AR 15 BARRELS FOR SALE

AR 15 BARRELS FOR SALE.

Wondering how to choose the right AR-15 barrel? That’s a question that many current and prospective owners of this popular rifle have been asking themselves since the first models hit the market back in 1959.

Whether you’re  purchasing a brand-new AR-15 or building your own, your choice of barrel will have a major impact on the rifle’s accuracy, performance, and longevity.

The good news is that there are plenty of options available that enable you to  customize your AR-15 barrel.

Careful evaluation of the following factors can be extremely beneficial when determining how to choose an AR-15 barrel that meets your unique requirements.

Length

The barrel length has a direct impact on muzzle velocity and accuracy. AR-15 barrels are available in lengths ranging from 7” to 24”, with 16” being the most common.

In addition to meeting the distance requirements of most shooters, rifle barrel lengths of 16” or greater do not require a Class III tax stamp from the Bureau of Alcohol, Tobacco, Firearms and Explosives.

The way you intend to use your weapon will help you determine the most appropriate length. If you will be shooting at longer distances, a longer barrel offers increased accuracy and sufficient pressure to enable peak ammo acceleration.

A shorter, lighter barrel is a better choice for maneuvering in confined areas or protecting your home. Also, keep in mind that adding one inch of length to a shorter barrel can result in a foot-per-second velocity increase of up to 200 feet.

The rate of increase will begin to slow at a barrel length of 11” and pretty much disappear when reaching 20”.

Most AR-15 owners can get by with a standard mil-spec barrel. However, heavy users will experience greater long-term benefits from a cold-hammer-forged barrel, which entails a process that uses a large hydraulic machine to hammer the barrel blanks from multiple sides.

This produces a slightly tougher, more durable barrel with a longer lifespan than its mil-spec counterpart. On the downside, you could pay as much as $75 or more for a cold-hammer-forged barrel.

Profile

The profile refers to the weight of the barrel. Profiles are broken down into three basic categories: lightweight, government, and heavy.

The heavier the barrel, the greater the resistance it provides to the buildup of heat when firing the weapon. A heavier barrel will last longer than a lighter one, making it a better choice for frequent AR-15 users. On the other hand, a lighter barrel makes the gun easier to carry.

The M4 government version is the most popular profile option, as it offers an acceptable compromise for many AR-15 owners between heavier and lighter barrels.

Mil-spec AR-15 barrels typically include a lining made of chrome poly steel for reasons that pertain mainly to longevity and cleanliness.

The chrome lining is beneficial for military use in high-humidity and saltwater environments because it offers excellent resistance to corrosion.

The chrome will also protect the barrel against heat and friction, helping to extend its lifespan. And because a chrome barrel is easier to clean than a stainless-steel barrel, it can further reduce the impact of corrosion and erosion over time.

Perhaps the biggest disadvantage to using chrome-lined barrels is that they can reduce the AR-15’s accuracy at long distances.

This is due to the unevenness of the chrome that results in high points within the barrel. However, the loss of accuracy typically does not occur at distances under 300 yards, which means the vast majority of recreational shooters will not be impacted.

A stainless-steel barrel, also known as a “match barrel,” normally does not contain a chrome lining, providing increased accuracy at longer ranges.

The downside is that stainless-steel barrels are more susceptible to damage due to corrosion and wear, although these factors are unlikely to pose an issue when using the weapon under “normal” operating conditions and occasional to moderate use.

Twist Rate

Twist rate refers to the number of rotations a bullet makes in relation to the number of inches it travels within the barrel after the weapon is fired.

For example, a 1:7 twist rate means that the bullet must travel 7” to make one complete rotation. A barrel with a 1:7 twist ratio enables a bullet to spin faster than one with a 1:9 or 1:12 ratio. A faster rotation results in greater bullet stability as it travels through the air.

A 1:9 twist ratio is the most common, although the weight of the bullet is also a consideration when determining the appropriate ratio. Recommended twist ratio-ammo weight-grain combinations are:

• 1:12-1:14 = 35 to 50 grain
• 1:9-1:10 = 45 to 70 grain
• 1:7-1:8 = 69 to 90 grain

How to Choose the Right AR-15 Barrel: Summing It All Up

In essence, your choice of an AR-15 barrel pretty much comes down to your reasons for owning and using an AR-15 in the first place.

If you purchase an AR-15 as a means of protecting your family and property from intruders or for occasional weekend target shooting or hunting, a standard-issue mil-spec barrel with a chrome lining is really all you need.

On the other hand, if you’re a competitive shooter or someone who needs maximum accuracy at long distances, a stainless-steel, cold-hammer-forged barrel with no chrome lining is your best option.
