Description
You’re glassing a ridgeline at last light, the wind in your face. A coyote silhouette appears at 200 yards, a fleeting chance. You need a rifle that’s steady, reliable, and hits where you look. That’s the mission behind the Rock River Arms LAR-15 Fred Eichler Series Predator AR-15, 223/5.56 16″ Barrel Operator A2 Fixed Stock Tan. It’s a purpose-built varmint and predator rifle designed from the ground up for field-ready precision and rugged dependability.
This isn’t a rack-grade carbine. It’s a specialized tool engineered for the hunter who demands more from their AR platform. The foundation is a forged 7075-T6 aluminum upper and lower receiver set, providing a rigid, wobble-free platform. The heart of the system is the 16-inch chrome-moly steel barrel with a 1:8 twist rate—a versatile middle ground that stabilizes both lighter varmint loads and heavier 69-77 grain match ammunition for longer shots. The barrel is button-rifled and features a mid-length gas system for a smoother recoil impulse than a carbine-length system. At 7.5 pounds unloaded, it’s light enough for all-day carries but has the heft to settle quickly on shooting sticks or a bipod.
Key Features
The Predator HP handguard is where this rifle separates itself. It’s a free-float tube that provides a consistent point of impact regardless of how you grip it or where you rest it. The full-length top Picatinny rail is uninterrupted, giving you unlimited optic mounting options, while the sides and bottom feature RRA’s proprietary locking attachment points for sling swivels or a bipod. The fixed A2 stock offers a solid, consistent cheek weld and houses the rifle’s internal cleaning kit—a nod to practical field use. The two-stage national match trigger is the crown jewel. It breaks cleanly at around 4.5 pounds, eliminating creep and providing the crisp let-off needed for precise shots on small targets. This rifle is drop-in ready for your scope and a sling; no gunsmithing is required to get it into the field.
Look, when you’re waiting in a blind or navigating a fence line, you need gear that works without fuss. The tan Cerakote finish isn’t just for looks; it provides durable corrosion resistance against Missouri dew and dust. The rifle ships with one 20-round magazine, a practical capacity for hunting scenarios. The entire package, priced at $1550.99, represents a significant value for a rifle with these high-end features typically found on custom builds. It’s available at firearms-missouri.com for Missouri residents and nationwide.

Pros: The exceptional two-stage trigger and free-float handguard deliver outstanding out-of-the-box accuracy. The fixed stock and mid-length gas system make for a very soft-shooting rifle. The finish and construction are built to handle hard use in the elements. It’s fully compatible with standard AR-15 magazines and many mil-spec parts.
Cons: The fixed A2 stock length cannot be adjusted, which may not suit all shooters. The proprietary handguard attachment system limits aftermarket rail section options compared to a standard M-LOK or KeyMod system. The 20-round magazine is ideal for hunting, but you’ll want to pick up some standard 30-round PMAGs for the range.
Who It’s For: This rifle is for the serious varmint hunter, predator caller, or the shooter who uses an AR for precision field work. It’s for the person who values a clean trigger pull and a stable platform over tactical modularity. If your primary need is a dependable, accurate rifle for hunting from a truck, ATV, or stand—one that can also serve as a capable distance trainer—this is your tool.
Frequently Asked Questions
Q: Is the barrel threaded for a muzzle device?
A: Yes, the barrel features a standard 1/2″-28 thread pattern under the included A2-style flash hider. This allows for easy installation of a muzzle brake, compensator, or sound suppressor (with proper paperwork).
Q: Can I use .223 Wylde chambered ammunition in this rifle?
A: Absolutely. While the spec sheet lists .223/5.56, Rock River Arms typically uses a .223 Wylde chamber in their match and predator barrels. This hybrid chamber safely fires both .223 Remington and 5.56 NATO rounds with enhanced accuracy.
Q: What optics mount best on this rifle?
A: The full-length top rail accepts any standard Picatinny/Weaver scope rings or mount. For predator hunting, a low-to-mid magnification variable optic (like a 1-8x or 2-10x) from brands such as Vortex, Leupold, or Primary Arms is an ideal match for this rifle’s capability.
