Charging Handle for AR-15 and M16 - Milspec

AR-15 and M16 milspec charging handle, modified to use a standard pen spring and a paperclip at the pin. This works in an AR-15 and actually stood up to being racked a couple dozen times, when printed in PLA+. It could probably be actually usable in PETG or something else. It does have a lot of flex but it seats and latches very well. This is published mostly to open-source AR-15 and M16 parts in order to move firearm fabrication back into the hands of the people. Read the .docx document to learn how to print and assemble. You need to do some complicated things with supports and the guide explains how. Thanks
