Criterion Barrels 13.9" .223 Wylde Core Phosphate/Chrome-Lined Midlength Barrel 1:8 Twist - 15130-CR8
Only 7 left in stock
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.

Excellent shooter
This was my first Criterion barrel. The profile is excellent, and headspacing was perfect. The m4 ramps (aka the barrel extension) were spot on - everything was in spec. After sighting it in with PMC 55gr 5.56 (my competition ammo), I was able to get consistent 1.5 MOA groups (excellent for the ammo used). With 77gr IMI Razor Core I was able to consistently get sub MOA 5 round groups (usually .8 or .9). All of this was done with a lower back pressure can as well. To test, I also ran 60 rounds through it very quickly to heat it up, and then tested groups afterwards. They barely opened up at all. My barrel is an excellent shooter, though I don't know how common this is (n=1) - though, obviously, I don't think it is that abnormal for a Criterion barrel.

Been patiently waiting for this barrel and jumped on it when it came in stock (briefly). Shipped fast. Haven’t installed yet but outstanding quality for sure.
