"The K3G4 is a 20 round assault rifle that possessed the capability of penetrating flak jackets. This gun was used in Syphon Filter, 2, and 3, and was classified as a assault rifle, even though it was fired one handed. The design is nearly identical of the PK-102 assault rifle from Syphon Filter and 2, but excluding the stock."@en . . "K3G4 Assault Rifle"@en . . . .
