Metal spring guide EVO 3 - A1 - ASG

Upgraded spring guide for the EVO 3A1. This upgraded spring guide features a high-strength steel core, making it capable of handling any spring strength that could be installed into the EVO. The outer part of the guide rod has a freely rotating holster made of POM polymer, which protects the spring from unnecessary wear and heat generation while minimizing friction. In combination with a supported thrust bearing, this spring guide can handle any force of the installed springs and ensure maximum spring life. It is also the simplest upgrade ever, as the spring guide on the EVO can be removed without disassembly.

Function:

• Extends spring life.
• Extremely strong, handles springs from M90 to M190 and above
• Increases ROF (Rate of Fire)
