Frequently Asked Questions
What gas does it use?
The Echo1 GBB Cyclops SIL (JP-137) Pistol runs on green gas loaded into its gas magazine. Keep the magazine seals lightly lubricated with silicone oil, and store magazines with a small amount of gas in them to keep the seals seated.
What is the FPS?
Approximately about 330 FPS with 0.20g BBs as specified for this model. Actual readings vary with temperature, gas pressure or battery charge, BB weight, and hop-up setting, so always confirm against your field’s chrono limits before a game.
Is it full metal?
Yes — the main external construction is full metal, which gives it a solid, realistic weight. Metal parts still need normal care: keep moving surfaces clean and lightly lubricated.
What BBs does it use?
Standard 6mm airsoft BBs. Use 0.20g BBs for chrono and general play; 0.25g BBs fly steadier outdoors. Choose polished, seamless BBs to protect the inner barrel and hop-up, and never reuse fired BBs.
