The Sig Sauer Cross Sawtooth .308 Win 12.5" SBR is an ultra-lightweight, compact bolt-action Short Barreled Rifle (SBR) built specifically for maximum packability and high-country hunting. Combining the rigid, one-piece Cross receiver architecture with a premium 12.5-inch Proof Research carbon fiber wrapped barrel, this specialized layout minimizes weight while maintaining rigid thermal control and field accuracy. Designed to optimize performance when running heavily suppressed, the platform is outfitted with a full-length alloy M-LOK handguard integrated with a bottom ARCA-Swiss rail for immediate tripod clamp attachment. Complete operations feature a short-throw bolt mechanism, ambidextrous safeties, and a fully skeletonized, folding precision stock that secures tightly over the bolt handle during transport. The entire complete firearm package comes complete with a 12.5-inch Proof Research carbon fiber wrapped match barrel, a Moss Green Cerakote one-piece chassis, an adjustable 2-stage match trigger, and one 5-round Magpul AICS pattern magazine.
