These all new polymer magazines by Airsoft Systems are completely redesigned from the outside and also improved on the inside. These Airsoft magazines will fit and feed in 99% of the existing M4/M16/AR15 AEG rand HPA replicas, and with minor mods will fit the reining 1% like the 416 models.
The external design is focused on ergonomics and giving you a secure grip under the most harsh conditions.
The magazine is build to be extremely strong and to keep feeding even after the most inappropriate abuse.
Airsoft Systems have chosen the 85 rounds option as it provides the least possible frictional restrictions.
The ASMAG has been tested in extremely fast rate of firing guns. It kept feeding flawlessly even with the heavy 0.43 Bbs at 50 rounds per second!
While focused in making the strongest and most reliable airsoft magazine in existence, they also managed to make it very cost-effective and attractive.
