Description
There is a reason the Cross-Magnum Sawtooth keeps coming up in conversations about serious backcountry rifles. Sig built it around a one-piece Cross-Magnum receiver and topped it with a 24 inch Proof Research carbon fiber barrel, which is the same barrel maker that custom shops charge a premium for. Chambered in .300 PRC, this thing is made for the hunter who glasses a bull across a canyon and needs a rifle that can close that distance with confidence. Sig backs it up too, since every rifle ships with a sub-MOA test target proving it grouped before it left the factory.
Why the Sawtooth Carries Like a Mountain Rifle
Magnum rifles have a habit of being heavy, but this one comes in around 8.5 pounds with the magazine, which is impressive for a full chassis rifle on a magnum-length action. The folding Cross Precision stock is fully adjustable for length of pull and comb height, and it folds flat against the receiver so the rifle rides better on a pack or in a truck. The handguard is a lightened design with integrated ARCA rail and M-LOK slots, plus dual QD sling points, so tripod work and sling setups are simple. The whole rifle wears a Cerakote Moss finish that shrugs off weather and blends into timber country.
Shooting the Cross-Magnum Sawtooth in .300 PRC
The .300 PRC is a magnum cartridge, no way around it, but the included stainless steel heavy profile radial brake cuts felt recoil by up to 45 percent, which makes spotting your own impacts realistic. The two-stage match trigger is user adjustable from 2.5 to 4 pounds and breaks clean. The 1:9 twist barrel stabilizes the heavy, high-BC bullets that make .300 PRC shine at distance, and the 5/8×24 threaded muzzle means you can swap the brake for a suppressor whenever you want. Feeding comes from a 6-round steel AICS pattern magazine, the safety is ambidextrous, and the receiver is optics ready. It is a lot of rifle in a package you will not mind hauling up the mountain.

Frequently Asked Questions
How accurate is the Sig Cross-Magnum Sawtooth?
Sig guarantees sub-MOA accuracy and every rifle ships with the actual test target it fired at the factory. The Proof Research carbon fiber barrel is a big part of that, and reviewers running quality factory ammo have reported groups well under an inch at 100 yards. With good glass and match-grade hunting loads, this rifle will outshoot most of us.
How bad is the recoil with .300 PRC in a rifle this light?
The .300 PRC generates real magnum energy, but the included stainless radial brake cuts felt recoil by up to 45 percent, which brings it down to a very manageable level. The adjustable stock also lets you get a proper fit, which helps more than people expect. If you run a suppressor instead, the 5/8×24 threads make that an easy swap.
Can I mount this Cross-Magnum Sawtooth on a tripod?
Yes, the handguard has an integrated ARCA rail running along the bottom, so it clamps straight into ARCA-compatible tripod heads with no extra hardware. M-LOK slots are there too for bipods, and dual QD sling points handle carry duty. It is set up well for both field shooting positions and precision work.
Does the stock on the Sawtooth fold, and how compact does it get?
It does. The Cross Precision stock folds against the receiver, bringing the rifle down to roughly 35.6 inches from its 47.1 inch extended length. That makes a real difference when you are strapping it to a pack for a long hike in or fitting it into a shorter case.
