stainless Steel – this is heavier as opposed to the other kinds of AR 15 barrels but it improves accuracy.
- Cold Hammer Forged (CHF) – this barrel is a lot more durable than the others, though only a small number of manufacturers produce this kind of barrel because of the high expense in producing one.
Barrel Twist Rate
This refers to the distance a bullet travels in the barrel to complete a full revolution. The industry standard is 1:7”, this means bullets can complete a revolution in every 7 inches travel. 1:7’ is what the greater part of armed forces rifles now have. The other variants are 1:8” and 1:9”.
The most popular AR 15 barrel’s contours are Lightweight (pencil), M4 and Heavy Barrel. Lightweight is among the most popular which is attributable to its easy maneuverable rifle design but it definitely has a shorter life than the rest. Heavy Barrel on other hand is widely known to add more life and level of resistance to your barrel.
Finding a good selection of AR 15 barrels can be hard for some first time builders. Hopefully this has helped you with your selection and makes your build go that much faster!
