Increase the power of your Marui 1911A1 Hi-Capa 5.1/FN5-7 by installing this high output valve. The ultra-wide opening allows more gas through per trigger pull to propel the BB at higher velocities out of your Marui pistol, and gives a crisp blowback experience.
The ball bearings included with the Nine Ball Hi-Flow Valve are to be placed inside the gas reservoir to promote more consistent high-power gas release. Just another innovation to ensure maximization of power whilst providing a deeply satisfying shooting experience.
