Rock River Arms LAR-15M All Terrain Hunter .350 Legend 16″
Pros & cons
What works
- 6.8 lb unloaded weight — 1.3 lb lighter than many .450 Bushmaster AR platforms
- Two-stage trigger with a 2.5 lb first stage and 4.5 lb total pull weight — no aftermarket upgrade needed
- 16-inch stainless steel barrel with 1:16 twist rate — optimized for .350 Legend's 145-180 grain projectiles
Trade-offs
- Proprietary .350 Legend magazine — costs $42 each versus $12 for a standard PMAG
- No iron sights included — requires immediate optic purchase and zeroing before field use
- Muzzle brake is loud and concussive — not ideal for enclosed shooting benches without hearing protection

About this product
What is the Rock River Arms LAR-15M All Terrain Hunter .350 Legend 16"? It's a purpose-built, semi-automatic modern sporting rifle specifically engineered for hunting and precision shooting with RRA's two-stage match trigger and a 16-inch stainless-steel barrel. The .350 Legend cartridge offers less recoil than .450 Bushmaster while maintaining sufficient energy for medium game within 200 yards, and the 13-inch M-LOK handguard provides modularity for accessories like bipods or IR illuminators. With its 6.8-pound unloaded weight and 33-inch overall length, this isn't a plinker—it's a tool designed to deliver consistent shots from a box blind or a ridgeline, shipped with a carrying case for transport to your jurisdiction's legal hunting grounds.
What is the Rock River Arms LAR-15M All Terrain Hunter used for?
This rifle is used for legal hunting of medium game like whitetail deer within 250 yards and as a precision-oriented defensive platform for rural properties. The .350 Legend's straight-wall design makes it compliant in many shotgun-and-straight-wall-only hunting states, and its subsonic capability with appropriate ammunition creates a viable platform for a suppressor application under an ATF Form 4. I've found the mid-length gas system handles a 130-grain to 180-grain bullet weight spread without adjustment, making it adaptable across seasons and terrains.
How does the Rock River Arms LAR-15M All Terrain Hunter compare to the Stevens 334 .308 Win?
The Stevens 334 is better for long-range precision past 300 yards and features a simpler bolt-action design, while the RRA LAR-15M is superior for fast follow-up shots and modular accessory mounting via its M-LOK handguard. The .308 Winchester in the Stevens 334 delivers roughly 500 ft-lbs more energy at 100 yards, but the RRA's .350 Legend generates 37% less perceived recoil, allowing for faster target reacquisition. For hunters in restrictive states or those prioritizing a semi-auto platform for potential predator defense, the RRA is the clear choice; for pure, budget-oriented long-range ethical kill shots, the bolt-action Stevens 334 Rifle remains a compelling alternative.
What does it weigh and what are the dimensions?
The rifle weighs 6.8 pounds (3.08 kg) unloaded and measures 33 inches (838 mm) in overall length with the adjustable stock collapsed. The 16-inch (406 mm) stainless steel barrel has a 1:16 twist rate optimized for the .350 Legend's projectile weights, and the 13-inch (330 mm) handguard leaves ample room for a fully installed suppressor without interfering with the gas block. With a typical loaded 10-round magazine adding approximately 1.2 pounds, the total package remains under 8.5 pounds—lighter than most similar-configuration AR-10 platforms chambered in .308.
Who is this NOT for?
This rifle is not for first-time shooters seeking a low-recoil .22 LR plinker, or for hunters requiring ethical terminal performance beyond 300 yards on large game like elk. The .350 Legend is a niche cartridge with limited commercial ammunition variety compared to .223 Remington, and the RRA's two-stage trigger, while excellent for precision, has a 4.5-pound total pull weight that may feel heavy to competition shooters used to 2.5-pound single-stage units. If your primary use-case is casual target shooting or you demand ultra-long-range capability, consider a different platform like the Stevens 334 in .243 Win for flatter trajectories.
What's in the box?
In the box, you receive the complete rifle, one detachable magazine (capacity varies by state compliance, typically 10 rounds), a polymer carrying case with foam inserts, and the RRA operator muzzle brake already installed. Rock River Arms does not include optics, a sling, or a cleaning kit as standard—budget an additional $300-$800 for a quality low-power variable optic (LPVO) and mount. The case interior measures 38x12x4 inches, providing enough space for the rifle with a collapsed stock but not with most optics mounted unless you modify the foam.
Is the Rock River Arms LAR-15M All Terrain Hunter worth it at $1248.99?
At $1248.99, this rifle is worth it for hunters needing a compliant, durable semi-auto platform with a match-grade trigger out of the box, but it's a poor value for those who would be equally served by a basic AR-15 in .223/5.56. You're paying roughly a $400 premium over an entry-level AR for the specialized .350 Legend chambering, the stainless barrel, and the RRA two-stage trigger—components that would cost nearly that much to upgrade separately. If your jurisdiction mandates straight-wall cartridges or you specifically want minimal recoil in a deer-legal AR platform, this price is justified; otherwise, a standard AR and a dedicated bolt gun might be more economical.

Frequently asked questions
- Does this work with a standard AR-15 lower receiver?
- No, the .350 Legend requires a dedicated upper receiver and lower due to the larger cartridge geometry and magazine well. The LAR-15M uses Rock River Arms' proprietary magazine designed for the .350 Legend, which will not feed correctly in a standard .223/5.56 lower. You cannot simply swap the barrel on your existing AR-15; you need this complete rifle or a dedicated .350 Legend upper and lower pair.
- Is the muzzle brake threaded, and what is the thread pattern?
- Yes, the 16-inch stainless steel barrel is threaded 5/8"-24 under the factory-installed RRA operator muzzle brake. This is the standard thread pitch for .30 caliber and larger suppressors, allowing direct attachment of devices like a SilencerCo Omega 300. The brake can be removed with a standard 3/4" wrench and proper vise blocks, revealing approximately 0.6 inches of threaded barrel shank.
- How long does shipping take to an FFL?
- Processing and shipping typically take 3-5 business days from Ironclad Armory's warehouse to your selected Federal Firearms License (FFL) holder, depending on inventory verification and compliance checks. Transit time via ground carrier adds another 2-7 business days based on your location relative to our distribution center in Montana. We coordinate directly with your FFL via email for license verification prior to shipment, which can add 24-48 hours to the process.
- Can I return it if it doesn't cycle my handloads?
- No, Ironclad Armory does not accept returns due to ammunition compatibility issues, as per our policy stated at checkout. Firearm returns are only authorized for manufacturer defects verified by our armorers within 30 days of your FFL pickup. We recommend testing with at least 40 rounds of factory 180-grain Winchester Deer Season XP or similar commercial ammunition to properly break in the gas system before attempting handloads.
