The exterior of the barrel features a nitride coating to resist corrosion and rust, therefore increasing the barrel’s service life. And the barrel is chambered in .223 Wylde and has a 1/8 twist rate that increases precision when using either 5.56 NATO or .223 Remington rounds.

Best AR-15 Barrels Buyers Guide
Before you choose the best AR-15 barrel, you need to consider some important factors, so let’s take a look at them…
Chrome or Stainless Steel
Stainless-steel and chrome are two of the most commonly used materials in the manufacturing of AR-15 barrels. Both have their advantages and disadvantages. Chrome is excellent for preventing corrosion, ensuring a longer, trouble-free barrel life. With the average lifespan of a chrome-lined barrel being usually between eight and ten years.
However, stainless steel barrels are ideal for longer range shots. So, it’s a matter of your intended use and your personal preference, to be honest.
The “profile” is the design or shape of the barrel, which has an impact on its weight, which, in turn, affects the overall weight of the gun. Among the most popular barrel profiles are Recce, M4, Gov’t, and Pencil.
Barrels with heavy profiles have enough thermal mass to resist and absorb immense heat during full-auto shooting. Pencil barrels, on the other hand, are lighter and better suited to semi-automatic or single shots.
A recce, also known as reconnaissance, tends to be on the heavier side and normally features a mid-length gas system. Whereas, the M4 is a mixture of heavyweight and lightweight barrels. It is lighter beneath the handguard and thickens toward the gas port.
Wylde vs. 5.56 Chambering
Barrels chambered in .223 Wylde can fire both the 5.56mm NATO and .223 Remington ammo safely, allowing you more round options.
Barrel Twist Rate/Rifling
The type of ammo you choose will determine the ideal ratio for your barrel. For shooters who do not take longer range shots, 1/7 or the 1/9 ratios are fine because they work well with 55 or 62 grain bullets.
The length of the barrel is equally important. For instance, a short barrel cannot be used to engage long-range targets because of reduced muzzle velocity. Instead, a shorter barrel is best for easy target acquisition and maneuverability in short-range and close combat scenarios. Whereas a longer barrel, of around 20-inches, is ideal for long-range targets.
