Has anyone played around with replacing the gas jet screws to different sizes? I don't know what the factory gas jet size is for the FS2000, but the SCAR 16's is 1.35mm. I'm assuming the FS2000 is the same since they're both 5.56. I'm considering replacing it with a smaller size like 1.25mm. Just curious to see if anybody else did the same and what their results were.
