ONE-MAG Magazine for M4 / AR15 by Specna Arms
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.
