Hello, this is my SPR/Severe-Duty based muzzle device for airsoft VSR - the thread is M20x1 and its for the long outer barrel - diameter at the end of the barrel is 23,4mm
Print it with support with the front of the muzzle brake facing the bed. I printed mine at 0,2mm layer height but lower is better. 2 walls at 0,67mm and 25% infill is what I used.
