Never Unarmed Professional .625 Caliber Blowgun 4 Foot One Piece Alumium Black. The Never Unarmed 4 Foot Professional Big Bore Blowgun comes with a mouthpiece, rubber ferrule, dart quiver, and 36 darts (6 Stun Darts, 15 Mini Broad Head, and 15 Bamboo). Large caliber blowguns like the .625 Magnum have an effective range out to 20 yards or more. With practice, a skilled user can hit a two-inch circle at amazing distances, delivering a heavy weight dart. That's a payload easily capable of penetrating a half-inch sheet of plywood. Accuracy and range like this enable an experienced hunter to take small game like doves, quail, squirrels and rabbits in complete silence without danger of over penetration or errant darts striking livestock or humans in the distance. Shooting a blowgun is great fun. It is an activity that can be enjoyed indoors or out, in sunny or inclement weather. Skill with a blowgun can lead to many inexpensive hunting adventures and stand you in good stead in survival or self-defense situations. The Professional model come with a target style mouthpiece and a 3mm thick barrel. Yep! That makes them almost twice as thick, and 45% heavier than Never Unarmed's standard model and clinches their title of heaviest, commercially made blowguns in the world.
