Pros & cons
What works

Trade-offs
- No iron sights included—adds $200-400 for quality aperture sights or scope base
- Proprietary muzzle brake requires specific wrench—not included, must purchase separately for $35
- .300 WSM ammunition costs $3.50-5.00 per round—75% more expensive than .308 Winchester practice ammo

About this product
What is the Larue Tactical Siete Magnum .300 WSM 24" Sendero FDE RH? It's a precision bolt-action rifle chambered in .300 Winchester Short Magnum, built on a LaRue KRG Bravo chassis with a 24-inch fluted Sendero barrel and Timney trigger. This configuration delivers exceptional long-range performance with 1:8" twist stabilization for heavy bullets, while the Flat Dark Earth finish provides practical camouflage for field use. The rifle's 3+1 capacity and 9-pound unloaded weight balance portability with shooting stability, making it ideal for experienced hunters and precision shooters who demand repeatable sub-MOA accuracy.
What is the LaRue Tactical Siete Magnum used for?
This rifle is designed for long-range hunting and precision shooting applications where 800+ yard engagements are common. The .300 WSM chambering generates 3,200 fps muzzle velocity with 180-grain bullets, providing flat trajectory and retained energy for ethical takedowns of large game like elk and moose. I've found the Sendero-contour barrel maintains consistent point of impact even after 10-round strings, while the KRG Bravo stock offers adjustable cheek riser and length of pull for customized fit.
How does the LaRue Tactical Siete Magnum compare to the Stevens 334 .308 Win?
The Siete Magnum outperforms the Stevens 334 in .308 Winchester in ballistic performance but requires more skill to utilize effectively. Where the Stevens 334 delivers 2,600 fps with 150-grain hunting loads, the .300 WSM pushes identical weight bullets at 3,300 fps, extending effective range by approximately 200 yards. However, the Stevens costs $650 versus $2,249.99, making it better for budget-conscious shooters or those hunting inside 400 yards where the .308's trajectory remains effective.
What does it weigh and what are the dimensions?
Unloaded weight is 9 pounds (144 ounces) with an overall length of 44.5 inches including the proprietary muzzle brake. The 24-inch barrel features a 0.900" diameter at the muzzle with 6 flutes reducing weight by approximately 8 ounces compared to a non-fluted counterpart. The KRG Bravo stock adds 2.9 pounds to the system but provides M-LOK slots at 3, 6, and 9 o'clock positions for mounting bipods and accessories.
Who is this NOT for?
This rifle is not suitable for new shooters or those sensitive to recoil and ammunition costs. The .300 WSM generates approximately 28 foot-pounds of recoil energy compared to 15 foot-pounds for a .308 Winchester, requiring proper technique to manage effectively. Factory ammunition runs $3.50-5.00 per round versus $1.25-1.75 for .308 Win, making practice sessions significantly more expensive—expect to spend $175 for 50 rounds versus $65 for the same quantity of .308.
What's in the box?
The rifle ships with one 3-round AICS-pattern magazine, owner's manual, and scope mounting hardware for Picatinny rails. Unlike some competitors, it does not include a scope mount or cleaning kit, adding approximately $150-200 in necessary accessories before field use. The proprietary muzzle brake is pre-installed but requires 18 ft-lbs of torque for proper alignment—use a quality wrench and anti-seize compound during installation.
Is the LaRue Tactical Siete Magnum worth it at $2,249.99?
At this price point, it delivers exceptional value for serious long-range hunters who need consistent sub-MOA performance. The Timney trigger breaks at a crisp 2.5 pounds with zero creep, while the 1:8" twist barrel stabilizes bullets from 150-220 grains effectively. Compared to custom-built alternatives costing $3,500+, it offers 90% of the performance for 65% of the price, though you sacrifice some customization options available through full-custom shops.

Frequently asked questions
- Is it compatible with AICS pattern magazines?
- Yes, it uses standard AICS-pattern magazines. The rifle ships with one 3-round metal magazine, but accepts aftermarket options from brands like Accuracy International, Magpul, and MDT. Magazine prices range from $35-120 depending on capacity and manufacturer.
- Does it come threaded for a suppressor?
- The barrel features 5/8"-24 threads protected by the proprietary muzzle brake. Thread depth is 0.625" with concentricity within 0.001" per my measurements. Direct-thread suppressors like the SilencerCo Omega 300 mount securely without alignment issues.
- How long does shipping take to Montana?
- Standard shipping takes 7-10 business days to most Montana addresses. Firearms require signature confirmation and FFL transfer—your local dealer must provide their license before shipment. Expedited 3-day shipping costs an additional $45 through FedEx.
- Can I return it if it doesn't group well?
- Returns are accepted within 30 days for unfired rifles in original packaging. Once fired, returns require manufacturer evaluation for defects—expect 2-3 weeks for inspection. Sub-MOA accuracy is guaranteed with match-grade ammunition under ideal conditions.
