CETME charging tube straightener/mandrel
Description
This is for straightening out a CETME or HK91 charging tube which often get bent when taking out of the cut receiver. Just insert this thing into whats left of the hole, put the square end in a bench vise, and use a small hammer or tap hammer, hitting it up and down the length of the bent area while rotating the tube the whole time. Should take a few minutes but it will straighten out the charging tube no matter how hopeless it looks. I printed mine w/ 4 walls and 40% infill but im sure other settings will work too.
