LaRue Tactical built its name chasing tolerances most shops write off as overkill, and the Siete Magnum brings that same obsession to a bolt gun. The heart of this rifle is a CNC-machined billet action bedded into the KRG Bravo chassis, topped with a 24 inch Sendero contour fluted barrel in .300 WSM. The 1:8 twist is faster than what most factory .300 WSM rifles ship with, which means it stabilizes the long, heavy, high-BC bullets that make this cartridge shine well past normal hunting distances. The short magnum case pushes .300 Win Mag class energy out of a stiffer, more efficient package, and the fluted Sendero profile keeps the barrel rigid and quick to shed heat without turning the rifle into a boat anchor.
LaRue didn't cut corners on the touchpoints. The trigger is a genuine Timney breaking crisp at around 2.5 pounds, the kind of unit people usually add to a rifle after the fact. Up front, a proprietary muzzle brake tames the .300 WSM's push so you can stay in the scope and watch your own impacts, and the 5/8×24 threaded muzzle gives you options if you'd rather run a suppressor. The magwell accepts AICS pattern magazines with an oversized drop latch you can work with gloves on, and a LaRue-branded Amend2 mag ships with the rifle. A full-length Picatinny optic rail up top makes mounting glass simple.
At 9 pounds bare and 44.875 inches overall, this is a rifle for elk camp, long shots across canyons, and steel at distances that make lighter sporters feel twitchy. The KRG Bravo stock gives you a solid, adjustable interface that behaves the same from a bench, a bipod, or an improvised field position, all wrapped in a clean flat dark earth finish. If you've been wanting LaRue machining in a magnum bolt action, this is it, and it shows in how the bolt runs and how the groups print.
The magwell is cut for AICS pattern magazines, which is the most common footprint in the precision rifle world. One LaRue-branded Amend2 AICS magazine comes with the rifle, and the oversized drop latch is easy to run even with gloves on. Aftermarket AICS short action magnum mags from brands like MDT and Magpul are widely available.
Yes. The muzzle is threaded 5/8×24, which is the standard pattern for .30 caliber suppressors and muzzle devices. Just remove the factory brake and thread on your can, making sure it's rated for magnum pressures like the .300 WSM produces.
It is, and in a good way. Most factory .300 WSM rifles come with a 1:10 twist, which limits you to lighter bullets. The faster 1:8 twist on the Siete Magnum stabilizes heavy, high-BC projectiles in the 200 grain and up range, which hold velocity and buck wind far better at extended distances.
It genuinely does both. At 9 pounds with a rigid Sendero fluted barrel and the adjustable KRG Bravo stock, it's stable enough for steel and match-style shooting, while the .300 WSM chambering carries plenty of punch for elk, moose, and other big game. The muzzle brake and crisp Timney trigger make it pleasant to shoot in either role.
