Stiller Actions are designed for hunting use, but they can also be used for competition.

They are 416R stainless steel actions with a Remington 700 style footprint. It is available in both single shot and repeater versions in both right and left-handed variants. Short actions have 223, 308 and magnum bolt faces, long actions have 308 or magnum bolt faces. The Predator has a number of features that factory actions lack. It has an extended magazine well for the handloader who likes to seat his bullets longer than factory ammo. It uses the most dependable extractor available today and has an enlarged primary extraction camming surface. It uses #6 screws for scope base mounting. The bolt is one piece, hand lapped to the action and fluted for better function in the field. The firing pin is fluted for faster lock time and is fully supported within the bolt body. The bolt handle is threaded for the bolt knob of choice.
