The MAKO by Simmons is exactly what the Chief ordered. The MAKO broad head comes in a 3 pack and is 1.5" tall by 1.25" wide and weighs 100 grains. This small blade in almost unbelivable. It has a bleeder blade that makes short work out of tracking. We've done a lot of testing here at Chiefs Trible Workshop and then we did the ultimate test. We tested it on one of the biggest animals in North America , The Great American Buffalo. Not only did it take the Buffalo down but it made a complete pass thru. The MACO teamed up with the VAP arrow is the PERECT combination to use in your Sling Bow. They fly straight and true. Almost unbelievable what this small broad head will do, but then look at the Sling Bow. Like the Chief says a lot of times "powerful things come in small packages"
