The bi-gun is a double-barreled glider gun that was found by Bill Gosper in the early 1970's.^[1] Much like his Gosper glider gun works by colliding two queen bee shuttles together, the bi-gun works by colliding two twin bees shuttles together. Dietrich Leithner discovered that it can be synthesised with 12 gliders.
