ELD Performance AR-15 16" .458 SOCOM, .875 Gas, 1:14T, Government Profile, 4150 CrMoV Barrel

General Barrel Info: The barrel 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. Barrels come in four different specifications for gas systems, Pistol, Carbine, Mid-Length, and Rifle. Barrels vary between profiles as well as from Government, to Heavy, and Slim. Thanks to the modularity, you can choose different calibers starting with the barrel, each with its specific twist rates. Choosing your barrel for your next build has never been easier.

About This Barrel: This barrel is 16-inches long and chambered for .458 SOCOM. It operates on a carbine gas system and has a 1:14 twist rate. This government profile barrel is made from 4150 CMV with a nitride finish which makes it strong, durable, and incredibly reliable. For your next .458 SOCOM build you will want to consider this barrel.

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: .458SOCOM - This barrel is chambered in .458 SOCOM, a big-bore cartridge originally developed from .50 Action Express. .458 SOCOM was designed to be used on the AR-15 Platform to deliver more ballistic energy on impact at supersonic speeds. .458 SOCOM can be used with a standard buffer, buffer spring, & STANAG magazines.

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: 5/8x32 - Common on .450 Bushmaster and .458SOCOM barrels this threading will allow the addition of blast cans, flash hiders, compensators, and other muzzle devices.
