It is the spped of bb, while its leaving the innerbarrel of replica. This speed is measured in FPS (Feet Per Second).
1 FPS = 0,3 m/s
1 J = 99 m/s
1 J = 326,7 FPS

Hop-Up system is used for overclocking bb during the shot (putting it in rotation), through which, it extends its flight path. Acting laws of physics make that bb lift up, while the gravitational force take it down. Appropriate adjustment of Hop-Up, will compensate for these two factors, which result in long and straight flight for longer distance and be greater focus shot (to improve accuracy).
Blow back is a simulation system of the cocking lever - it imitates the
work of it as the equivalent sharp. This system raises the realism and
adds a lot more experience during shooting.
Really good looking pistol, but as it was meant to be working with CO2 (which is compatible with - red nozzle) it has a really small gas magazine and really low gas efficiency (less than a magazine with a full gas charge). Mine came with a gas licking problem but now waiting for a replace thanks to the good customer support from gunfire. Really nice gun with best finishes but not really recommended for use in battles if you don't want to carry 2 gas bottles with you.
