I'm in the planning stages in building my first speargun. What are some websites that offer parts? I know of Aimrite and Neptonics, but I'd like to reasearch others. Also, do Neptonics trigger mechs work with Aimrite handles?

Try this site.

Ted has a lot of information on building your own gun. He also offers kits, stocks and plans.

Hey Jim are you stocked there already?

Spearotiki guns are too beautiful to shoot! Unbelievable craftsmanship...
