Description
You’re on a late-season coyote patrol, the wind cutting across the Missouri bottomland. A shadow breaks the treeline at 200 yards—beyond the comfortable reach of a standard 5.56. This is the moment you built a rifle for. The Rock River Arms LAR-6.8 Coyote Carbine AR-15 6.8 Rem SPC 16″ Barrel, Smith Vortex FH, 12.5″ Free Float Rail W/M-Lok, 30 Rd Mag is a purpose-built predator rifle engineered for the hunter who demands terminal performance at intermediate ranges. It delivers the flat trajectory and hard-hitting energy of the 6.8 Remington SPC cartridge in a reliable, lightweight AR platform ready for field use.
When it comes to bridging the gap between an AR-15 and a larger-caliber hunting rifle, the 6.8 SPC cartridge is the answer. This carbine chambers that potent round in a configuration that balances maneuverability with ballistic authority. The 16-inch chrome-lined barrel provides optimal velocity for the 6.8, while the Smith Vortex flash hider keeps your night vision intact during low-light shots. Weighing in at approximately 7.5 lbs unloaded, it’s light enough for all-day carries across rough terrain.
Key Features
The heart of this system is the 6.8 Remington SPC chambering. It drives heavier bullets with more authority than 5.56 NATO, making it decisively effective on coyote, feral hog, and even medium-sized deer within ethical ranges. The cartridge shines from a 16-inch barrel, and Rock River Arms uses a quality 1:11 twist rate to stabilize a wide range of hunting and tactical projectiles.
Control is handed to you by the 12.5-inch free-float rail with M-Lok attachment points. This rail gives you a solid, consistent handguard that won’t shift point of impact with pressure, and the M-Lok system lets you mount lights, lasers, or grips directly and cleanly without bulky adapters. The rifle is drop-in ready for a standard AR-15 carbine stock and pistol grip, allowing for immediate customization to fit your frame. It ships with a 30-round magazine, giving you ample capacity for extended outings or follow-up shots.
Built on a forged aluminum upper and lower receiver set, this is a durable platform. The two-stage national match trigger is a standout feature, offering a crisp, predictable break that enhances accuracy when making precise shots on target. The rifle is compatible with most standard AR-15 parts and accessories, meaning you can use Magpul furniture, Geissele triggers, or Radian safeties if you choose to personalize it further.
