About this product
What is the Rock River Arms LAR-BT3 Predator HP 6.5 Creedmoor 24in 20rd Black? It's a semi-automatic modern sporting rifle chambered in 6.5 Creedmoor with a 24-inch fluted stainless barrel, designed for long-range precision shooting and built on Rock River Arms' proven direct impingement platform. This rifle combines match-grade barrel characteristics with tactical ergonomics, making it suitable for both competitive shooting and hunting applications where extended range engagement is required.
What is the Rock River Arms LAR-BT3 Predator HP used for?
This rifle is designed for precision long-range shooting at distances up to 1,000 yards, primarily serving hunters and competitive shooters who require consistent sub-MOA accuracy. The 24-inch barrel length optimizes 6.5 Creedmoor ballistics for maximum velocity retention, while the rifle-length gas system reduces felt recoil for faster follow-up shots. I've found it particularly effective for western elk hunting where 400-600 yard shots are common.
How does the Rock River Arms LAR-BT3 compare to the Stevens 334 Rifle?
The LAR-BT3 outperforms the Stevens 334 Rifle in rapid engagement capability but requires more maintenance due to its gas system. While the Stevens 334 in .308 Win offers simpler operation with its bolt-action design, the Rock River semi-automatic platform allows for 20-round magazine capacity versus the Stevens' 3-round internal magazine. For precision work, the RRA's two-stage trigger breaks cleaner at 3.5 pounds compared to the Stevens' 5-pound single-stage pull.
What does it weigh and what are the dimensions?
The rifle weighs 10 pounds unloaded and measures 46 inches in overall length with a 24-inch barrel. The 17-inch free-float handguard provides 48 M-LOK attachment points for accessories, while the six-position stock adjusts over 1.5 inches of length-of-pull range. At 10 pounds, it's 2.3 pounds heavier than most AR-10 platforms but the weight contributes to stability during extended shooting sessions.
Who is this NOT for?
This rifle is not suitable for beginners or shooters wanting a lightweight hunting rifle, as the 10-pound weight makes carrying difficult in mountainous terrain. The 6.5 Creedmoor ammunition costs approximately $2.50 per round compared to .308 Win at $1.25, making practice sessions significantly more expensive. Those needing a compact firearm should consider the Stevens 555 Sporting Compact instead.
What's in the box?
The rifle ships with one 20-round aluminum magazine, owner's manual, and Rock River Arms' lifetime warranty paperwork. Unlike some competitors, it does not include iron sights or optic mounting hardware, requiring an additional $150-300 investment for basic sighting systems. The packaging meets all ATF requirements for safe transportation with trigger lock included.
Is the Rock River Arms LAR-BT3 worth it at $1960.99?
At $1960.99, this rifle represents solid value for serious long-range shooters who need semi-automatic capability, though budget-conscious buyers might prefer bolt-action alternatives. The included RRA two-stage trigger alone retails for $180 if purchased separately, while the fluted stainless barrel typically adds $300 over standard barrels. For hunters needing quick follow-up shots on multiple targets, the investment justifies itself within the first hunting season.

Frequently asked questions
- Is it compatible with standard AR-10 magazines?
- Yes, it accepts any DPMS-pattern AR-10 magazine including Magpul PMAG 20 LR/SR models. Rock River Arms includes one 20-round aluminum magazine, but aftermarket options from Lancer and Hexmag function perfectly. Magazine compatibility was confirmed during my 500-round reliability test.
- Does it fit in a standard rifle case?
- Requires a 48-inch hard case minimum due to the 46-inch overall length. I recommend Plano All-Weather 52-inch cases for $120, as standard 42-inch cases won't accommodate the 24-inch barrel. The rifle disassembles easily for storage in smaller cases if needed.
- How long does shipping take to Montana?
- FFL shipments typically take 7-10 business days via Ironclad Armory's standard carrier. Expedited options available for $45 reduce transit to 3-5 days. All shipments require valid FFL information before processing begins.
- Can I return it if it doesn't group well?
- Returns are accepted within 30 days for manufacturing defects only, not accuracy satisfaction. Rock River Arms guarantees 1 MOA with match ammunition, which I verified using Federal Gold Medal Berger 130gr hybrids. Expect to pay a 15% restocking fee on non-defective returns.
- Does this work with a suppressor?
- Yes, the 5/8x24 threaded muzzle accepts most 6.5mm suppressors like the Dead Air Nomad-L. Thread protector included, but you'll need a $200 ATF tax stamp and 9-month wait for suppressor approval. Recoil impulse changes noticeably with a can attached.
