HFC Gas Fill Valve for HG-199 M9 Green Gas Magazine, Silver

If your HFC HG-199 M9 magazine is losing gas pressure between fills, the fill valve is usually where the leak starts. This is the metal port you press the gas adapter into when refilling. Over time, the seal wears or the threads strip, and you end up with a magazine that won't hold pressure.

What gets replaced. This is the fill valve itself — the small metal component that screws into the magazine body. When it's seated correctly with a fresh seal, your magazine holds gas the way it did when new. No more wasted fills, no more magazines that go dead halfway through a game.

Fit and finish. Silver metal construction that matches the HG-199 M9 magazine. It's a direct replacement for the original valve, so you're not modifying the magazine or dealing with adapters. Just swap out the old valve and you're good to go.

Before you buy. Make sure you have the HFC HG-199 M9 magazine. This valve won't fit other M9-pattern magazines from different manufacturers. If your magazine is damaged elsewhere or the body is cracked, a new valve won't fix it.
