Period-50 glider gun is an extensible true period-50 glider gun discovered by Dean Hickerson on October 13, 1996. It is based on a period-44 gun by David Buckingham and the p50 traffic jam oscillator to restore the blinker, as well as 2 copies of this mechanism to restore the blinker in the middle. It can be made to have more than one barrel.

In 2004, David Bell, produced a variant using only a single oscillator with a glider loop. It is possible to restore the blinker by using queen bee shuttles but that makes this gun pseudo. The true period would then be p150. With the discovery of 55P10 in 2018, the true period-50 gun was vastly reduced.

A period-50 oscillator, which is simpler than the gun, can be made with the 55P10 version in the gallery but with block eaters on both the top and bottom instead of converting an active region to a glider on the bottom. This pattern has a minimum population of 160 (compared to 177 for the gun), a bounding box of 56 × 31 (same as the gun), heat 74.4, and volatility 0.82. For both the 55P10 version of the gun and the oscillator, a column can be removed from the 55P10 on each side at the cost of 6 extra cells per side.
