I recently purchased a Viper action to campaign for the 2004 benchrest season. The Viper is the benchrest model of the range of actions made by Gerry Stiller in Texas USA. The Viper is an aluminium action with steel inserts in the Stolle Panda style, in fact the footprint is the same and it will slot straight into a Panda inletted stock. The receiver is hard anodised in back, and the bolt is spiral fluted and bead blasted. It has an integral scope dovetail. The thing that most attracted me to purchase a Viper was the drop port ejection. There is a cutout under the action under which you inlet a small funnel type aluminium block, and the fired cases just fall out the bottom of the action when the bolt is fully retracted. I understand that Stiller has patented this ejection idea. This surprises me a little since I seem to recall Denis Tobler making a drop port action for his rail gun back in the early ‘80s! This action is made with computer controlled machinery to close tolerances. The bottom of the action is intentionally left with light machining cuts to aid in bedding. The configuration of my action, left port, right bolt and drop port ejection is lightning fast to operate. So fast in fact, that I have had trouble getting ready to fire due to alignment problems with the bags, rather than actually cycling the action and removing the case and then reloading. The action comes complete with 1” rings and trigger guard. I will be fitting it to a McMillan edge stock and will be looking forward to shooting it.
