  • Are Viper Taiwan still in business?

    Or are they out of business?

    Their wepbage is down now.

  • Holy lightweight carrier, Batman!

  • @FoxhoundTR That's not the wrong stock. It's an M-117 replica so it's supposed to have the smaller LE stock.

  • Can you make a longer vid on the Viper.

  • Only letdown are the f*d up markings and the wrong stock

  • Hey Ra-Tech is the recoil on the Viper GBBR's comparable to Inokatsu? If used with your super recoil kit will the recoil be even a little more when used with an Inokatsu or a Viper? That is what I wan't to know and will you guys get Viper's M16A1 GBBR because, I wan't to buy that one. Thanks.
