The 3" Bronco® Vane (formerly called the 3" Parabolic X Vane™) is an incredibly versatile vane. We recommend it for compound and recurve archers shooting indoor spots, and it is NASP approved. The 3" Bronco Vane performed exceedingly well on crossbow bolts during Bohning's comprehensive field testing, and for traditional archers looking for a profile similar to feathers but with superior durability, the 3" Bronco Vane is a great option! The 3" (76.2mm) Bronco Vane measures 0.43" (10.9mm) in height and weighs an average of 8.5 grains (388.8 mg). Like all Bohning vanes, the base of the 3" Bronco Vane is pre-primed for optimal adhesion. Proudly manufactured at the Bohning Factory in Lake City, Michigan, United States.
