Overview

Built for crossbow hunters running high-speed setups, this broadhead is designed around a mechanical 2-blade design and the patent-pending Speedlok system, which does not rely on O-rings, springs, clips, washers, or collars. It is intended for crossbows delivering 500+ FPS and is described as perfectly balanced and spin tested for field-point accuracy. The heavy-duty 420 stainless steel blades are listed as 50% thicker than average expandable broadheads, while the aircraft-grade aluminum ferrule and stainless steel tip add to the package. Sold as a 3-pack, it suits hunters looking for a purpose-built option for big game use with modern high-velocity crossbows.

Pros

  • Two-blade mechanical design keeps the broadhead simple and purpose-built for crossbow hunting.
  • Heavy-duty 420 stainless steel blades are listed at 50% thicker than average expandable broadheads.

  • Perfectly balanced and spin tested for field-point accuracy.

Considerations & Trade-offs

  • Designed specifically for crossbows delivering 500+ FPS, so it may not be the right fit for slower setups.
  • This is a 2-blade mechanical broadhead, which is a different setup than fixed-blade or multi-blade options and may require a hunter’s preferred tuning approach.
  • The SpeedLok system is built to avoid O-rings, washers, and collars, but that also means it uses a proprietary retention design rather than a more familiar expandable setup.
  • Pack includes 3 broadheads, so it is a relatively small quantity if you want multiple ready-to-go replacements.
