Well i got a Jg m4 s-system...... Had it for about 3 months now... How can I increase the range... I'm trying to turn it into a sniper... Are field limit is 450Fps for full auto.. anything over has to be single shot.. So Im looking for the fps of 425 or so. Right now my gun shoots about 375-385.. I wont like to have nice range.. "if that's even possible" I just got done messing around with it in my back yard... For some reason my .20s shoot better then my .25s.... So idk whats up with that but yea any suggestions would be appreciated... I'm trying to stay under 150$..
