Professional .625 Magnum® Big Bore® Blowgun, 4 Foot Cold Steelaposs Big Bore® Blowguns feature large caliber .625 Magnum barrels that make them capable of shooting darts that are faster and heavier than other models on the market today! They have an effective range out to 20 yards (abt. 18 m) or more and, with practice, a skilled user can hit a two-inch circle at amazing distances and deliver a heavyweight dart capable of penetrating a half-inch sheet of plywood. While the regular .625 Magnum® blowguns are awesome, Cold Steel decided to raise the bar even higher with theProfessional .625 blowgun. It comes with a target style mouthpiece and a 3mm thick barrel, which means it is almost twiceas thick and 45% heavier than the standard models, making it the heaviest commercially made blowgun in the world. But the realreason you should shell out the extra dough for it is the huge increase in accuracy afforded by its substantially more rigid barrel. Professional .625 Magnum Big Bore Blowgun, 4 Foot (approx. 1.2 m) 3mm wall thickness Including mouthpiece, rubber ferrule, dart quiver, quiver guard and 36 darts (15 bamboo darts, 15 mini broadhead darts and 6stun darts).
