A period-435 glider gun is any glider gun emitting a glider stream with period 435. A true period 435 double-barrelled glider gun was constructed by Scot Ellison on 5 December 2003, shown in the Karel's p15 and heavyweight volcano articles. The original version used David Eppstein's first discovered larger variant of the heavyweight volcano.

Smaller period-435 guns have since been constructed.

Below is shown current smallest known period-435 glider gun by bounding box (55 × 62), using the 84P87. The hassling oscillator from the period-87 glider gun that creates the glider is replaced with a lower-population variant that uses one more row, because the bounding box is extended by the quinti-Snark anyway
