The Madbull Airsoft Ultimate Version 2 Ball Bearing Spring Guide is a light weight aluminum guide and uses a bearing rotation plate on the bottom of the guide to allow the spring to rotate freely during compression and decompression, which reduces stress on the spring and extends the service life of the spring. The shaft of the guide is thinner to accommodate a wider variety of springs than a regular spring guide.

This spring guide is made to fit Version 2 type gearboxes, commonly found in M4 platform rifles, and MAY fit in other version 2 gearboxes, but cannot be confirmed by AirsoftGI
