Wasp Jak-X 100gr Expandable Broadhead - 3 Pack - The JAK-X is a crossbow mechanical broadhead designed to best meet the demands of serious hunters. The Stainless Steel Smart Tip (SST) is pre-aligned with three stainless steel blades ensuring maximum penetration by creating a straight cutting path through anything that gets in its way. The dual O-ring system retains the blades during flight and guarantees proper deployment on impact, even when the mechanical broadhead is shot from crossbows at 380+ FPS. Upon impact, the blades of the broadhead fold back to a huge cutting diameter of 1-3/4 in, resulting in quick kills and easy-to-follow blood trails.The Jak-X should be used with 2 O-rings. Six (6) extra O-rings are in the package. Three (3) broadheads per pack.
