m1a1 bolt handle

thingiverse

This is a bolt handle for a Thompson m1a1. The original model was made by Darren S on GrabCAD. https://grabcad.com/library/thompson-bolt-handle I'm using it in an airsoft Thompson with a real deactivated bolt. The original handle fit, but was a little loose in the slot on the side of the receiver. I chose to reuse the metal knob and just 3d print the part that slid into the bolt. It screws together with a 20mm long m4 socket head cap screw. The Fusion 360 file is included. I also made a printable m1a1 bolt. https://www.thingiverse.com/thing:5174461 I also made an adapter to use a 1928 bolt. https://www.thingiverse.com/thing:5174463
