Criterion Barrels Introduces CORE Series for AR-15

Criterion Barrels has launched a new AR-15 barrel profile that they are calling their CORE series. The barrels feature a continuous taper from front to rear. The muzzle end is similar in diameter and weight to a government contour but the barrel tapers wider toward the breech end. This results in a barrel that is relatively light in weight, balances well, and that has enough material where necessary to deal with heat.

Criterion states:

Our CORE Series barrels are designed with tactical shooters in mind. These barrels are built to address issues with weight distribution, balance, and handling of traditional profiles, while increasing performance through consistent harmonics and uniform heat dissipation.

The CORE Series feature a modern, continuous taper profile that eliminates steps and harsh variations in diameter. The steel is redistributed where it is needed most: surrounding the chamber. Added weight over the chamber absorbs heat evenly during hard use and moves the balance of the rifle closer to the body for increased control. This is optimal for maintaining balance when used with modern accessories like Low Power Variable Optics (LPVO’s), weapon-mounted lights, suppressors, clip-on night vision devices, and IR lasers; these components boost the capabilities of the rifle, but can hinder the shooter’s performance by increasing front-end weight. The front end of the CORE Series remains light and fast for better handling, balance, and speed.

The CORE Series helps you handle real-world applications by maintaining exceptional performance and rugged reliability during hard use. These barrels work for you wherever mobility is a priority and performance is essential.

The CORE series barrels are available with rifle length gas in 18″ and 20″ lengths. They are also available with midlength gas with 13.9″, 14.5″ and 16″ lengths. Finally, they are available with carbine length gas system in 10.5″, 11.5″, and 12.5″ lengths. All CORE series barrels are made from 4150 CrMoV steel, chrome lined, with a 1 in 8″ twist, and a Wylde chamber.


Criterion AR-15 300 Blackout 10.5″ Hybrid Barrel

Criterion is now offering a new AR-15 300 Blackout 10.5″ Hybrid Barrel. See the video and description below for more details.

The 10.5” Hybrid barrel is ideal for the versatile 300 AAC Blackout cartridge. Paired with a 1-7 twist, the 10.5” can stabilize a wide range of BOTH subsonic and supersonic bullets. If you plan on using a suppressor, it will also ensure subsonic loads are not pushed beyond the supersonic threshold.

Our Hybrid contour is the ideal balance between weight and intelligently distributed barrel material for excellent heat absorption and harmonics; maintaining a consistent point of impact even through hard use and rapid strings of fire. Compared to shorter barrels, the 10.5” allows for handguards long enough to mount a variety of lights, lasers, tape switches and back up sights, while still allowing room to grip and use the rifle.
