Period-184 glider gun is a true period 184 double-barrelled glider gun found by Dave Buckingham in July 1996. The engine in this gun is a Herschel descendant. Unlike previously discovered glider guns, the reaction flips on a diagonal so that both gliders travel in the same direction. This is the fourth smallest gun, after the Period-156 glider gun, Gosper glider gun and Simkin glider gun, and is the highest-period among them.
On June 11, 2019, Jeremy Tan found a 15-glider synthesis for this gun.
