Expandable Broadheads for Sale
Discover premium expandable broadheads from the industry's top brands including Rage, G5, BEAST, Swhacker, Magnus, NAP, Slick Trick, Muzzy, and more. These mechanical broadheads deliver flight-like-field-point accuracy with devastating on-impact blade deployment, creating massive wound channels and superior blood trails for quicker, ethical harvests on deer, elk, and big game.
Popular models like the Rage Hypodermic, G5 Deadmeat, Swhacker Levi Morgan series, Slick Trick Viper Trick, Magnus Black Hornet (expandable variants), NAP Killzone, and Muzzy Trocar feature rear-deploying or hybrid designs with 2"+ cutting diameters, razor-sharp stainless steel blades, and reliable shock collar or band retention systems for fail-proof performance.
Deployment Mechanics and Kinetic Energy Retention
- Preserve downrange velocity by utilizing streamlined, low-profile closed blade profiles in flight.
- Generate massive entry wounds with rear-deploying slip-cam systems that slide open smoothly.
- Prevent premature in-flight opening on high-velocity crossbow platforms using rigid collar tension systems.
- Ensure structural integrity through heavy bone impact with hardened aluminum and titanium ferrules.
Selecting high-performance expandable broadheads requires matching blade mechanics to the kinetic energy output of your specific bow setup. Unlike fixed-wing designs, mechanical heads fly with target-point aerodynamics because the cutting edges remain tucked tightly against the ferrule during flight. This streamlined profile eliminates the wind-planing common with wide hunting setups, allowing archers to maintain precise accuracy out to extended distances.

Frequently Asked Questions
What is the minimum kinetic energy required to shoot expandable broadheads effectively?
Most standard mechanical heads require a minimum of 55 foot-pounds of kinetic energy to ensure full blade deployment and complete pass-through penetration on deer-sized game. Sub-atomic setups or ultra-low draw weights can shed forward momentum too quickly upon initial impact.
How do rear-deploying blades differ from over-the-top mechanical designs?
Rear-deploying configurations utilize a slip-cam system that slides the blades backward into position upon contact. Over-the-top models require the front point to enter the tissue first before the levers catch the skin, and deployment begins.
Why do high-velocity crossbows require specialized mechanical broadheads?
The extreme forward acceleration of a modern crossbow can exert enough inertial force on standard broadhead blades to snap them open mid-flight. Crossbow-specific models feature heavier retention springs, stiffer dental bands, or specialized indexing collars.
Do mechanical hunting heads require standard paper tuning at the pro shop?
While these heads closely replicate field-point flight out of the box, your bow must still be perfectly paper-tuned to ensure the arrow strikes the target completely square.
How do practice heads differ from actual hunting mechanicals?
Practice heads are solid metal replicas that precisely match the weight and aerodynamic profile of a closed mechanical broadhead. They allow you to shoot repeatedly into standard foam archery targets without damaging real deployment blades or dulling razor edges.
