How do you make a speargun?

Making a speargun involves several steps and requires careful attention to safety and design. Start by selecting a suitable wooden or aluminum stock for the gun body, ensuring it's sturdy and comfortable to hold. Attach a trigger mechanism and a line release, then add a muzzle to hold the spear and rubber bands for propulsion. Finally, ensure all parts are securely fastened and test the mechanism before use, prioritizing safety at all times.
