The Rock River Arms LAR-15M All Terrain Hunter .350 Legend 16″ is a purpose-built modern sporting rifle that brings real deer-hunting performance to the AR platform. Chambered in the straight-wall .350 Legend, this carbine is legal in many states with restricted rifle calibers for whitetail season. It pairs a 16″ stainless steel barrel with a mid-length gas system for reliable cycling and reduced recoil, making it a solid choice for new hunters and experienced shooters alike.

Key Features
- 16″ Stainless Steel Barrel — WHY IT MATTERS: Stainless steel resists corrosion better than chrome-moly, so you can hunt in rain or snow without worrying about rust. The 1:16 twist rate stabilizes .350 Legend bullets from 150 to 180 grains, giving you flexibility for different game loads.
- Mid-Length Gas System — WHY IT MATTERS: This system reduces felt recoil and keeps the rifle cycling smoothly, even with lower-pressure .350 Legend ammunition. It also extends the life of internal parts by spreading out the bolt carrier velocity.
- RRA Two-Stage Ultra Match Trigger — WHY IT MATTERS: A clean, predictable trigger break helps you shoot tighter groups at the range and make ethical shots on game. The two-stage design gives you a take-up stage then a crisp let-off, perfect for beginners learning trigger control.
- 13″ Lightweight M-LOK Free-Float Handguard — WHY IT MATTERS: The free-float design keeps barrel harmonics consistent for better accuracy, while the M-LOK slots let you mount a bipod, light, or sling without adding bulk. At just 13 inches, it balances well with the 16-inch barrel.
- Hogue Rubber Grip and Adjustable Stock — WHY IT MATTERS: The soft rubber grip reduces hand fatigue during long shooting sessions, and the adjustable stock lets you fit the rifle to different-sized shooters — great for passing the rifle down to a teen or spouse.
Who It’s For
This rifle is built for the family who wants one gun that can do it all: deer hunting, target practice, and teaching new shooters. The .350 Legend cartridge has low recoil and is legal in straight-wall states like Ohio, Michigan, Indiana, and Pennsylvania. It’s also a smart pick for anyone looking to transition from a bolt-action to an AR platform without losing hunting capability.
Pros and Cons
Pros: Reliable mid-length gas system, excellent trigger out of the box, stainless barrel resists weather, M-LOK handguard for accessories, includes a soft carrying case.
Cons: The rifle is a bit heavier than some hunting ARs at 7.5 pounds, which might be noticeable on long hikes. Also, .350 Legend ammunition can be harder to find than .223 or .308 in some rural stores.
