Air Arms EV2 Regulator Removal Tool

thingiverse

I had to remove my Air Arms EV2 mk4 regulator. This is a tool I made to do this without marking or damaging the regulator body or action. People who are looking to do this have a difficult task as the Air Arms factory overtighten the regulator and air cylinder to the action to remove movement in the barrel as the pressure changes. I got the cylinder off by clamping the cylinder in a work bench and twisting the block with a couple of pieces of wood for extra leverage. At this point the action will separate in two possible places depending on which joint is weaker: 1. The regulator will remain in the block 2. The regulator will remain on the cylinder. This tool solves option 1, however you could make something similar to option 2. I clamped this block over the regulator using m3 screws that go into the 3 holds on the regulator body, clamped the regulator block into a work bench and twisted the block with the wood levers I made. It's very simple when you have the right tools.
