APS 300rd U-Mag Hi-Cap Magazine
APS U-Mag sets a new standard for Hi-Cap magazines for M4 AEGs. By using Japanese quality components, APS has eliminated the need for constant winding during gameplay – one full wind is enough to fire all 300 BBs.
Store tip: This magazine is a game-changer for anyone who likes Hi-Cap capacity but hates having to turn the wheel every 30 shots. The quality of the Japanese spring is immediately noticeable in the feeding performance.
Built for tough use
APS U-Mag is made from high-strength POM polymer, a material known for its extreme durability and low friction. This makes the magazine highly resistant to impacts and drops in the heat of battle, while the internal parts move smoothly. The injection-molded feed lip ensures that the magazine fits precisely in most M4 rifles on the market.
The biggest advantage, however, is the technology inside. The heat-treated spring from Japan retains its tension significantly better than standard magazines, giving you a tactical advantage by allowing you to empty the entire reservoir without interruption.
Don’t forget the essential accessories!
To ensure you get the best experience with your APS U-Mag, we recommend the following:
- Quality BBs: Always use 0.20g or 0.25g precision BBs to prevent jamming.
- Maintenance: A small drop of silicone oil in the feed channel helps maintain the seals and spring.
- Magazine pouches: Check out our selection of Molle pouches for quick magazine changes.
