The bi-gun is a double-barreled glider gun that was found by Bill Gosper in the early 1970s.[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.
This gun appeared semi-naturally on February 12, 2022, in a symmetric soup submitted to Catagolue by Charity Engine.[2] This makes it the second unique gun to have occurred in a soup, after the period-156 glider gun.
