The KRYTAC Rotary Hop Up Assembly is constructed of high quality polymer and features many user friendly updates to traditional M4 hop up systems. The rotary adjustment wheel is precise and definitive, each click position is numbered and the hop up offers a tactile and audible feedback when adjusting. The lever arm can be lifted upwards to give access to the hop up nub chamber for easy adjusting or cleaning. Also, the hop up nub is retained by the arm to prevent loss when changing barrels or hop up buckings.

  • Rotary style adjustment knob
  • Tactile feedback adjustment
  • Easy maintenance

"Favorite hop unit. The dial clicks with adjustment so it won't move on it's own. Very nice.

"This is a great hop up all around. It is a little bit delicate & the plastic isn't the best quality, but it's still good.
