From G&G we have a Mid-Cap Magazine for M4/M16.
The Magazine
This is a replica 5.56mm M4/M16 Magazine for AEGs. It has a 120 round capacity and features a ridged design for better grip alongside “G&G” raised mouldings which act as magazine guides and help stabilise the magazine in the mag well. The magazine is comprised of a moulded polymer casing with polymer internals. It is loaded via speed loader through the top of the magazine.
Compatibility
This magazine is designed for G&G’s M4/M16 Series of Replicas but it is also widely compatible with many different brands of M4/M16.
