In 2010 we were contacted by Naval Surface Warfare Center in Crane Indiana. They asked if we were interested in bidding on the Mk13 Mod7 project to supply custom actions for the Mod 7 version of the Mk13 300 WinMag sniper platform.
This was the first time they considered using a custom action for this platform. We decided to compete and ultimately won the very difficult competition. We supplied five of our TAC 300 actions pulled at random from our inventory. What the Navy determined was that the Stiller Actions offered 100% parts interchangeability.
For the first time in the history of the Mk13, any part from any Stiller based rifle could be interchanged with the same part on a different rifle with no change in function or accuracy. We have since developed a special QC process to which every Mk13 action is subjected. In addition, all the internal parts are black iron nitrided. Occasionally, we have a few extra actions that can be offered to the public.
