Tokyo Marui EVOLT Custom Hop-Up Arm for M4A1 Carbine "CNC Hop-Up Arm EVOLT AR15"
The genuine one has a two-pronged arm that presses the hop-up pad directly, but
By using this hop arm, you can use the conventional Tokyo Marui cushion rubber (Φ3mm x width 3.5mm standard) for electric guns.
Depending on your ingenuity, you can use a variety of cushion rubbers of the same standard, greatly expanding the scope of customization.
When assembling, please apply oil to the pin holes as they are tight.
*Note*
Cushion rubber is not included. Please prepare it separately.
