Here is a Striker I got form Ron this past Weekend along with a wingbone call he donated for out veterans hunt. Super nice guy, and excellent craftsmanship.
The call and the striker both sound great, and yes the bone head of the striker is weighted by being filled with epoxy.
Nice!!
Here are some examples of Ron's work.
