For those who cringe at Nerf Guns being converted into airsoft guns, better look the other way, and for those who like to see how airsoft gunsmiths can work their magic can read on. Another Nerf Gun, this time a Vulcan, gets the PolarStar treatment as the Fusion Engine is dropped into it... "The conversion of the Vulcan was similar to the Nerf Stampede, but the box mag was located outside of the gun in the stock Nerf box mag, providing the capacity for 4000 rounds. The same technique was used --- gut the Nerf gun and mount the PolarStar Fusion Engine. Lathe down plastic rods to work as spacers for the inner barrel and bracket for the M4 hopup, then integrate the box mag mechanism with a long feed tube spring"
