  • Just wondering, did you ever get it fixed? i have the same prob with my e90

  • Hey dude just got my Echo 1 p90, and im having a similar issue, when i fill the mag more than 75 rounds it does exactly what yours is then when its at about 55-65 rounds itwill start shooting normally, from my experience this is a compression problem between the cylinder head, air seal nozzle, and hop up chamber, either of them can cause problems. if you figure it out let me know please, i myself am going to do a complete take down to figure it out!

  • there might be an imperfection in your barrel

  • air compression problem. check to make sure your cylinder is sealed properly and make sure your piston head isnt cracked.
