Gunstar 2 is a four-barreled period 168 glider gun that uses four B-heptominoes moving around a period 840 track consisting of four 64-generation turns and eight 73-generation turns. The B-heptominoes make use of Buckingham's transparent block reaction. It was built by David Buckingham sometime before November 20, 1991.[1] It is quite a bit smaller than the standard gunstars and has a period that is not attainable by the standard method of gunstar construction.
