Vortex Viper PST Riflescope Availability We just received the following e-mail from Vortex We have some good news. Over the next few weeks we will be getting a very large amount of Viper PST riflescopes. It’s not enough to cover all the backorders but it will make a large dent in the amount of backorders you will be able to fulfill for your customers. We will keep you posted as those come in and provide you numbers we can ship you. Thanks for you and your customers continued patience on the PST series.
