These adaptors while manufactured in volume they are basically custom made. They are made from 416 stainless steel and then heat treated to our specifications. TuffHead and Abowyer worked together on this project in the development and testing.
A project like this can get pricy for development. Together we were able to share the mutiple drawing and machine set up cost and get reasonable volumes for a production run.
Larry and i both tested the adaptors independently and were thrilled with the test results. We are so confident in the product all Tuff-Adaptors come with a life time warranty against bending and damage.
The stainless steel "TuffAdaptors" are offered in the normal or standard screw in configuration in 75 ,100 and 125 grain.
The" Tuff Extended Adaptors "as shown in the original post come in 150, 175 and 200 grain.
The beauty of the ""Tuff Extended Adaptors is they can be used in connection with a footing to make a extremely strong setup addressing the famous weak spot of all arrows.
The extended adaptor can be used with all brands of glue on broadheads that use the AMO standard taper to add weight and FOC .A great way to easily vary FOC while experimenting .
The adaptors are packaged three per package and sell for $9.00 to $9.75 per package.The can be purchased at either web site.
