Yeah, when my black one arrived, it had a little rattle comming from the trigger bars. My green one didn't rattle at all, so it bugged me. On top of that, I knew exactly what was making the noise and how to fix it. (spread the bars apart just a little)
So... Away I went to "fix" my noisy FS2K. There are a lot of little springs, especially that one which holds the take-down catch that were pretty trickey to get back in place. I managed to fix my rattle and get everything back together and 100% functional. And now... no rattle. :wink:
My wife and I were nervous and hoping I wouldn't have to send it back to be reassembled. It was a good thing having another FS2K to go by as a guide for reassembly. The key thing to remember is do NOT force anything and TAKE YOUR TIME.
