Operation and practical use

The spring-fed mid-cap mechanism delivers BBs without requiring a winding wheel. Unlike conventional high-capacity magazines, this design also eliminates the characteristic rattling sound caused by loose BBs inside the magazine body.

The textured housing and flared floorplate make the magazines easier to handle during reloads, including when wearing tactical gloves. The translucent side windows allow users to check the position of the internal high-visibility follower.

Compatibility

Designed for Krytac M4 AEG rifles and other compatible M4/AR15 electric airsoft platforms using STANAG-pattern magazine wells.

Fitment with other manufacturers' AEGs should be checked for magazine catch engagement, dimensional tolerances and reliable BB feeding. These magazines are not intended for GBBR platforms requiring dedicated gas magazines.
