this is a TMC adapter that works with the SAR12 marker. it also got the anti ball drop build in. so when you shoot your mag empty it will not drop te 2 last rounds that could not be fed in the chamber by the magazine
and yes I have not printed this thing out. but I did made a test fit of the part to make sure the mag adapter locks in place. and the magwel designs it self are tested. the only thing that I see could be a thing is that the mag should be just a little bit higher or lower. for feeding the rounds with out any problems.
to complete the adapter do you need 2 pins, and 1 spring
Link to video: about the Dmag/TMC mag adapter. the TMC and T15 adapter looks very similar in design
