The Stiller TAC300 action serves as a core component for custom bolt action rifle builds, particularly aimed at those specializing in long-range precision shooting. With its origins rooted in skilled craftsmanship and technical expertise, Stiller has carved out a niche for meticulously creating reliable and precise rifle actions for tactical and hunting applications.
A common struggle for builders of custom rifles is finding an action that provides both high-grade strength and a firm foundation for accuracy. Variances in action quality can directly affect the performance, especially over long distances where precision is non-negotiable. The TAC300 action, built to withstand the demands of larger calibers suitable for long-range use, offers a solution in the form of a robust and finely tuned mechanism.
the TAC300 by Stiller is designed to provide a base for those intent on creating a rifle tailored to their precise specifications. It bears the hallmarks of Stiller's attention to detail, serving up an action that's ready for the challenges of creating a dream precision rifle for tactical or hunting adventures.
Stiller's TAC300 action, marked by its bead-blasted 416R stainless steel construction, is engineered to endure the stresses of long-range shooting. The meticulous machining of the receiver to a length of 8.7 inches and its compatibility with the Remington 700 footprint illustrate the adaptability and broad applications of this product.
The bolt design is .700" in diameter, fluted strategically to avoid contact with magazine lips, and is finished with a proprietary coating that provides a frictionless glide during operation. The fluting detail extends to the firing pin, manufactured from stainless steel, which is matched with a chrome silicon spring. This action has a magnum bolt face, incorporating a modified M16 type extractor for its utility and reliability.
The action boasts a side-placed bolt stop, ensuring non-intrusive manipulation. Its design reflects a practical approach, featuring a 90-degree bolt throw that diminishes potential interference and enhances the user's operational comfort.
Adding to the technical specifications, the TAC300's tenon threads are indexed to the top center of the action, allowing any barrel previously fitted to a Stiller action to be interchanged without a compromise in headspace or indexing. This speaks to Stiller's foresight in creating a system that supports flexibility in custom gunsmithing.
This receiver ships in the white, with the bolt coated in black and no top rail. Top rails are availabe separately in various MOA cants
Stiller's legacy in the precision shooting industry emerges from a history of providing custom actions that have been part of winning long-range competitions and successful hunting experiences worldwide. These actions are a reflection of both steadfast performance and the individual's vision of their ideal precision rifle, whether the end use is for tactical shooting or taking down big game at a distance. Stiller was one of the first Remington 700 clone actions, and remains today one of the better bolt and receiver designs for the descriminating precision shooter. The long action serves the long-range shooter well.
