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

During rapid fire, gas blowback magazines experience a drastic drop in temperature. Standard factory seals can harden, shrink, and ultimately fail under these freezing conditions, leading to frustrating gas leaks. This Airsoft Evolution seal is manufactured from a specialized, temperature-resistant compound that remains pliable and maintains a perfect airtight seal, even when subjected to extreme cold and rapid gas expansion.

Whether you play in colder climates or have a heavy trigger finger, this anti-freeze seal ensures your gas stays exactly where it belongs—inside your magazine.

Key Features:

• Anti-Freeze Technology: Specially formulated material resists hardening and shrinking when exposed to freezing temperatures caused by rapid gas discharge.
• Ultimate Leak Prevention: Creates a superior, long-lasting airtight seal at the base of your magazine valve.
• All-Weather Reliability: Keeps your magazines performing consistently in both cold and warm environments.
• Direct Replacement: drop-in fit on factory VFC magazines.
