ASG Scorpion EVO 3 A1 Bearing Steel Spring Guide

About the ASG Scorpion EVO 3 A1 Bearing Steel Spring Guide

This is a replacement/upgraded spring guide from Action Sport Games for the Scorpion EVO A3 family of AEGs. All current production EVOs come out of the factory with this machined spring guide. Earlier models had a cast spring guide which could potentially fail if the spring was upgraded beyond stock to a much higher FPS. ASG has addressed this and now offers this CNCed piece which is much more durable than ever before. If your factory spring guide in your EVO does not look like this one, you have the older version.

The spring guide is a component found in an Automatic Electric Gun (AEG) gearbox (also known as mechbox). Electric airsoft guns function like spring-powered guns internally, where you have a piston forcing air through a cylinder and out of the gearbox to drive the BB out of the gun. The piston needs to be pulled back, cocked, and released on the trigger pull. The difference between a simple spring-powered gun and an AEG is that an AEG does what the spring-powered gun does but without having to be manually cocked, and it can do it in semi or full auto by using a gear and motor system to do all the work. Behind the piston is a powerful spring that dictates how hard the gun is going to shoot. Players can upgrade or downgrade their AEGs by swapping springs to adjust the velocity that their guns will shoot. Holding the spring in place is the spring guide, which keeps the spring from popping out of place during compression and causing jams within the gearbox.

Standard spring guides will typically be plastic or cast metal from the factory. Spring guides are not known to break but it is not in the realm of impossibility. Spring guides can be upgraded to improved designs such as ones that have bearings. The bearings increase the life of your spring by preventing the spring from binding. The bearings do this by providing some give for the spring as the coils may want to naturally turn and rotate when under tension. One byproduct of running an aftermarket spring guide is that sometimes these bearings increase the tension of the spring and can increase velocity a tiny bit. The space occupied by the bearings will pre-compress the spring.

If you need gearbox work done please consult with someone experienced in the matter. Gearbox work is very tricky and we can guarantee you it will not go as planned on the first try. If you are looking into learning to tech though, there is a wealth of resources online with many video guides from the community on how to work on an airsoft gun. We recommend not messing with your good working gun and instead purchase a second gun and try to learn on that. We would recommend learning on the M4 platform since the M4 with version 2 gearbox is the most prominent design out there and you can problem solve and get parts for them pretty easily.
