The WE Tech M9/M92 Gas Blowback (GBB) Drum Magazine is a high-capacity airsoft magazine designed to provide extended firepower for WE M9/M92 series pistols.
 
Product Details & Features
Capacity: The magazine typically holds around 350 to 400 rounds of 6mm BBs, significantly more than standard or extended stick magazines.
Power Source: It is designed to run on standard airsoft green gas, with an integrated, large gas reservoir. The fill valve is on the bottom, and it is also easily convertible to HPA (High Pressure Air) systems for consistent performance.
Construction: The drum features a combination of full metal and high-density polymer construction, offering durability with a realistic weight. The magazine stem is made of metal to minimize the risk of damage.
Feeding Mechanism: It uses a manual winding wheel system on the front to ensure smooth and consistent BB feeding into the pistol.
Aesthetics: The drum is often available in an Olive Drab (OD) or black/red finish, adding a distinct look to your loadout.
Compatibility: While designed primarily for WE M9/M92 GBB pistols (including the M92F and M92A1 models), it is also noted by some sources to be compatible with other Tokyo Marui or KJ Works M9/M92 compatible models, possibly with slight modifications.
