Here is my built from the ground up of a RDL Jackal autococker by Jackal Machine. As you can see the milling has removed most all but the necessary metal needed on the body and blocks. In my opinion Jackal cockers are among the best looking and performing cockers available. But to each their own.
-The first set of pictures are the latest. The second set had an E1 with Zero B and no mQ valve.
