Heckler & Koch USP spring-action pistol replica
The replica is made of plastic. The slide, which bears the markings of the real firearm, is made in the silver color. The replica is powered by a spring. This means that it needs to be reloaded before each shot. The anti-skid surface of the pistol grip prevents the sliding of the replica in the hand. The heavy as for a plastic made magazine holds 25 BB pellets. The trigger moves backwards after cocking the hammer thanks to what it iis possible to place a faster shot.
The set includes:

- a low-cap type magazine holding 25 BB pellets,
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).
