The Diamondback DB15 Gold .350 Legend 16in M-LOK 5rd is a semi-automatic AR-platform rifle built for hunters and shooters who want a reliable, compact, and hard-hitting firearm in a straight-wall caliber. Chambered in .350 Legend, it delivers the energy needed for deer and hogs at moderate ranges, with a 16-inch barrel and a 15-inch M-LOK handguard that keep it maneuverable in tight spots. Forged 7075-T6 aluminum receivers and a Magpul CTR stock and MOE-K2 grip give it a solid, ergonomic foundation right out of the box.

Key Features
- .350 Legend Chambering — Why it matters: This straight-wall cartridge meets hunting regulations in several states that restrict bottleneck calibers, and it delivers .30-30-like energy with less recoil, making it a great choice for youth or new hunters.
- 16-Inch Barrel with Black Nitride Finish — Why it matters: The 1:16 twist rate stabilizes common .350 Legend bullets, while the nitride treatment resists corrosion and fouling, keeping the bore clean and accurate through long range sessions.
- 15-Inch M-LOK Handguard — Why it matters: The free-float design improves accuracy by removing barrel pressure, and the M-LOK slots let you attach lights, bipods, or sling mounts exactly where you need them for a custom setup.
- Magpul CTR Stock and MOE-K2 Grip — Why it matters: The CTR stock locks tight with no wobble and adjusts for length of pull, while the K2 grip has a more vertical angle that reduces wrist fatigue during extended shooting.
- 5-Round Magazine Included — Why it matters: A 5-round capacity is compliant in many states with magazine limits, yet still gives you enough rounds for follow-up shots on game or target strings.
Who It’s For
This rifle is for the hunter who wants a lightweight, straight-wall AR for deer or hogs, especially in states like Ohio, Indiana, Michigan, and Pennsylvania where .350 Legend is legal. It also fits the family shooter who wants a low-recoil centerfire that younger or smaller-framed shooters can handle confidently at the range. If you need a truck gun or a compact brush rifle that runs on AR familiarity, this DB15 Gold is a solid pick.
Pros & Cons
- Pros: Low recoil for a big-bore cartridge, accurate free-float barrel, quality Magpul furniture, reliable gas system, and a price point under $900 that beats many competitors.
- Cons: The 5-round magazine is limiting for range practice — you may want to buy extra 10-round mags separately. Also, .350 Legend ammo can be scarcer than 5.56 or .223 in some areas, so stock up when you find it.

The DB15 Gold is the only one here chambered in .350 Legend, making it the clear choice for straight-wall hunting. The Zev OZ9 is a high-end pistol, not a direct competitor, but shows the price difference for a custom build. The Geissele Super Duty is a premium 5.56 AR with a mid-length gas system that cycles softer, but it costs nearly twice as much and isn’t legal for straight-wall seasons.
FAQ
No buyer questions were provided for this product. Below are common questions we hear from customers looking at this rifle.
What states allow .350 Legend for deer hunting?
States with straight-wall cartridge regulations, including Ohio, Indiana, Michigan, Pennsylvania, Iowa, Illinois, and several others. Always check your local DNR rules before the season.
Can I use standard AR-15 magazines with this rifle?
Yes, the DB15 Gold uses standard AR-15 lower receivers and accepts .350 Legend-specific magazines. The included 5-round mag is a good start, but 10-round options from companies like CMMG or Amend2 work well.
Is the barrel threaded for a suppressor or muzzle brake?
Yes, the 16-inch barrel comes with a standard 5/8×24 thread pattern, so you can add a .350 Legend-compatible suppressor or brake. Just make sure the muzzle device is rated for the cartridge pressure.
How does the recoil compare to a .223/5.56 AR?
The .350 Legend has noticeably more recoil than 5.56, but it’s still mild — roughly equivalent to a .30-30 lever action. Most new shooters find it manageable, especially with the Magpul CTR stock’s buttpad.
