The EMG-01B is a small portable rail gun made by Arcflash Labs. Introduced in 2017, it can throw magnetic dowel pins approximately 1/4" x 3/4" (6mm x 19mm) at about 150 fps (45m/s). It does this with a series of 8 capacitors and electromagnetic coils, and holds 18 projectiles in its magazines. Generating just under 5J of energy per shot, the EMG-01 is similar to a BB gun, and it was this lack of power that led to development of the GR-1 Anvil.
