The material of an AR-15 barrel can significantly impact its performance, weight, and durability. Here are the most common materials used:

Material Description Pros Cons
Stainless Steel High-quality, corrosion-resistant steel Excellent durability, corrosion resistance Heavier than aluminum
Carbon Steel Strong, cost-effective steel Good durability, cost-effective Prone to corrosion
Aluminum Lightweight, durable metal Significant weight reduction, good durability Less corrosion-resistant than stainless steel
Titanium Extremely lightweight, strong metal Extremely lightweight, high strength-to-weight ratio Expensive, more complex manufacturing process

Barrel Threading

Barrel threading is an essential factor to consider, as it determines the compatibility of accessories like flash suppressors, muzzle brakes, and sound suppressors. Here’s a breakdown of the most common threading options:

  • 1/2×28 TPI: The most common threading, suitable for a wide range of accessories.
  • 5/8×24 TPI: Used for heavier accessories, such as large suppressors.
  • 9/16×24 TPI: Less common, but suitable for some specialized accessories.

Chambering

Chambering refers to the internal shape of the barrel, which determines the type of ammunition it can fire. Here are the most common chamberings for AR-15 barrels:

  • 5.56x45mm: The most common chambering, suitable for a wide range of ammunition and accessories.
  • .223 Remington: Similar to 5.56x45mm, but with slightly different dimensions and performance characteristics.
  • 6.8 SPC: A more powerful round, offering increased range and penetration.

Barrel Lengths

Barrel length is another critical factor to consider, as it affects the rifle’s weight, balance, and performance. Here are the most common barrel lengths:

  • 10.5 inches: A versatile length, suitable for various shooting scenarios.
  • 11.5 inches: Offers improved accuracy and velocity, but at the cost of increased weight and length.
  • 16 inches: A classic length, providing a good balance between weight, balance, and performance.
  • 20 inches: The longest barrel length, offering the best accuracy and velocity but at the expense of increased weight and bulk.

Barrel Profile

The barrel profile refers to the shape of the barrel, which can impact its weight, balance, and cooling. Here are the most common barrel profiles:

  • Carbine: A lightweight, compact barrel profile, suitable for close-range combat.
  • Mid-Length: A balanced profile, offering a good compromise between weight, balance, and cooling.
  • Full-Length: The heaviest and longest barrel profile, providing the best cooling and accuracy.
