SIG SAUER CROSS-Magnum Sawtooth 7mm PRC 20-Inch Rifle

Description

SIG SAUER CROSS-Magnum Sawtooth 7mm PRC Rifle

The SIG SAUER CROSS-Magnum Sawtooth in 7mm PRC is a precision bolt-action rifle built for hunters and shooters who want magnum-class performance in a field-oriented platform. This exact configuration, manufacturer part number CROSS-MAG-7PRC-20B-SAW, combines a 20-inch PROOF Research carbon-fiber-wrapped barrel with the rigid one-piece CROSS Magnum receiver, a folding adjustable precision stock, and a lightweight M-LOK/ARCA handguard. The result is a compact, adaptable rifle designed to balance practical carry characteristics with the accuracy features expected from the CROSS family.

20-Inch PROOF Research Carbon Fiber Barrel

The 20-inch barrel uses a stainless-steel core with a carbon-fiber wrap to reduce unnecessary weight while retaining the stiffness and thermal characteristics valued in a precision rifle. Its 1:8 twist rate is matched to the 7mm PRC chambering, and the muzzle is threaded 5/8×24 with a 90-degree shoulder. SIG installs a stainless-steel heavy-profile radial brake at the factory; the manufacturer states that this brake can reduce felt recoil by up to 45 percent. The shorter 20-inch format also keeps the rifle more manageable when moving through dense terrain or working from compact shooting positions.

Precision-Ready Receiver and Trigger

SIG builds the Sawtooth around the one-piece CROSS Magnum receiver and equips it with a two-stage adjustable match trigger. Trigger pull is adjustable from 2.5 to 4 pounds, allowing the shooter to tailor the feel within the manufacturer’s specified range. A factory 20-MOA Picatinny rail provides a solid starting point for mounting a suitable optic and preserves useful elevation adjustment for longer-range applications. The rifle is shipped SUB-1 MOA certified, with the factory test target included in the box.

Adjustable Folding Stock and Field Controls

The folding precision stock helps shorten the rifle for storage and transport while providing the adjustability needed to establish a consistent shooting position. It uses an AR-compatible PRS-style grip and an ambidextrous AR-style manual safety, making the control layout familiar to many modern rifle users. The curved trigger, bolt action, and adjustable stock work together as a straightforward precision-rifle interface without adding unnecessary complexity.

ARCA and M-LOK Accessory Support

The lightened, free-floating alloy handguard incorporates both ARCA and M-LOK interfaces. ARCA compatibility supports direct use with many tripod heads and shooting supports, while M-LOK slots provide flexible mounting positions for a bipod, sling hardware, or other compatible field accessories. Dual sling points add practical carry options. The handguard and receiver wear a Moss Green Cerakote finish that complements the rifle’s hunting-focused design and adds a durable exterior coating.

Magazine and Feeding System

This model uses an AICS-pattern magazine system and includes one six-round double-stack steel magazine. The detachable magazine supports efficient loading and unloading, while the listed 6+1 capacity provides six rounds in the magazine plus one in the chamber when loaded in accordance with applicable laws and safe handling practices. As with any precision rifle, use only ammunition that matches the marked chambering and follow the manufacturer’s instructions for inspection, loading, and maintenance.
