Criterion Core 16″ .223 Wylde Midlength Barrel, 1:8 Twist
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.
Criterion’s 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.

It’s a criterion barrel. If you found this product then you should already know it’s reputation. My review is for Rooftop Defense. Rooftop not only had the barrel I was looking for in-stock, whereas Criterion is always on backorder, but I received it in the mail just 2 days after ordering. Huge props to Rooftop for the fast order processing and shipping times.

First purchase from rooftop defense, I’m very happy with my purchase. I chose Criterion because Pro 3 gunners recommended them, so when I decided to make a competition rifle, I finally got the barrel; rooftop recommended the gas block and tube which made that part of it simple. Install was also a breeze, the barrel is dimpled so there’s no guessing when aligning with the gas port, definitely recommend a reaction rod to assemble. I was eagerly waiting for the barrel to show up so I could finish the build, so I had it out on the range within hours to test it out and it ran flawlessly. Produced some very nice groups but I wasn’t even doing my best work shooting since I was trying to decide on a bullet weight; from what I have, it shot 62grain very well; I needed a rifle that’s accurate with economy grade ammo and this barrel did just that. The balance of the barrel that’s a feature of the Core barrels is noticeable as well! It’s not a featherweight rifle but I was still able to shoot unsupported out to 100 with relative ease!
