2. Setup and Installation
Proper installation of your Magnus Stinger broadheads is crucial for safety and performance. Always handle broadheads with extreme care due to their sharp blades.
2.1 Attaching to Arrow Shafts
- Inspect Arrow Inserts: Ensure your arrow shaft inserts are clean, free of debris, and securely glued into the arrow shaft. Any looseness can affect broadhead alignment and flight.
- Thread Broadhead: Carefully thread the Magnus Stinger broadhead onto the arrow shaft insert. Turn clockwise until it is hand-tight. Do not overtighten, as this can damage the insert or broadhead.
- Check Alignment: Visually inspect the broadhead to ensure it is perfectly aligned with the arrow shaft. There should be no wobble or crookedness. Misalignment can lead to poor flight and reduced accuracy.
- Blade Orientation (Optional): For optimal flight, some archers prefer to align the broadhead blades with the fletching of the arrow. While not strictly necessary for the Stinger's flight, it can be done by slightly loosening and re-tightening the broadhead until the desired alignment is achieved.
2.2 Safety Precautions
- Always use a broadhead wrench or similar tool when handling broadheads to avoid direct contact with blades.
- Store broadheads in a protective case when not in use to prevent accidental cuts and blade damage.
- Keep broadheads out of reach of children and pets.
3. Operating and Usage
The Magnus Stinger broadheads are designed for hunting and target practice with appropriate targets. Always ensure you are using them in a safe and responsible manner.
3.1 Pre-Shot Inspection
- Before each shot, inspect the broadhead for any damage, dullness, or looseness. A damaged or dull broadhead can compromise performance and safety.
- Ensure the broadhead is securely fastened to the arrow shaft.
3.2 Shooting Considerations
- Practice: It is highly recommended to practice with your broadheads or broadhead-tuned field points to confirm arrow flight and accuracy before hunting.
- Target Selection: Use targets specifically designed for broadheads to prevent damage to the broadhead and ensure safe arrow retrieval.
- Ethical Hunting: Always adhere to local hunting regulations and ethical hunting practices. Ensure a clean, humane shot.
4. Maintenance
Proper maintenance extends the life and effectiveness of your Magnus Stinger broadheads.

4.3 Cleaning and Storage
