Amazon sells them... there are two different ones... one where the force of the bands will open the metal posts when the trigger is pulled, and the other that opens the posts when the trigger is pulled which costs a lot more than the first one.
Looks like you got a big order for these in the comments. If you could make the full setup trigger slingshot and all you would make alot. I would check on a patent if not already
Thatts awesome! Very nice design. I made my first sling shot fifty years ago.I used dishwashing gloves for slings and sealskin for leather .Tied them with caribou sinew,thread .thankyou
