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. It was built by David Buckingham sometime before November 20, 1991. It is quite a bit smaller than the standard gunstars and has a period that is not attainably by the standard method of gunstar construction.
