Sig Sauer Cross STX 308 Win 20" Threaded Barrel Folding Stock

The Sig Sauer Cross STX delivers precision rifle performance in a compact, lightweight platform engineered for versatility. This bolt-action rifle combines modern materials with proven ballistics to create a hunting and tactical rifle that performs across multiple disciplines.

What Makes This Different

The Cross STX features a one-piece aluminum receiver with integrated 20 MOA Picatinny rail, eliminating the need for separate scope bases while providing optimal long-range trajectory compensation. The free-floating M-LOK handguard ensures consistent barrel harmonics, while the folding stock reduces overall length by 7 inches for transport and storage. This design approach delivers sub-MOA accuracy potential in a package weighing just 6.5 pounds.

Key Features

• 20-inch threaded barrel (5/8x24 TPI) ready for suppressors and muzzle devices
• Aluminum folding stock with adjustable length of pull and comb height
• M-LOK free-float handguard for accessory mounting and heat dissipation
• Integrated 20 MOA Picatinny rail machined into receiver
• 10-round detachable magazine with steel construction
• Single-stage trigger with crisp break and minimal overtravel
• Black anodized finish for corrosion resistance and reduced glare

Field performance centers on the rifle's ability to maintain accuracy across temperature extremes and extended shooting sessions. The aluminum construction provides thermal stability while the free-floating barrel eliminates pressure points that affect precision. Competition shooters benefit from the adjustable stock geometry, while hunters appreciate the compact folded profile for blind and vehicle transport.
