Grim Reaper Broadhead Xbow Mechanical 2-blade 100gr 2''cut. With no snag point the GR XBow can be used on all types of crossbows regardless of draw weight or kinetic draw force. To increase penetration and longevity the GR XBow mechanical broadheads feature an advanced o-ring retention system which requires the mechanical broadheads to be assembled on a conventional bow rather than a crossbow. To aid in the o-ring retention process we utilize a stainless steel spring that has been hardened to ensure maximum durability. Unlike many mechanical broadheads on the market today the GR XBow mechanical broadheads have a one piece stainless steel ferrule that is inserted into the o-ring allowing the XBow mechanical broadheads to be significantly less dependent on gravity for reliable deployment. Another great feature of the GR XBow mechanical broadheads is its reusable feature. Once the o-ring is open the mechanical broadheads lock open feature that must be manually operated. Once the o-ring is open the mechanical broadheads locking mechanism will lock the blades in place ensuring that the XBow mechanical broadheads stay fixed in the open position. This feature also allows hunters to reuse the broadheads without having to recycle the o-ring. Please recycle your broadheads and never store or use them.
