Marlin XT-22 single shot adapter

thingiverse

This is a custom designed adapter for use with Marlin XT-22 bolt-action .22LR firearms. It replaces the standard magazine, allowing users to load rounds manually. An M2 socket-head cap screw engages the magazine latch, but any screw with a 3.5mm head diameter will work. Insertion may be a tight fit due to printer tolerances, so some post-processing is recommended to ensure smooth insertion and removal. Updated designs now include a flush mount single shot adapter option. Extra steps should be taken to sand down the rear flat surface to remove layer lines, making insertion and removal even smoother. This design was inspired by and features feed ramp dimensions similar to those found in this online forum post: https://forum.guns.ru/forummessage/56/1152967-28.html
