The 24 in PROOF Research carbon-fiber wrapped barrel is free-floated and threaded, capped with a stainless multi-port radial muzzle brake to manage recoil and muzzle rise. Chambered in .300 PRC, the configuration is built around a magnum-length, one-piece receiver designed for strength and a quick-change barrel system.
A full-length 20-MOA 1913 Picatinny top rail runs the receiver for mounting solutions, while the free-float skeletonized handguard integrates ARCA and M-LOK interfaces. There are no optics or iron sights installed.
The folding precision-adjustable stock offers tool-less setup with adjustable cheek height, a 14.0 in length of pull, and adjustable buttpad height and offset. A polymer vertical pistol grip and an oversized cylindrical bolt knob support consistent handling.
Finished in earth-tone green across the receiver, frame, and stock, this USA-made Sawtooth includes factory markings: "CROSS", "MULTI CAL.", and "SIG SAUER INC NEWINGTON, NH USA". Stated capacity is 6+1, and the Sawtooth series carries a certified sub-MOA accuracy claim.
