Madbull Ultimate Ball Bearing Spring Guide Ver. III

The version 3 ball bearing spring guide features a slightly thinner diameter shaft to accommodate springs of all sorts, making it more forgiving for both the spring and piston to compress.

The spring guide's shaft is built-in with the top bearing plate to allow more rigidity and maximum spring decompression. As a spring decompresses, the bearings allow full rotational twisting of the guide shaft adding improved rounds-per-second and maximum power by allowing rotational torque in the spring not to build up.

The guide itself is CNC Aluminium with a smooth anodized finish making it tough, lightweight and low friction.

This model is designed for use in AEG version 3 gearboxes.
