A simple, yet effective upgrade for the Umarex VFC GLOCK series of magazines.
The Nine Ball Gas Route Seal Bucking/Gasket improves upon the stock design by smoothing out the gas route channel for a more aerodynamic operation.
New cold-resistant material helps prevent freezing of the gasket, thus reducing possible gas leakage.
