Alright. I will do that next time I clean.
I did not touch the hop up, however I just got a bit of cloth and just slowly cleaned the barrel - I did not go full length, only half the gun and no dirt came out.
I just chrono'd it after cleaning. at 1J im hitting 292-296 fps and the fps when I started, I was actually hitting 298-300, Is that something gone wrong or is that normal?
