Our cold hammer forged barrels are known to be as accurate and long lasting as any you'll find. And now, you can easily switch the caliber of your DELTA 5 with this barrel conversion kit. We've taken the modularity found in our ARs and adopted it for the bolt-action rifle by attaching the barrel via a barrel extension. Since the extensions are installed by us at our factory, headspace will always be correct because it is set at the time of manufacturing. To change barrels, all you need to do is remove the barreled action, remove the barrel nut, install the new barrel, tighten the barrel nut to the proper torque and then re-install the entire barrel/action assembly into the stock. With the included 1/2" barrel nut wrench, you can swap barrels in minutes. No gunsmith required!
