I purchased new a FX Impact M3 in Fall of 2021. Model is 25cal with 600mm barrel. The first regulator was originally set at 150 to 155, but after 8 months began to fluctuate from 130 to 170. The standard deviation went from 8 to 10 fps to 30 to 40fps. The rifle looks like new and kept in the case in perfect conditions. I have only shot 3 or 4 tins. After sending back to dealer , I have been told both regulators were replaced and also the first regulator guage replaced as well. The first regulator was now however set wide open, so it mirrors the tank guage pressure. This was recommended to avoid the many problems associated with this gun's 2 regulator system. The second regulator is set at approximately 115. Has any one else had this issue and was the solution to open up the first regulator and shoot and operate the Impact M3 in this manner?
