This is a target clip intended on being used with ½ inch rebar, but works with any half inch round stock or threaded rod as well. I t works by the round secton clipping onto the rebar, and the flat clip clipping onto either a cardboard target or just a flat piece of board like pictured with a paper target taped to it.
The idea and origional design this was based on was from Hoffman Tactical and can be found on Odysee. His design was for 3/8 inch rebar. This model was fully designed by me but I pulled aspects of his model and just remodeled them.(I find it easier to redesign from sketches than use mesh to remix)
