Before you ask for files, please be patient! OOB is still an unsolved issue in this design. This is a proof of concept that 3 position FRT can be done within the stock MP5 22lr trigger pack. I still have concerns for the longevity of the 3D printed parts under live fire condition. I’m looking into metal components for this project. Nevertheless, we did it!
