The day has finally arrived – it’s time to live fire test my 3D printed gun, the FGC-9 MK2.

AG Cast also let me know he isn’t positive it is a bad disconnector spring, since it could be a freak issue due to the heat I was experiencing. Here is a relevant link: https://www.ar15.com/forums/ar-15/New_lower_build__disconnector_problem/118-711851/

My FGC-9 was made with PolyMax PLA, though as I say in this video, I suggest thinner parts that have high spring pressure be printed in a higher temp material when living in hot climates.
