Description
The Rock River Arms Varmint A4 LAR-8 AR-10 308 26″ Barrel 22″ Extended Rail is a purpose-built, long-range precision rifle built on Rock River’s reliable LAR-8 platform. It’s designed for shooters who need consistent accuracy at distance, offering a heavy 26-inch barrel and an extended 22-inch free-float rail for maximum stability and accessory mounting. This rifle ships to Missouri and compliant US states, providing a solid foundation for varmint control or target shooting without a custom shop price tag.
Key Features
- 26-Inch Heavy Barrel: A cold hammer-forged, chrome-moly barrel provides the rigidity needed for tight groups and manages heat during extended shooting sessions.
- 22-Inch Extended Quad Rail: Offers ample real estate for bipods, night vision, and long-range optics without crowding the handguard.
- Two-Stage National Match Trigger: Delivers a clean, predictable break essential for precision shooting, a significant upgrade over a standard mil-spec unit.
- Fully Free-Floated Handguard: Isolates the barrel from external pressure, ensuring point of impact stays consistent whether you’re on a bipod or a barricade.
- A4 Fixed Stock: Provides a stable, repeatable cheek weld, which is a practical choice for a dedicated bench or prone rifle.

Weighing in at approximately 11.5 pounds unloaded, this is not a lightweight patrol rifle—it’s a specialized tool. The heft, combined with that long barrel, soaks up recoil and steadies your aim. Here’s the thing—at $1597.06, you’re getting a complete, ready-to-shoot system with a premium trigger and rail that would cost hundreds more to add to a base model. It’s built to accept common AR-10 pattern magazines, and the upper and lower are machined to tight tolerances for a solid fit. No gunsmithing required; it’s assembled and ready for your optic and bipod.
Who This Rifle Is For
This rifle is built for the budget-conscious precision shooter. Think prairie dog towns, long-range steel targets, or disciplined benchrest sessions. It’s for the hunter who needs to make ethical, long-distance shots on coyotes or groundhogs. If you’re looking for a lightweight carbine for home defense or dynamic shooting, this isn’t it. But if your priority is hitting small targets far away without spending $3,000, this Rock River model makes a compelling case.
Pros & Cons
Pros: The value is clear. You get a match-grade barrel and trigger out of the box on a proven platform. The extended rail offers unmatched flexibility for accessories. Rock River’s reputation for quality means it should be reliable and accurate. It’s a complete, no-fuss package.
Cons: The weight and length make it cumbersome for anything but stationary shooting. The fixed stock isn’t adjustable for different shooters. As an AR-10 pattern, some parts aren’t as universally interchangeable as the AR-15, but it’s compatible with many DPMS-pattern components and magazines.
Frequently Asked Questions
Q: What magazines does this LAR-8 use?
A: It uses Rock River Arms LAR-8 magazines or other compatible .308 AR magazines designed for the DPMS pattern. We recommend testing compatibility, but many common brands like Magpul PMAGs for the SR-25/LR-308 platform work well.
Q: Is the barrel threaded for a muzzle device?
A: Yes, the 26-inch barrel comes with a standard thread pattern, allowing you to add a muzzle brake, compensator, or suppressor mount. A standard A2 flash hider is installed from the factory.
Q: Can I swap the fixed stock for a collapsible one?
A: Technically yes, but it requires changing the entire buffer tube assembly to a carbine system. It’s a significant parts swap that adds cost and complexity, defeating the purpose of this rifle’s dedicated design. The fixed stock is a feature for stability, not a limitation.
