Airsoft Evolution Anti-Freeze Mag Base Seal For VFC AR / M4 Standard GBB Magazine

Eliminate bottom-plate gas leaks and improve your magazine's cold-weather endurance with the Airsoft Evolution Anti-Freeze Magazine Base Seal. Designed specifically for the standard VFC AR / M4 GBBR magazines, this heavy-duty base seal is a must-have upgrade for maintaining a perfect airtight system.

Gas blowback magazines are prone to severe temperature drops during rapid firing. Standard factory base seals often freeze, shrink, and crack under these conditions, leading to massive gas leaks from the bottom of the magazine. To combat this, Airsoft Evolution has engineered this seal using a proprietary anti-freeze reinforced synthetic rubber. This advanced material remains highly flexible and structurally intact even under extreme cold and high gas pressure, ensuring your magazine stays sealed and ready for action.

(Please note: This product is designed for standard VFC AR/M4 magazines and is NOT compatible with VFC V-MAGs.)

Key Features:

• Anti-Freeze Material: Specially formulated synthetic rubber resists shrinking, hardening, and cracking during rapid gas discharge and cooldown.
• Reinforced Durability: Highly resistant to tearing and high-pressure blowouts, significantly extending the lifespan of your magazine seal.
• Cure for Base Leaks: The perfect solution for fixing or preventing the common bottom-plate gas leaks in VFC standard magazines.
