This robust receiver setup is engineered to meet the stringent requirements of competitive shooters and precision rifle enthusiasts alike. Let's explore the standout features and specifications that make this receiver a top choice for building a high-precision rifle.

Unmatched Material and Construction The Ruckus Tactical receiver is crafted from pre-hardened, aircraft-certified 416 Stainless Steel, ensuring superior strength and durability. This choice of material guarantees that the receiver maintains its dimensional stability even after rigorous use, which is essential for maintaining long-term accuracy and performance.

Precision Machining for Guaranteed Accuracy At the core of the Ruckus Tactical's design is a one-piece bolt, precision-machined from aircraft-certified 4340 chrome moly steel. This manufacturing process guarantees a headspace tolerance of +/-.001″, a critical specification for achieving consistent accuracy. The receiver barrel threads are standard at 1.0625” X 16 T.P.I., compatible with Remington 700 dimensions, which broadens the compatibility with a variety of custom and off-the-shelf barrels.

Integrated Tactical Features

  • Picatinny Integral 20 MOA Scope Base: This built-in feature provides a stable and elevated platform for mounting long-range optics, essential for making precise adjustments at varying distances.
  • Integral Recoil Lug: The recoil lug is integrated into the receiver to provide increased surface area, enhancing the receiver's ability to absorb and distribute the recoil generated by heavy calibers like the 338 Lapua.
  • Spiral Standard Fluting: The bolt features spiral standard fluting, which not only reduces the overall weight but also aids in the smooth operation of the bolt, reducing drag and enhancing the cycling speed.

  • Works with hinged floorplates, detachable magazines, or single shots, offering flexibility depending on the shooter’s preference or mission requirements.
