This is a replica of the Pegasus gate from Stargate Atlantis. The Atlantis Gate was an upgrade on the SG-1 version. On the show its glyphs appeared digitally, as the crew dialed into a new location. The gate had been left unused for thousands of years after the Ancients fled to the Milky Way after losing their battle with the Wraith, but was revived by the Pegasus team.

The replica gate measures 9.25 inches (23.5 cm) across. It is made of polystone and comes with a separate display base that carries the Stargate Atlantis logo. Master Replicas has carefully reproduced every glyph on the gate, which was based on a digital model that was supplied by MGM.
