This repair kit contains enough high quality replacement O-rings to replace all of the valve seals in eight Tokyo Marui M4 MWS magazines and convert them to silent fill, all packaged in a small plastic compartment box. Compartment box colour may vary between red or green depending on stock.
These kits are ideal for keeping in a kit bag or toolbox ready in-case you find a magazine has started leaking just before a skirmish or for fixing any existing leaks.
