Does anyone have a drawing that they could post. I would like to try and make one.

Thanks

When I made mine I got all the demensions off of the brownells website from there wrench. The other needed dimensions I got off of a receiver. Look through the previous post this topic came up recently with pictures. I can measure mine for you if you need a particular measurement.
