GSG Drum Adapter for Derya TM22

This adapter will connect a GSG 15/16 drum to a Derya TM22 10 round magazine, and will allow the 22LR drum to function normally on your TM22! It’s made out of a durable wear-resistant engineering resin and is sanded and painted for a smooth finish. All required hardware is included, but the drum and magazine are not. The fitment is different between the metal and polymer magazines so please pick the correct one. As with all of my products these are made to order so please allow about a week for manufacturing before it ships.

To install, remove all of the internal components of the TM22 magazine as well as the top part of the GSG drum. Fill the drum with the provided 23 dummy rounds then attach the magazine to the drum using the adapter. The drum can now be filled via the magazine and will operate at the original intended capacity. Please note that the first few rounds can be tricky to load as the dummy rounds make it from the adapter to the drum, but once the dummy rounds are in the drum it should load and feed smoothly. The rounds feed into the drum “rim side” down so if you have any trouble getting them in just push down on the rim side and it should go in just fine. The rounds need to enter the magazine nose up, so it’s normal for them to fan out in the middle while feeding.

Note that this ad is for the adapter ONLY, and that the drum and magazine required are NOT included.
