Description
The Umarex 23rd S&W M&P 9 Green Gas spare airsoft magazine by VFC is made from heavyweight aluminum, giving a hefty feel to the M&P 9 airsoft pistol. This green gas Umarex magazine has a high-efficiency internal gas system providing excellent FPS output, and reinforced valves and seals for optimal gas retention. We recommend using Valken Green Gas with this gas pistol magazine.
