Exchange barrel for Dentler DR21 with base rail base or base Vario with muzzle thread M15x1.
Thanks to the innovative design, the total length of the straight-pull repeater in mini and standard calibers (barrel length 520 mm each) is only 870 mm. In the magnum caliber, the barrel length is 600 mm. Changing barrels is possible without any problems while maintaining the same point of impact. The replacement is done with a screw.
