Davidson Defense "Irithyll" AR-15 Pistol Barrel 7.5" Contour
1-7 Twist 5.56 NATO Phosphate Finish
General Barrel Info: The Barrel on an AR-15 pistol operates through a 'gas impingement' system, where gas is tapped from off from the barrel and cycle back through a connected gas system, to help the bolt carrier in unlocking, and extracting a spent cartridge. Pistol length AR-15 barrels come in two gas lengths, Pistol & Carbine. AR-15 Pistol barrels can be chambered in a variety of different calibers, spanning from rifle to pistol cartridges. Thanks to the modularity of the AR-15 platform, your next pistol will be incredibly easy.

About the Profile: Medium - Medium Profile barrels are designed to have an even weight distributed from the beginning to the end of the barrel, this results in a rather tubular looking appearance but with identical rigidity and properties to a government profile barrel.

Length: This Barrel is designated as a pistol length barrel with an overall length of 7.5".
Caliber: 5.56NATO - This barrel is chambered to fire both 5.56 NATO and .223 Remington, the most commonly used round designed for the AR-15 platform.

It contains the same elements as 4150 steel. It also contains Vanadium. Vanadium significantly increases the strength, hardness, and high-temperature stability of the steel.
Finish: Phosphate - Manganese Phosphate finishes are used on barrels to protect against corrosion and wear. Manganese Phosphate finished is considered for its toughness, and is used in multiple different applications such as aerospace, ordnance, and other firearms-related parts.
