I recently bought a used DM14 and when it finally arrived, even though the outside was clean, I started looking at the lpr and hpr and saw some grit and grime stuck in the screws so I decided to tear them both down, clean and lube them up and replaced the reg seat in the hyper4.
First, is it normal for air to leak out the bottom of the Hyper4 reg as you make adjustments to itwhen first putting in a brand new seat? It did leak as I turned the reg out slowly and I kept dry firing in between and that would seal it up it seemed like.
Second, if I have access at home to only a chrono, is there a process I can follow to set my hpr and my lpr to proper settings? I don't have a gauge to use for testing the hpr pressure.
Thanks, Im trying to the gun working smoothly after it arrived in extra-used condition.
