LaRue built its name on hyper-accurate rifles and rock-solid mounts out of Leander, Texas, and the Siete Magnum carries that reputation into serious magnum territory. Chambered in .300 Winchester Short Magnum, this bolt gun feeds from a 3+1 capacity setup with an AICS-pattern magazine system, so spare mags are easy to find and swap. The .300 WSM cartridge delivers full .300 Win Mag class performance from a short action, which means a stiffer receiver, faster bolt throw, and a rifle that balances better in the field.
The 24 inch Sendero contour barrel gives the Siete Magnum the stiffness for consistent groups when the barrel heats up, while the fluting cuts weight and helps shed heat between strings. The 1:8 twist stabilizes the heavier, high-BC .30 caliber bullets that make this cartridge shine at distance. Up front, LaRue's proprietary muzzle brake knocks the recoil down to something you can spot your own impacts through, which matters a lot more than people think when the animal or target is way out there.
Instead of a flexy factory stock, LaRue dropped this action into a KRG Bravo, a chassis-backboned stock with proper ergonomics, solid bedding surfaces, and adjustability where it counts. Behind it all sits a Timney trigger with the kind of clean, predictable break that lets you get the most out of a rifle like this. All in, the package runs 44.875 inches overall and weighs 9 pounds, right in the sweet spot for a precision rig you can still carry.
This is a rifle for the hunter or long-range shooter who wants magnum energy on target without giving up precision-rifle features. Elk at distance, open-country mule deer, or just stretching a magnum out past where most rifles get uncomfortable, the Siete Magnum in gray is set up to do the work right out of the box. Top it with quality glass and go shoot it.
It runs AICS-pattern magazines, which is the most common footprint in the precision rifle world. That means spare mags from KRG, MDT, Magpul and others are widely available. The rifle gives you a 3+1 capacity in .300 WSM and ships with one magazine.
.300 WSM is a stout cartridge, but this rifle is well set up to handle it. At 9 pounds with a heavy Sendero contour barrel and LaRue's proprietary muzzle brake up front, felt recoil is far softer than a typical sporter-weight magnum. Most people find they can stay on the scope and watch their own hits.
Yes, and it's one of the smarter choices on this rifle. A 1:8 twist is faster than most factory .300 WSM barrels and will stabilize long, high-BC bullets in the 200 grain and up range. That opens the door to modern long-range loads that lighter-twist barrels struggle with.
It comes from the factory with a Timney trigger, a name most rifle guys know well. Expect a clean, crisp break with minimal creep, the kind of trigger people usually pay to upgrade to. Paired with the KRG Bravo stock, it makes consistent precision work much easier.
