SIG Cross Rifles

The SIG Cross rifle is SIG’s folding bolt-action hunting rifle. The Cross is a one-piece receiver with a folding precision stock, a 2-stage match trigger, and a free-float handguard so a hunting rifle still packs like a camp gun. The receiver is optic-ready. A factory scope is not installed. Magazines are AICS-pattern on the short-action guns. These are serialized rifles and ship to a licensed FFL.

Every rifle here is a serialized firearm and transfers through a licensed FFL. Optics are not included unless a specific product page says otherwise. Magazines listed on each page are the magazines SIG includes with that model; extra magazines are a separate purchase and must match the action length.

Hunting Cross, TRAX, and Magnum

The original hunting Cross uses a folding precision-adjustable stock and a free-floating M-LOK handguard. The 16-inc .08 Winchester Cross is the compact black stainless configuration. The 18-inch 6.5 Creedmoor Cross uses the same chassis with a longer barrel. The Cross Bronze keeps the 16-inc .08 layout in Bronze Cerakote. The 20-inch 277 SIG Fury Cross uses a cold-hammer-forged barrel for that hybrid cartridge.

TRAX is the compact hunting variant. It keeps the Cross receiver and substitutes a minimalist folding stock, a PDW grip, and an 11.5-inch skeletonized handguard. SIG lists TRAX at 5.9 lb with a 26-inch folded length. The .243 Winchester TRAX and the .308 Winchester TRAX share that chassis and differ by caliber and twist rate.

Cross Magnum is a magnum-length receiver, not a renamed short-action Cross. The coyot .00 Winchester Magnum uses a 24-inch stainless barrel, a radial brake, a PRS-style grip, and a 6-round double-stack steel magazine. A camouflage Magnum in the same chambering is listed separately. Magnum barrels and magazines are not interchangeable with the 5-round short-action hunting rifles.

Sawtooth, STX, and PRS

Sawtooth rifles add PROOF Research carbon-fiber barrels, moss green Cerakote, a lightened M-LOK/ARCA handguard, and a heavy-profile radial brake. SIG certifies Sawtooth rifles as sub-1 MOA and includes a confirmation target. Short-action Sawtooth models include the 16-inc .08, the 18-inch 6.5 Creedmoor, the 24-inch 6.5 Creedmoor, and the 22-inch 6.5 PRC with its 4-round steel magazine.

Magnum Sawtooth rifles use the magnum receiver and a 24-inch carbon-fiber barrel with a 6-round steel magazine. Chamberings in this family includ .00 PRC,.300 Winchester Magnum, and 7 PRC. STX is the 20-inch tactical Cross with a 10-round magazine, a full-length 20-MOA top rail, a PRS grip, and an SLX/SLH suppressor-ready flash hider. The .308 STX is the STX rifle listed here.

PRS is the competition Cross. SIG lists a 13.5 lb steel-structure chassis, a 24-inch heavy stainless barrel, a removable steel ARCA rail, and a 10-round polymer magazine in Concrete Cerakote. The .308 PRS and the 6mm Creedmoor PRS share that layout and differ by caliber and twist rate.

How to Choose Caliber and Barrel Length

Start with chambering, then barrel length, then chassi .08 Winchester appears in 16-inch hunting, TRAX, and Sawtooth rifles, a 20-inch STX, and a 24-inch PRS. 6.5 Creedmoor appears as an 18-inch hunting Cross and as 18-inch or 24-inch Sawtooth rifles. Magnum chamberings in this family ar .00 Winchester Magnum,.300 PRC, and 7 PRC, all on 24-inch Magnum or Magnum Sawtooth rifles. 6.5 PRC is the 22-inch Sawtooth. 277 SIG Fury is the 20-inch hunting Cross. 6mm Creedmoor is the PRS. A shorter barrel favors a compact folded package; a 24-inch barrel favors the longer Magnum, Sawtooth, and PRS rifles.

A folding stock is standard on these rifles, but folded length changes with barrel and stock design. TRAX and the 16-inch hunting Cross fold to about 26 inches. Magnum rifles fold to the mid-30-inch range. PRS remains a 13.5 lb rifle even when folded. Match the magazine to the action: 5-round polymer for most short-action hunting rifles, 4-round steel for the 6.5 PRC Sawtooth, 6-round steel for Magnum rifles, and 10-round polymer for STX and PRS.

Barrel material and muzzle hardware also separate the rifles. Hunting Cross, TRAX, Magnum, STX, and PRS rifles use stainless or cold-hammer-forged steel barrels. Sawtooth rifles use PROOF Research carbon-fiber barrels. Compact hunting and TRAX rifles ship with a thread protector. Magnum and Sawtooth rifles include a radial brake. STX includes an SLX/SLH suppressor-ready flash hider; a suppressor is not part of the rifle.

Magnum and Magnum Sawtooth rifles include a 6-round double-stack steel magazine. STX and PRS include a 10-round polymer magazine. Extra magazines must match that action length.
