Does anyone know of an off the shelf way to use a tri lug adapter on the new FTN.5 Rifle cans? If not, is it as simple as modifying the thread adapter insert STL to take the threads of an off the shelf tri-lug adapter?
Never used CAD and this might be the project to get me to learn. I really want a white monster can hanging off the end of an MP5


i have been trying to design a 3 lug mount to work with the ftn5. if you still need somwone to test fit, let me know. got a handfull of form 1’s back and im ready to start building.
