General Barrel Info: The barrel on an AR-15 originally operates under a 'gas impingement' system' by tapping gas off of the barrel and cycling it back through the gas system to assist the bolt carrier in unlocking and extracting the spent cartridge. AR-15 Barrels come in four different specifications for gas systems, Pistol, Carbine, Mid-Length, and Rifle. AR-15 Barrels vary between profiles as well as from Government, to Heavy, and Slim. Thanks to the modularity of AR-15, you can choose different calibers starting with the barrel, each with its specific twist rates. Choosing your barrel for your next AR-15 build has never been easier.
Brand Info: The Engineers at ELD Performance have created a line of high-quality barrels precision machined for reliability and accuracy at an affordable price! ELD Performance barrels are made in a variety of calibers with the reliability to rival the best.
About This Barrel: This 4150 CMV barrel has a 1:8 twist rate which provides an advantage to shooters who are looking for a more universal barrel. Itâ€™s crafted from 4150 CMV which is Mil-Spec gun steel that does a great job handling heat which helps it maintain its accuracy. The nitride finish increases the barrel's durability and makes it less susceptible to corrosion. This barrel has a carbine gas system and is dimpled to allow for easy and secure gas block installation and alignment.
About the Profile: Government - The government barrel profile is lightweight under the handguards, until just before the gas port. After the gas port, it gets heavier, out to the muzzle.
Barrel Classification: Rifle
Length: This Barrel is designated as a rifle barrel with an overall 16" length.
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.
Material: 4150 CrMoV - Chrome-Moly Vanadium, or simply "CMV", is the official mil-spec gun steel developed by Colt Firearms for the military-issued M16 and M4. 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: Nitride - Nitriding is a process during manufacturing that diffuses nitrogen into the steel to make a case-hardened surface for improved resistance and strength. A Nitrided barrel typically has a gloss black texture.
Thread Pitch: 1/2x28 - This threading is commonly found on barrels chambered in 5.56, .223, and .224. This will allow the installation of most muzzle devices such as flash hiders, blast cans, and compensators threaded to 1/2x28 threads.
