M4/M16 | 5-Pack | Mid-Cap | 140rds | AEG | Magazine | Specna Arms

This is a set of five mid-cap magazines by Specna Arms, specifically designed for AEG replicas of the M4/M16 type with STANAG compatibility. Each magazine offers a capacity of 140 BBs and is constructed from durable polymer in a sleek black finish. The 5-pack forms a complete loadout expansion for players who want to carry more magazines into the field without needing to reload constantly.

Technical specifications and compatibility

The magazine is made from polymer, ensuring low weight and good wear resistance. The platform is M4 / AR15 with a universal fit on STANAG-compatible replicas. The power source is AEG, meaning this magazine works with the standard spring pressure of an electric airsoft replica. With a capacity of 140 BBs, this magazine falls within the mid-cap category. The key practical advantage: BBs remain silent inside the magazine during movement, unlike hi-caps where BBs rattle audibly while walking or running. This makes the magazine more suitable for situations where noise discipline matters.

Practical use

The fastest way to load this magazine is with a BB speedloader via the top feed opening. The spring inside the magazine then automatically pushes the BBs upward towards the hop-up unit of your AEG. As this is a mid-cap, there is no wheel to wind as with a hi-cap. Once empty, you immediately need a fresh magazine, which makes handling more realistic and trains magazine changes. The 5-pack fully fills a standard chest rig or plate carrier fitted with M4 magazine pouches.

Who is this magazine suitable for?

This AEG magazine is intended for players with an M4 or M16 replica who value silent operation and realistic magazine management over maximum capacity. It is well suited to milsim participants, tactically minded players, and anyone looking to expand their loadout in one go with multiple airsoft magazines. The polymer construction keeps the overall weight low, which is convenient during longer game days with a full kit.
