I’ve been working on printing up a Nylaug, but my KAK barrel doesnt fit through the front hole, measuring the step file, it’s 22.86mm. Unfortunately I didn’t catch the dimensions of my barrel because I didn’t have my good caliper with me, but from the minimum specs image, the largest diameter on the barrel is 0.960 inches, or 24.38mm. Has anyone else who built a Nylaug had to open up the receiver channel more after printing? is my KAK barrel just out of spec?


The threaded rods are standard M3x0.5 like the original build documentation states. I can also confirm as I recently upgraded my 300blk out build not long ago. They tried to make it as compatible with the original build as possible. An interference fit is a good fit lol
