This new head was created after many requests for a heavy weight single bevel broadhead. All steel construction and the single bevel head design make this one incredibly tough head. The right grind single bevel design is proven for bone busting and increased tissue damage. All heads come with our patented Modular Weight System (25 grains).Blade - 420J2 Stainless Steel & Teflon coated. 1 3/16" main blade, 5/8 " bleeder blade. .051" blade thickness. Ferrule - Stainless Steel. Note: Single bevel heads may require a bit more tuning than double bevel broadheads.
