Criterion Core 14.5″ .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.
FEATURES:
- Chrome-lined for superior barrel life and corrosion resistance. Our chrome lining process is the most refined in the industry and will not degrade accuracy.
- .223 Wylde chamber that is designed to safely and reliably fire both .223Remington and 5.56NATO ammunition while increasing accuracy due to more consistent chamber pressures.
- Honed and hand-lapping rifling produce perfect bore uniformity and a pristine internal finish that aids in barrel cleaning and is paramount for accuracy
- Finely polished chambers for reliable extraction and feeding
- Gas port tuned for proper function with and without suppressor
- Precision-machined barrel extension and M4 feed ramps

I love Rooftop Defense. They seem to have stock of items when no one else does, and their prices are great. Got a 14.5 criterion barrel, gas block, and gas tube combo. Everything came quick as I could expect and shipping didn’t add a billion dollars. Quality products, arrived safe and without damage.
They even send you a meal to with your purchase lol.

I grabbed a 14.5″ criterion core mid gas for a general purpose build. I already had a Ballistic advantage premium series 416 stainless fluted spr barrel that is about 1 moa and to my surprise this much thinner criterion core barrel shoots groups every bit as tight as the medium profile spr barrel. I’m gonna grab at least one more criterion core barrel, they are impressive.

You already know how good this barrel is as it’s reputation speaks for itself. The only question I had is ” how good is rooftop defense?” Happy to say they had my barrel shipped out the day after I placed my order ” ordered it after hours”. I will be grabbing another one from rooftop defense very soon.

Really wanted to love this barrel. It was pretty accurate for a CL barrel and the fit and finish looked great. Mine had an issue with the chamber though. Popped primers on som LC M193, IMI M193, IMI Razorcore 77gr, and some 77gr handloads. Unfortunately it was pinned and welded so I don’t think I can send it back to Criterion for warranty.
