HFC T77 Full Metal Green Gas SMG – Full Auto
Bring compact gas-blowback performance to your CQB loadout with the HFC T77 Full Metal Green Gas SMG. Built around a compact submachine-gun platform, the T77 combines green gas operation with realistic blowback action, selectable semi-automatic and full-automatic fire, a folding stock, and a 40-round gas magazine.
With a listed velocity of approximately 300 FPS with 0.20g BBs, the HFC T77 is designed around maneuverability and rapid engagement rather than the long overall length of a traditional airsoft rifle. Its compact profile makes it especially well suited to CQB environments, indoor arenas and players who enjoy classic gas-powered SMG platforms.
Overview
The HFC T77 is a green gas powered gas blowback airsoft SMG featuring Safe, Semi-Auto and Full-Auto fire modes. Each shot cycles the blowback system to provide mechanical movement and a more engaging shooting experience than a non-blowback gas platform.
HFC equips the T77 with a folding metal stock that allows the platform to transition between a highly compact configuration and a more stable shouldered setup. This versatility makes the T77 useful in tight indoor spaces where maneuverability matters while still giving the player additional support when desired.
The included 40-round HFC gas magazine serves as both the BB feeding system and gas reservoir. The replacement magazine is identified by model number HGG-203M, making it easier for players to identify the correct spare magazine for the platform.

Field Tips
- Chronograph the T77 using the BB weight and gas you intend to use before entering the field because gas-powered airsoft guns can vary in output with gas type and temperature.
- Keep the gas magazine seals properly maintained with airsoft-safe silicone lubricant according to the manufacturer's maintenance recommendations.
- Avoid storing the magazine in extremely hot environments or direct sunlight.
- Use high-quality seamless 6mm airsoft BBs to help maintain reliable feeding.
- Full-auto operation consumes gas considerably faster than controlled semi-automatic fire, so additional magazines can be useful for longer games.
- Always follow the velocity, full-auto and minimum-engagement-distance rules established by your local airsoft field.
