GunsModify have released photos showing a magazine lip and bolt stop level for TM / GM MWS magazines which also hints that they will be releasing a complete magazine of their own shortly.
These new parts are stronger and less likely to break if dropped on the floor, the general design has also been changed to help reduce nozzle failure and jams.
UPDATE 06/04/21: Here’s some more photos of their kit and new magazine they are working on; it takes 34/35 BBs.
