ELD Performance 16" .458 SOCOM 1:14T Government Profile

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.

Gas Block

The Gas Block on your AR-15 / AR-10 style rifle is an integral part of the gas system that allows your rifle to cycle. By tapping off gas from the barrel and diverting it back into the gas key of the bolt carrier group, there is enough inertial force to unlock the bolt carrier, send it rearward to the recoil assembly, and extract and pickup another cartridge to fire.

About this Gas Block: This gas block is machined with a .875 Gas Block Journal. .875 Gas Block Journals are found on both AR-15 barrels chambered in .223 Remington, 5.56 NATO, and .300 Blackout; and AR-10 barrels chambered in .308, 7.62 NATO, and 6.5 Creedmoor. This Gas Block Journal is known for its reliability it assists the rifle function in regular and adverse conditions. .875 Is larger than standard .750 gas blocks and will tap more gas off from the barrel. This gas block has a 'low-profile' design and is made to fit underneath a free-float handguard.

Gas Block Journal Size: This gas block is a larger than average .875 size gas block.

Platform: This gas block will work on both AR-15 and AR-10 barrels, for .308 and 6.5 Creedmoor barrels, be mindful of possible tolerance issues in the barrel profile.

Profile: This Gas Block is 'low-profile' and designed to fit underneath freefloat handguards.

Finish: Phosphate - This gas block uses a phosphate finish, making it have improved rust and corrosion resistance. Phosphate finishes typically make the part have a matte finish.

Attachment Style: Slide On - This gas block has a fixed size and must slide on from the front of the rifle and is secured in place with 2 set screws near the bottom.

Material: Steel - This gas block is made from hardened & tempered steel, providing the strength and rigidity to withstand forces of expanding gasses and vibration from the rifle or pistol under operation.

DISCLAIMER: **Before purchasing, please be mindful of possible tolerance differences resulting from your handguard profile, barrel profile, gas length, and barrel Gas Block Journal.**

KAK Industry 5/8x32 .450/.458 Phantom Style 4 Port Muzzle Brake

The .450 Bushmaster and the .458 SOCOM are both very powerful rounds, and if you know anything about the comparable .45-70 Government, you know that they can deliver quite a lot of recoil, noise, and muzzle rise. By looking into a muzzle device with a 5/8x32 thread to fit these guns you can utilize these two rounds while feeling less recoil, hearing less noise, and being able to return to target quicker.

About This Muzzle Device: Flash Hider - A flash hider is exactly what it sounds like. This muzzle device is designed to hide the flash of your rifle. While modern-day ARs and ammo are designed to burn as much gunpowder as possible, it doesn't always happen that way. Sometimes, there is remaining powder burnt causing the visible flash out of the end of your weapon. A good flash hider, although not able to completely remove the flash effect. Can significantly remove the flash from the end of your barrel.

Threading: 5/8x32 is the most common thread type for .450 Bushmaster and .458 SOCOM

Finish: Manganese Phosphate - Manganese Phosphate finishes are used on barrels to protect against corrosion and wear. Manganese Phosphate finish is considered for its toughness and is used in multiple different applications such as aerospace, ordnance, and other firearms-related parts.
