'''Gunstar 2''' is a four-barreled [[period]] 168 glider [[gun]] that uses four [[B-heptomino]]es 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, [[:Category:Patterns found in 1991|1991]].<ref>[[Alan Hensel]]'s [http://www.ibiblio.org/lifepatterns/ lifep.zip pattern collection].</ref> It is quite a bit smaller than the standard [[gunstar]]s and has a period that is not attainable by the standard method of gunstar construction.

Using different mechanisms, gunstar 2 is smaller than the forerunner [[gunstar]]s.
