M4 magazine ONE-MAG, 120 BB-s

ONE-MAG type magazine for airsoft electric guns. The polymer mid-cap magazine holds 120 BBs.

Specna Arms introduces the new ONE-MAG mid-cap magazine designed for AEG rifles like M4 / M16 / MK18 and other platforms based on the AR-15 family. The ONE-MAG is the successor to the S-MAG series, which had a narrower profile that caused wobble in some replicas like the Specna Arms HK416 One™. The ONE-MAG features reinforced ridges in the upper portion to securely lock into the magwell. It is a universal, durable and affordable magazine with excellent feeding reliability. The body is made of lightweight yet strong polymer with a textured surface for confident handling. In short, one mag for all AR-15s – ONE-MAG.

In short: one magazine for all AR-15 type weapons – ONE-MAG.
