AirsoftPro reinforced magazine spring is a replacement upgrade spring designed for most airsoft real-cap and mid-cap magazines with a round spring profile. Thanks to its thicker spring wire, it provides faster and more reliable BB feeding, making it ideal for high rate-of-fire builds or when using heavier BBs.

For more than 25 years, we know what you like about airsoft.
This reinforced spring is manufactured from high-quality DIN 17223/C spring steel wire with proper heat treatment. Compared to standard magazine springs, it uses thicker wire, providing greater spring tension and ensuring more reliable BB feeding into the feed channel. It is especially suitable for high rate-of-fire AEGs or when using heavier BBs, where the original spring may struggle to keep up. The increased spring force comes at the cost of a slightly reduced magazine capacity. For example, a standard 70-round mid-cap magazine will typically hold around 60 BBs after installing this spring.
The spring is made from wire with a 0.1 mm larger diameter than standard versions, providing increased spring tension.
Provides faster BB movement to the feed channel and helps prevent feeding issues in high rate-of-fire setups or when using heavier BBs.
Manufactured from DIN 17223/C spring steel wire with heat treatment for long service life and consistent mechanical properties.
Designed for real-cap and mid-cap magazines with a round-profile spring, regardless of manufacturer.
Suitable for high-performance AEG builds and for setups using heavier BBs where reliable feeding is essential.
