The 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.

Please note, we do have a number of available upgrades and services to offer with these barrels, and more information can be found about them under the SERVICES section of our website, listed at the top/header of the page.

Core barrel
The Core barrels are the best at their price point and as good as others that cost more. This makes 3 Core barrels that I have. They're my go-to. The real winner here is the customer service by Capable of the best in the business.... always shop with confidence.

Sub-Minute Outta the Box
Barrel has been fantastic. Break-took maybe 20 rounds. Shoots sun minute out of the box with both 55gr and 77gr factory ammos. Capable Citizen was also great. Did a fine pin job on the VLTOR gas block, confirmed the gas port at .077+” and did a great job polishing feed ramps. Would definitely recommend this barrel and this dealer to anyone.
