Halo 5 Guardians MA5D scaled to length as seen here. http://halo.wikia.com/wiki/MA5D_Individual_Combat_Weapon_System done by Pillar of GMod, converted and scaled by myself, OBJ and STL included feel free to edit. Model is not print friendly I believe in it's current state. I recommend printing the model made by this person. https://www.myminifactory.com/object/halo-5-assault-rifle-11734
