From Double Eagle we have the Mid Cap Magazine for the M923A.
The Magazine
This is a uniquely shaped M4/M16 magazine. It has a 130 round capacity and is constructed from metal with polymer internals. It is loaded via speedloader through the top of the magazine.
Compatibility
This magazine is designed for the Double Eagle M923A but where it is based on a standard M4/M16 magazine, it is likely to be compatible with a range of M4/M16 replicas but we have not confirmed any compatibility.
