Watch the result of putting a Krytac Hop-Up unit into the G&G FN2000 which what JedBedrock exactly did... "Hello everyone and welcome back to another airsoft video. In this video, I install a Krytac hop up into my G&G FN2000. The FN2000 uses a special hop up. I modified a Krytac hop up to fit into the gun. it now shoots on par with my Trident MKII."
