FX Impact Tungsten Hammer FX20710
This tungsten hammer for the FX Impact replaces the original hammer. An upgrade that causes the valve to be opened for a longer period of time, which releases more pressurized air to thrust the slug/pellet out of the barrel.
This is possible because of the material density of tungsten, which is 1.7x that of steel. This increase in weight causes the longer valve release. A great improvement, very much suited for use with heavier slugs.
The Tunsten Hammer is compatible with the FX Impact MKI, MKII, M3 , M4
