ELD Performance LR-308 18" .308 WIN Barrel
General Barrel Info: The barrel on an LR-308 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. LR-308 Barrels come in four different specifications for gas systems, Pistol, Carbine, Mid-Length, and Rifle. LR-308 Barrels vary between profiles as well as from Government, to Heavy, and Slim. Thanks to the modularity of LR-308, you can choose different calibers starting with the barrel, each with its specific twist rates. Choosing your barrel for your next LR-308 build has never been easier.
About This Barrel: Avid fans of long-range shooting need to take a look at this barrel. This 18-inch barrel made from 41V50 steel is chambered in .308 and has a stainless steel barrel extension. The 41V50 steel helps to add strength and heat resistance to this barrel. It features a nitride finish that adds to its durability and has a 1:10 twist rate. Shooters looking to do big game hunting or long-range shooting will want to go with this medium-profile barrel.
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.
Barrel Classification: Rifle
Length: This Barrel is designated as a rifle barrel with an overall 18" length.
Caliber: .308 WIN - This barrel is chambered in .308 Winchester otherwise known as 7.62x51 NATO. .308 Win is the standard caliber for LR-308/AR-10 rifles of old & modern battle rifles from the 70s onward. Featuring amazing long-range accuracy and energy delivery, 308 Winchester is the most common hunting and long rifle round in America.
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: 5/8x24 - 5/8x24 Threads are commonly found on barrels chambered in .30 Cal and up. Usually .308 Win, .300BLK, 6.5 Grendel, 6.5 Creedmoor, and 7.62x39. Muzzle Devices such as flash hiders, blast cans, and compensators will work with this barrel.
Barrel Extension Finish: Stainless - Stainless steel finishes come in high-luster finishes similar to nickel plating, but with the added benefit of increased strength and corrosion resistance. Stainless steel finishes do not experience the same wear that other metals may experience such as peeling, flaking, wear and rust from scratches where the oxidation protection layer may be removed.
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 .750 Gas Block Journal. .750 Gas Block Journals are standard for AR-15 barrels chambered in .223 Remington, 5.56 NATO, and .300 Blackout. This Gas Block Journal is known for its reliability it assists the rifle function in regular and adverse conditions. 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 an average .750 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.**
Recoil Technologies "Marder" 5/8x24 .308 Nitride 4-Slot Muzzle Device
Having a muzzle device on your gun makes it way more controllable! There are other key reasons to add certain devices to your gun. The recoil, muzzle rise, sound, flash, and the amount of the blast felt upon firing are all significantly reduced. In some cases, the right muzzle device can cut these in half. This can make larger calibers like the increasingly more popular .308 Winchester's recoil more manageable. With lower recoil and muzzle rise, you'll be able to make follow-up shots more quickly and precisely. If you shoot a weapon under 20 inches long, and you want to be able to see after firing at night. Then some type of flash hider is a must. Flash cans also come into play when trying to reduce the blast felt upon firing your weapon.
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: 5/8x24 Threads are common for muzzle devices made for .30 caliber projectiles and above, most commonly used on .308, 7.62 NATO, .300 Blackout, 7.62x39, 6.5 Creedmoor, & 6.5 Grendel.
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.
