Mid-Cap 120 BB Magazines for M4/M16 Replicas - black

The STANAG-style mid-cap magazine by Specna Arms is built for performance, reliability, and broad compatibility with most AR15-style AEGs, including M4, MK18, and M16 platforms. Its robust polymer body combines low weight with excellent field durability.

Equipped with a reinforced spring, this magazine handles heavier BBs (0.30g+) with ease, making it ideal for high-speed or high-power airsoft setups. With a 140-round capacity, it strikes the perfect balance between realism and functionality—without the need to wind it like a hi-cap.

Its realistic STANAG look and dimensions ensure it fits seamlessly into standard AR15 pouches—no custom gear required. The magazine's design mimics its real steel counterpart, enhancing both the look and ergonomics of your loadout.

Specna Arms has focused on universal compatibility, meaning this mag works smoothly not only in Specna Arms replicas but also with AEGs from other major brands. Expect consistent feeding, even with setups running at 20+ BBs per second.
