Marlin XT-22 single shot adapter

thingiverse

This is a single shot adapter for Marlin XT-22 bolt-action .22LR firearms. It replaces the factory magazine and allows the user to load rounds manually. An M2 socket-head cap screw is used to engage the magazine latch but any screw with a head diameter of ~3.5mm should work. It may be a tight fit so some post-processing may be required to smoothly insert/remove the adapter due to differences in printer tolerances. Updated 2019-09-15 to include a flush mount single shot adapter. Extra steps to sand down the rear flat surface should be taken to remove the layer lines which will make insertion and removal smoother. This model was inspired by and feed ramp dimensions came from this forum post: https://forum.guns.ru/forummessage/56/1152967-28.html
