The Magnum Research Desert Eagle Barrel (brand part no. BAR446CH) is a 6-inch, .44 Remington Magnum accessory barrel built for the Desert Eagle Mark XIX, finished with a color case hardened treatment that gives the steel a mottled, heat-tempered look unlike any coated finish. Made in the USA from all-steel construction, the barrel carries a Weaver-style Picatinny accessory rail along the top for mounting an optic, and it’s cut with 6 vent-style slots along its length that add to its distinctive appearance. Like every Mark XIX barrel, it installs directly onto a compatible frame, letting a Desert Eagle owner add a case-hardened barrel option without buying a second pistol. It retains the Desert Eagle’s fixed front sight for use without an optic mounted. It’s built for Mark XIX owners who want a barrel finish with genuine heat-treated character rather than an applied coating.
