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

Magazine capacity [pcs]
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.
The gun is well made, metal slide, polymer frame. No real markings on the slide or frame, only the KWC logo. It came with a magazine and 2 additional backstraps for the grip. The overall build quality is good, not mind blowing. The slide wobbles a little, the wasn't any lubrication inside. The magazine came without the screw that secures de CO2 capsule. I called their call center and they sent me the missing part. 5 stars for that, they were really helpful. The recoil is ok, I managed to empty 2 magazines ( 30 bbs ) with 1 CO2 capsule. For the price paid the gun is ok. Kudos again to the technical team for sending me the missing part. You rock guys.
