Mercury Precision 'Astroid' 16.25" 7.62x39, Carbine Gas, 1:9.45T, 41V50, Stainless Extension, Nitride Barrel Finish, .750" Gas Block Journal

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 scientists and engineers have been hard at work in the workshop and laboratory creating AR products that are out of this world. The end result of this brain trust is a firearms brand simply known as Mercury Precision. The goal with Mercury Precision was to create high-end products that do not require a space travel budget to afford.

About This Barrel: This Mercury Precision 'Astroid' barrel is 16 inches long and operates on a carbine gas system. The combination of 4150 CMV with a nitride finish makes this barrel durable and reliable. It comes with a stainless steel extension and has a 1:9 twist rate which is good for stabilizing lighter and mid-weight bullets between 45 and 77 grains. This barrel has a classic design that works well with your next 7.62x39 build.

Barrel Classification: Rifle

Length: This Barrel is designated as a rifle barrel with an overall 16.25" length.

Caliber: 7.62x39 - 7.62x39 Is the most common AK platform caliber adapted for the AR-15 platform, this barrel will allow reliable feeding and operation with the 7.62x39 cartridge.

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.


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 .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.**


5/8x24 Thread Spiral fluted Muzzle Brake

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:

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:

Chambers: *Muzzle Brakes only - This Muzzle Brake has chambers to catch the expanding gasses and divert them to the sides of the shooter, reducing recoil and increasing controllability.

Ports: This Muzzle Device has ports to compensate for the felt recoil and reduce muzzle climb by pushing the barrel back down, making the shooting experience feel flat without jumping off target.
