Muzzle velocity [FPS]![]() 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 | 320 |

| Magazine capacity [pcs.] | 31 |
Hop-Up![]() 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). | Yes |
Blow Back![]() 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. | Yes |
