The designs offered in this complete guide represent the stubborn persistence of a military ordnance man who undertook the project simply because they said it couldn't be done.
The project developed into a small Class II manufacturing business, which sold the converted 10/22's in most of the states where they are legal to own. To date, after at least 100,000 rounds fired, there is yet to be a parts failure, Ruger's or the manufacturer's.
It is not difficult to design a drop–in automatic sear, to trip it and bypass the trigger sear to allow the 10/22 to, theoretically, cycle automatically.
This guide details the complete set of instructions for converting a Ruger 10/22 to full–auto select fire.
