Airsoft Atlanta does a test fire of a prototype version of the upcoming Wolverine Airsoft Bolt... "Airsoft Atlanta has a prototype of the Wolverine BOLT HPA system for the VSR-10 series of airsoft guns. Fully adjust its FPS with a regulator! The BOLT is an amazing HPA kit that works on most VSR airsoft sniper rifles. Some light customization and tool work is needed for installation (simple drilling of the rifle). Wolverine will have a detailed installation video online soon."
