As for you M4, what brand is it?
Anyway Chrono'd = Used a Chronograph to see the speed of the projectile.
The thing with the g36 is that it has quite a few upgrades; Prec. barrel, Stronger spring, New cylinder, New nozzle, New gears and it runs on a higher voltage... all that makes quite an increase in preformace and accuracy.
