MAGAZINE FOR HFC / KWA M11A1 & T77 Gas Sub-machine Airsoft gun
(NOT FOR KWA NS2 M11)

"Bought three of these guys for my HFC M11A1, they work as they should. No leaks and very good gas efficiency. I can get 2 magazines' worth of BBs before the gas gives out.

"They work well, the most I've ever gotten was 2 and a 1/2 mags, but thats in 5° weather, so gas efficency is actually some of the best I've seen. Only downside is the valves leak a lot, so I would recommend spending a few more dollars and buying a new valve with it, just in case. 8/10 (Would be 10/10 if it weren't for the leaking issue).

"Decent quality mags. Holds enough gas for about 1 mag in warm weather, but its gonna be a bit rough in colder climates (About half a mag in the winter).

Only complaint is that they easily get dirty and jam, since the portion holding the BBs are exposed to the dusty air during operation since its effectively an extended mag. Just a side effect of the design of the MAC-11.
