Description
The Rock River LAR-8 X-1 Rifle, Tan, Operator CAR Stock 18″ Barrel 20 Rd Mag is a .308 Winchester/7.62x51mm NATO battle rifle built on a proprietary, large-frame AR-10 platform. It’s designed for precision and reliability at extended ranges, featuring a mid-length gas system, a free-floated handguard, and a classic CAR-style stock for a proven, no-nonsense tactical profile. This rifle is a serious tool for the shooter who needs a dependable, hard-hitting semi-auto.
I’ve put a few hundred rounds of mixed M80 ball and match-grade ammo through this platform, and here’s what stands out. The 18-inch chrome-moly barrel with a 1:10 twist is a sweet spot—it gives you excellent velocity and accuracy without the unwieldy length of a full 20-inch rifle. The two-stage national match trigger is a standout feature right out of the box; it breaks cleanly at around 4.5 pounds, making precise shots feel intuitive. The tan Cerakote finish isn’t just for looks—it’s a durable layer of protection that holds up to handling and the elements.
- Chambered in .308 Win/7.62 NATO for serious stopping power.
- 18-inch chrome-moly barrel with a 1:10 twist rate, free-floated for accuracy.
- Two-Stage National Match trigger for a crisp, predictable pull.
- Mid-length gas system for reliable cycling and a smooth recoil impulse.
- Operator CAR Stock provides a classic, adjustable length of pull.
- Railed flat-top upper receiver for versatile optic mounting.

So who is this rifle for? Look, it’s for the hunter who wants a capable semi-auto for medium to large game, or the precision-oriented shooter who wants a dependable DMR (Designated Marksman Rifle) platform. It’s also a solid choice for the prepared citizen who values the .308’s versatility for defense at distance. The LAR-8 uses Rock River’s proprietary large-pin pattern, but the good news is that many standard AR-10 parts are mil-spec compatible—you can swap the pistol grip or stock without a gunsmith. That said, the upper and lower are a matched set, so you won’t be mixing this with a DPMS or Armalite pattern receiver.
Pros: The accuracy potential is excellent for a factory rifle, thanks to that free-float handguard and match trigger. The mid-length gas system on a .308 is a great choice—it tames recoil effectively. Build quality is typical Rock River: solid, well-fitted, and reliable. At $2160.92, it’s positioned as a premium, ready-to-run rifle without custom shop prices.
Cons: It’s not light—expect to carry about 9.5 pounds before optics and ammo. The proprietary receiver pattern means you need to be mindful of compatibility for some parts, though magazines are standard SR-25/DPMS pattern. The included 20-round mag is great, but have you priced .308 ammo lately? Feeding this beast is an investment in itself.
Frequently Asked Questions
Q: What magazines does this LAR-8 use?
A: It uses the common SR-25/DPMS pattern .308 magazines. The rifle comes with one 20-round steel magazine, and you can easily find Magpul PMAG® LR/SR GEN M3 or other compatible brands as extras.
Q: Is the barrel threaded for a muzzle device?
A: Yes, the 18-inch barrel comes with a standard A2 flash hider, which is threaded 5/8″-24. You can remove it to install a muzzle brake, compensator, or suppressor mount—just remember to check local and federal regulations.
Q: Is this rifle optics-ready?
A: Absolutely. The flat-top upper receiver has a full-length Picatinny rail, so you can mount any standard scope rings, red dot, or prism sight. Many shooters opt for a variable 1-6x or 3-9x scope to take full advantage of the .308’s effective range.
