JBU Version 2 Ball Bearing Spring Guide

JBU Version 2 Ball Bearing Metal Spring Guide

The JBU Ball Bearing Metal Spring guide is a great upgrade for AEGs that use Version 2 Gearbox. The spring guide will greatly increase the longevity of your compression system due to its metal construction and ball bearings. The ball bearings allow the spring guide and spring to freely rotate while in motion relieving stress on both the spring, cylinder and gearbox.
