ArcFlash Labs has come out with a new coil gun design that takes the best elements of their underpowered EMG-01 and their overly bulky GR-1 Anvil and melded them into a much handier EMG-02. This new design maintains the same muzzle velocity as the Anvil (200-250 fps / 60-75 m/s) but uses smaller projectiles (5/16″ armatures). It is far better handling, with the balance much improved by having a single large capacitor mounted at the rear and a battery directly under the grip. That battery is also now a commercial off-the-shelf rechargeable lithium-ion type.
It’s quite a lot of fun to shoot, and I am excited to see where this technology continues to develop!
