A STANAG type magazine which is designed to fit any Airsoft AEG rifle which accepts this style of magazine, such as M4, L85, 416, SCAR-L and more.

This magazine is the perfect purchase for any Airsoft skirmisher due to its low price and high quality, with the added bonus that should you one day visit a low-cap only site it can be quickly changed to suit your needs.

Full description


The magazine is constructed with a realistic looking Alloy case, with durable Polymer internals. The magazine is of a mid-cap design and loaded from the top, meaning the BBs are released on a spring system, meaning no rattle or winding once the magazines are full preventing you from being heard during a Skirmish. This magazine is unique in the fact that the capacity can be switched between 30 and 140 rounds, making it great for Airsoft skirmishers who also attend mil-sim games by quickly switching to the lower capacity. 


  • Part of NUPROL's Essentials range
  • For STANAG accepting Airsoft AEG / HPA weapons
  • Flip switch for switching between 140rnd / 30rnd capacity
  • Realistic STANAG design - Issued around the world
  • No rattle and no winding
  • Compatible with M4, 416, SCAR-L and L85 AEGs
  • Not compatible with F2000 AEGs - They get stuck!

Got a Specna and a Pioneer Defender and it fits them both. Heard about some people having issues with certain magazines not fitting, but never had a problem with this.
