£199.95
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.

Important CO2 Usage Notice for the GEM
Do not store the pistol with a CO2 cartridge installed, especially when using the 12g CO2 adapter.
Leaving CO2 in the gun for extended periods may cause the internal O-ring in the CO2 cap to shift, which could result in gas venting.
If you experience venting, check that the rubber O-ring is correctly seated at the bottom of the threaded CO2 cap before continuing use.

Beautiful little pocket monster.
It is a micro masterpiece.
Beautiful in design and construction.
A real GEM of a fun gun
It will happily shoot good quality pellets apparently
And I see no reason why not.
Lead or green pellets are softer than steel BBS, and far less likely to cause wear on the smoothbore .177/4.50mm barrel.
One very vital add on, which the brill guys n gals at V-A have in stock...BE SURE TO BUY THE 12Gr CO2 EXTENSION UPGRADE. IT'S A BIT LONGER THAN STD ONE, BUT ESSENTIAL 🤠✝️💟
