Green gas magazine for Army M1911 tactical R31 and R29 models and compatible with most other 1911 Airsoft pistols (APS, KJW, Tokyo Marui).

The magazine cannot be used for the R 26, 27, 28, 32 models, but with some filing work on the underside of the handle, the magazines can also be used for these models. See the picture for the correct location on where to file / grind.
