The Mangle EXP "Expandable" is the most technologically advanced broadhead on the market. On impact, the point will enter into the animal until expanders make contact with the hide which will activate the opening of the surgically sharp 420 stainless steel blades. These .040" thick scalpel sharp blades will bypass the hide and rib cage before opening to create an extremely massive wound through the vital organs. As the Mangle EXP continues its path the aft section of the blades will then make contact with the hide and its 1 1/2" cutting diameter will create a wound that can only be described as maximum carnage. The frame is constructed of 7075-T6 Aircraft Grade Aluminum that is 1.5 times stronger than most other brands of Broadheads on the market today using 6061 Aluminum. The extra strength of the 7075-T6 frame will maximize durability for multiple kills and with easy to replace blades. You will be able to get several years of carnage out of them. Our blades are constructed of 420 Stainless Steel and hardened for extreme use.
