Our take: Looking for a high quality all metal Mid Cap magazine for your M14, we've got just the mag. The all-new DBoys 150-round M14 mid-cap can be used with almost all metal gearbox M14 AEGs. Compatible with DBoys, AGM, CYMA, Echo 1, and TM M14 AEGs.
Great for MilSim (military simulation) scenarios that do not allow the use of hi-cap magazines, or if you simply don't like spending five minutes winding your mag during a game. Highly durable all metal build, and sleek flat black finish!
