Umarex Canada

Power & Ammo

Most Umarex CO₂ guns run on standard 12g cartridges, while select platforms may use larger cylinders or alternate gas systems.

Stock up on CO₂ / green gas so you’re not stuck mid-session, and choose ammo that matches your model’s specifications.

• CO₂: great for crisp cycling and consistent trigger feel; keep cartridges at a moderate temperature for best results.
