Constructed from uniform ACU-Carbon material, these 5mm shafts feature a straightness tolerance of +/- .003 inch and a 0.204-inch internal diameter, delivering consistent spine and high-impact performance. Each 32-inch shaft includes 25 grain aluminum 8-32 half-outs and 9 grain 5mm X Nocks, optimizing strength and front-end durability. This 12-pack is ideal for building high-performance hunting arrows and is compatible with additional component upgrades like brass and steel half-outs or Match Grade HIT Collars.
