REAL GAS BLOWBACK TM M4A1 MWS STRIKE HOP ARM

Tokyo Marui GBB M4MWS is known for its stable accuracy, but with its original chamber hop arm, the Hop tends to be weak, and lacks performance for long distance shots.
  
We redesigned the shape of the arm, to get better and stronger Hop up compared to its original Hop arm.
 
It can also be adjusted to non-hop status, so it is compatible for both long and close distance.

Compatible Model:

• Tokyo Marui Gas blow Back M4 Series
• M4A1MWS
• CQBR
• M4A1 Carbine

Material: CNC Aluminum Alloy
