The Rock River Arms Fred Eichler Series is a premium line of AR-15 platform rifles strategically optimized for extreme precision, rapid target acquisition, and rugged durability during predator and varmint hunting. Developed in collaboration with renowned professional hunter Fred Eichler, these rifles are designed to be lightweight, easy to maneuver in heavy brush, and exceptionally accurate under sub-zero or fast-paced "running and gunning" conditions.
The primary variants within the lineup include the foundational LAR-15 Fred Eichler Series Predator, the upgraded Predator2, and the weight-saving Light Predator2L.
Core Technical Specifications
Caliber Optimization: Every rifle features a .223 Wylde chamber. This hybrid chamber safely accommodates and maximizes accuracy for both 5.56mm NATO and .223 Remington ammunition.
Match-Grade Barrel: Equipped with a 16-inch fluted, bead-blasted stainless steel barrel featuring a 1:8 twist rate to stabilize heavier hunting bullets. The barrel undergoes specialized cryogenic treatment to increase physical longevity, facilitate easy cleaning, and ensure strict consistency across rapid strings of fire.
Signature Handguard: Features a free-floating handguard machined with a distinctive coyote paw-print CNC design. This artistic choice serves a structural purpose by acting as a heat sink to dissipate barrel heat.
Precision Trigger: Outfitted with a chromed RRA National Match Two-Stage Trigger paired with a non-reflective Parkerized shoe. It breaks smoothly to guarantee an accuracy standard of 3/4 to 1 MOA right out of the box.
Key Ergonomic & Field Features
Cold-Weather Readiness: Includes an oversized winter trigger guard specifically shaped to accommodate thick gloved hands. A BCMGUNFIGHTER medium-latch charging handle offers aggressive texture for positive manipulation in freezing field conditions.
Recoil Management: Built with a proprietary Fred Eichler Series directional-port muzzle brake (or Frontier Edge Brake). This device redirects expanding gases to virtually eliminate muzzle lift, allowing the hunter to keep eyes locked through the optic for quick follow-up shots.
Modular Interface: The full-length Picatinny top rail seamlessly bridges the forged A4 upper receiver to allow clean mounting for high-magnification scopes, thermal systems, or night vision optics. Integrated 2.5-inch rail sections sit permanently at the 3, 6, and 9 o'clock muzzle positions to securely anchor bipods, flashlights, or laser setups.
Premium Furniture: Ships standard with an ergonomic, textured Hogue rubber pistol grip and options for either a fixed A2 operator stock or a 6-position adjustable Operator CAR utility stock.
Notable Model Iterations
Fred Eichler Series Predator2: The baseline production variant utilizing the single-piece machined aluminum handguard with permanent accessory rails at the muzzle end.
Fred Eichler Series Light Predator2L: An ultra-agile variant replacing the aluminum handguard with an extended-length carbon fiber free-float handguard. It shaves down the total rifle weight to a mere 6.9 pounds to reduce fatigue during extended cross-country treks.
Only 40 rounds have been Fired through this Rifle.

Shopping at Guns.com gives you the backing of a company that is committed to your satisfaction. And unlike our competitors, it extends beyond the buying process. We get the FFL from your store – others make you find it, copy it, and fax it. We have a generous return policy, and handle everything – you don’t have to go back to the store. And our Rangemasters are here to answer all your questions about our products or process. We're bringing a level of service to the online gun buying experience that is unheard of.
Many online gun sales actually take away from your local community. Instead of buying a gun that’s on your local store’s shelf, most retailers drop ship it from a warehouse in another state. At Guns.com, if an FFL is part of our network, we sell THEIR guns first whenever possible. That way, we’re helping small businesses in your community AND if they have it in stock, you can pick your gun up IMMEDIATELY – it’s how business should be done.
Most everything can be easily bought online these days. But for some reason, buying a gun online can be complicated. Most websites are poorly organized, don’t tell you a lot about what you’re buying, and leave you on your own to figure out what you want. Guns.com is built to be simple – easily organized products, useful descriptions from experts, and support to guide you to the right choice. Spend your time enjoying the gun you want, not getting frustrated with a complex website that makes gun buying hard.
