The position of the right hand is more comfortable because the circumference of the grip is not so large. In addition, the grip is longer and thus also provides support for larger hands.
The buttstock is shorter, so the ratio of the grip length to the trigger is better. The wrist is centred on the axis of the trigger. Furthermore, the buttstock is more recessed in the chest area. The grip is strongly slanted to allow extreme stops.
In addition, the 8002 has a faster locktime due to the new trigger, the trigger weight can be set lower, it has a dry training unit and a Stabilsator.
