This Magnum Research .429 DE replacement barrel (brand part no. BAR4296SRMB) is a 6-inch stainless steel barrel built for the Desert Eagle Mark XIX, not a complete pistol on its own. It carries an integrated Picatinny rail for mounting an optic, a fixed front sight for iron-sight use, and an integrated muzzle brake to help tame recoil in the powerful .429 DE chambering. A 1:18-inch twist rate stabilizes .429 DE bullet weights, and the stainless construction resists corrosion better than a standard blued finish.
