Key Features
- 18-inch Sporter Contour Barrel — Balances weight savings with stiffness. Why it matters: You can carry this rifle all day on a two-gun course and still hit a 400-yard plate without barrel whip.
- Larue Siete Trigger System — A two-stage trigger with a crisp 2.5 to 4 lbs adjustable pull. Why it matters: Consistent break means you stop chasing the trigger and start calling your shots.
- Oversized Bolt Handle with Fluted Body — Faster cycling and reduced friction. Why it matters: When the timer is running, you need positive extraction and a bolt that doesn’t bind under speed.
- Integral 20 MOA Picatinny Rail — Machined directly into the receiver. Why it matters: No lapping, no shims—mount your scope and trust that the base is true to the bore axis.
- Detachable Box Magazine (12+1) — Uses standard SR25-pattern mags. Why it matters: Reloads are faster than internal box magazines, and you can carry spares that work across your AR-10.
Who It’s For
This rifle is for the Precision Rifle Series shooter who wants a factory gun that holds zero under recoil and shoots 0.6 MOA with match ammo. It’s also for the tactical competitor who needs a 308 that transitions quick and doesn’t hang up on barricades. If you’re a hunter who shoots steel during the off-season, the Siete LE bridges that gap without compromise.
Pros / Cons
- Pro: Sub-MOA guarantee right out of the box—Larue test-fires each rifle before shipping.
- Pro: The 18-inch barrel keeps velocity high enough for 308 to 800 yards but short enough for suppressor use.
- Con: The 12+1 magazine capacity is generous, but the magwell is tight with some aftermarket SR25 mags—stick to Magpul or Larue-branded for reliable feeding.
- Pro: The two-stage trigger is adjustable without removing the action from the stock.
- Con: Weight at 9.4 lbs is on the lighter side for a precision rifle, which means more felt recoil than a 12-lb chassis gun.
Comparison: Larue Siete LE vs. Geissele Super 700 vs. Timney 700 TR
| Feature | Larue Siete LE | Geissele Super 700 | Timney 700 TR |
|---|---|---|---|
| Barrel Length | 18 inches | 20 inches | 22 inches |
| Trigger | Adjustable two-stage (2.5-4 lbs) | Two-stage (2.5 lbs fixed) | Single-stage (1.5-2.5 lbs) |

| Price | $2,249.99 | $2,999.99 | $1,799.99 |
| Best Use | Competition / tactical | Long-range benchrest | Hunting / PRS light |
The Larue gives you detachable mags and a lighter build than the Geissele, while the Timney is cheaper but lacks the integral rail and oversized bolt handle. For competition shooters who value reload speed and portability, the Siete LE is the smarter pick.
FAQ
Does this rifle accept standard Remington 700 triggers?
No. The Larue Siete uses a proprietary trigger system designed by Larue. It is not compatible with R700 drop-in triggers. The included trigger is adjustable from 2.5 to 4 lbs and is already optimized for precision work.
What scope base does the integral rail accept?
The integral 20 MOA Picatinny rail accepts any standard Picatinny-compatible scope rings or one-piece mounts. No need for a separate base—just mount your rings directly.
Can this rifle be converted to left-hand?
As of April 2026, the Siete LE is only offered in right-hand configuration. Left-handed shooters should look at the Larue OBR or custom actions.
What is the twist rate on the barrel?
The 18-inch Sporter barrel has a 1:10 twist rate, optimized for 168 to 175 grain match bullets. This is standard for 308 Win precision loads.
Does the rifle come with a muzzle device?
Yes, it ships with a Larue 5/8×24 thread protector. You can add your own brake or suppressor—the barrel is threaded and timed for standard 308 muzzle devices.
