Description
The Rock River Arms LAR-8 Predator HP .308, 20″ Barrel W/Muzzle Brake, Operator CAR Stock, 20 Rd Mag is a purpose-built, semi-automatic .308 Winchester rifle designed for precision engagement at extended ranges. It combines a heavy-profile 20-inch barrel with a stabilizing muzzle brake and a robust, fully-adjustable stock system, creating a platform ready for demanding field use right out of the box.

Who This Rifle Is For
This is for the shooter who has graduated from plinking and needs a serious tool for a specific job. It’s for the hunter sitting a long bean field edge where a 300-yard shot on a coyote or deer is a real possibility. It’s for the tactical competitor who needs a dependable .308 platform for dynamic rifle matches where power and precision are scored equally. It’s also for the prepared individual who understands that a semi-automatic .308 offers a formidable capability for home defense in a rural setting where engagement distances can be measured in acres, not feet. The platform is mil-spec compatible in key areas, meaning a wide range of aftermarket AR-10 parts from brands like Magpul or LaRue Tactical can be used for customization.
Pros & Cons
Pros: The heavy barrel and muzzle brake make this one of the softest-shooting .308 semi-autos you’ll handle, turning what is often a punishing caliber into a manageable one. The two-stage trigger is a significant upgrade over a standard mil-spec unit, giving you immediate feedback and a crisp let-off. The adjustable stock ensures a custom fit for any body type or clothing layer, which is non-negotiable for precision work. Look, a rifle that fits out of the box is a rifle you can trust without modification.
Cons: That 20-inch barrel and robust construction come with a trade-off in weight and maneuverability; this isn’t a rifle you’ll want to clear rooms with. As an AR-10 pattern rifle, it is not compatible with standard AR-15 parts, magazines, or lowers—you’re in the .308 ecosystem now. The price point reflects its premium components and construction, placing it above entry-level options.
Frequently Asked Questions
Q: What type of magazines does this LAR-8 use?
A: The Rock River Arms LAR-8 Predator HP uses proprietary steel magazines. It is designed for reliability with Rock River’s specific mags and is not compatible with Magpul PMAGs or other common AR-10/SR-25 pattern magazines without modification.
