[Problems of hop-up system ]
If you adjust the hop strongly, the resistance increases and the initial speed drops.

[Rather than pushing BB bullets, rolling and hop rotation.]
RYUSOKU Flat Hop-Up Bucking rolls the BB on the face, not the point, so this can rotate it strongly even if there is little drop in the initial velocity.


  • " RYUSOKU " is the Airsoft tuning method born in Japan. RYUSOKU realizes strong hop rotation without dropping the initial speed even when heavy bullets are used, extending the flight distance.
  • Package Includes : Hopup Bucking, Hopup Nub
  • Hard is recommended for BB of 0.25 g or more, soft is recommended for BB less than 0.20 g
