Bearings G&G Bushing 8 mm

These G&G Bushing 8 mm bearings are made of metal and they can be used as spare bearings. If the gearbox in your airsoft replica still uses polymer bearings, then these G&G Bushing 8 mm bearings can even be considered a substantial upgrade. Metal bushing bearings last longer and they ensure the gears can keep spinning smoothly for longer. These metal bearings are also highly recommended if you’re running a high-performance airsoft replica build.
