● Achieve powerful hop for long-range shooting!  
● Delivers stronger hop-up performance than the standard model!  
● Made from high-strength aluminum alloy with precision machining, specially designed for the Gas Blowback M4 series!
 
The Tokyo Marui M4 MWS boasts impressive accuracy, comparable to electric guns. However, in its stock form, the hop-up adjustment is limited, making it less suitable for long-range shooting. To address this, we redesigned the Strike Hop Arm for Tokyo Marui M4 MWS, adopting a structure that directly presses the packing. This enables a stronger hop-up effect than the original!  
 
You can also set the hop-up to the "off" position, allowing you to adjust for various shooting distances!  
Compatible Models from the Tokyo Marui Gas Blowback M4 Series: M4A1 MWS, CQBR, M4A1 Carbine
