ALIAS GEM Single Shot Dual Calibre (4.5mm & 6mm) CO2 Pistol

The Smallest CO2 Pistol in the World

The ALIAS GEM is a micro-sized, single-shot, multi-calibre CO2 pistol that pushes the boundaries of compact firepower. Measuring just 92mm in both length and height, the GEM is among the smallest CO2-powered airsoft and airgun pistols on the market. With interchangeable barrels, it can fire 6mm airsoft BBs (ORANGE TIP ON 6mm BARREL), 4.5mm steel BBs and even .50 calibre paintballs (with additional accessories).

Designed for 8g CO2 cartridges, the GEM also supports standard 12g cartridges with the addition of a 12g CO2 adapter (sold separately).

A Familiar Concept, Reinvented

If you were active in airsoft during the 2010s, you might recall the Goblin Deuce/Solo—compact, multi-munition pistols that were legal for airsoft sites. The GEM comes from the same designers but with one key difference: instead of plastic, this version is solid metal, making it far more durable and robust.

A Unique Classification

Despite its ability to fire both Airsoft and Airgun projects, the GEM is legally classified as an airsoft gun. When shooting 6mm 0.2g BBs, it remains under the 1.5 Joule power limit, making it suitable for skirmishing. 

With both 6mm and 4.5mm barrels included, it’s entirely up to you how you use this little beast.
