Thompson 1928 bolt adapter

thingiverse

This is an adapter to use a Thompson 1928 bolt in a m1a1. I'm using it in an airsoft aeg to make a dummy replica. I started with a 1928 bolt by MikeS on GrabCAD. I reworked it using dimensions from a real m1a1 bolt. I moved the charging handle hole to the slot for the blish lock so no modification to the bolt is needed. https://grabcad.com/library/thompson-1928a1-bolt Real m1a1 bolt are expensive and hard to find. Stripped 1928 bolts are still available. The slot for the blish lock is almost completely covered by the cocking handle. I also made a printable m1a1 bolt. https://www.thingiverse.com/thing:5174461 The airsoft cocking handle knob can be reused. https://www.thingiverse.com/thing:5172034 The Fusion 360 file is included.
