A period-16 glider gun is any true period 16 glider gun.

The first, and so far only, true period 16 glider gun was discovered by Period1GliderGun on February 29, 2024. It is based on Charity's p16 and a period-16 B-heptomino hassler by Nora Brown. It is the first true-period glider gun with a period below 20 to be found.

This gun briefly held the record for the lowest-true-period gun known, until it was surpassed by the first known period-15 glider gun a few hours later.
