X-Act Mechanical BroadheadThis 100 grain, 1- 7 /16" cut broadhead is designed for the hunter who wants maximum velocity from their crossbow but refuses to accept less than outstanding accuracy. The X-Act broadhead’s “Clip Loc” blade control system holds blades securely during a crossbow’s explosive acceleration eliminating the need for “O-rings” or rubber bands, but deploying the blades reliably on impact.
