Velocity drop

[93klauss]

WEll as title says having Fps drop off. Sometimes up 20 fps. Using Xvalve Lv X. Wondering if it could be the reg seat orings? Would that affect the FPS drop off?

Does your fps reset if you stop shooting for a few seconds. My wifes classic did that and I spent months replacing almost every part in it. Finally, I found a little piece of teflon tape stuck in where the elbow screwed into the valve. Took that out and the problem stopped. A very tiny obstruction in your airflow can cause this.
