I purchased a used L96 rifle Thursday. I was told the FPS would increase from 310-500 FPS if I were to remove the nozzle restrictor. I disassembled the gun...surprise surprise the nozzle restrictor has been removed or was never there. I haven't had it Chrono'd but I know it isn't anywhere near 500 FPS. This isn't much of a problem I plan to upgrade it anyway. Which is my first question, what upgrades will increase the FPS the most, as well as accuracy and range? Also, the rifle has no brand name on it that I could find. Is there some special way to tell? Cause without that I believe the upgrades will be very trial and error. Any help will be appreciated. Thanks
