New gun 2 is a glider gun that consists of a period 144 block factory whose output is converted into gliders by the no-longer-unnamed period 72 oscillator "two blockers hassling R-pentomino". It is David Bell's improvement of a gun that Bill Gosper found in July 1994. The period 72 oscillator is by Robert Wainwright, 1990, and the block factory is Achim's p144 minus one of its stabilizing blocks.
