The Diamondback DB10 .308 Win 16″ M-LOK Rifle is a no-nonsense AR-style semi-auto built for ranch work, coyote control, and steel ringing. Chambered in .308 Winchester, it runs on a mid-length gas system and a 16-inch chrome-moly barrel with a 1:10 twist. Forged 7075-T6 aluminum receivers and Magpul MOE furniture keep it tough and light. Includes a Gen M3 20-round PMAG. Price: $976.97.

Key Features
- 16-inch chrome-moly barrel with 1:10 twist — Stabilizes 147-175 grain loads for consistent accuracy out to 600 yards. Why it matters: You get reliable expansion on varmints and solid hits on steel without a heavy 20-inch pipe.
- Mid-length gas system — Smoother cycling and less felt recoil than carbine-length. Why it matters: Faster follow-up shots when a coyote breaks cover or a steel target needs a second hit.
- Forged 7075-T6 aluminum receivers — Mil-spec strength without the extra weight. Why it matters: This rifle takes knocks in a truck rack or ATV scabbard and keeps running.
- 15-inch M-LOK handguard — Full-length rail space for lights, lasers, or bipods. Why it matters: Mount a Streamlight and a Harris bipod without losing zero or adding bulk.
- Magpul MOE stock and grip — Ergonomic, durable, and easy to clean. Why it matters: No sharp edges or plastic that cracks in cold weather—just solid function.
Who It’s For
This rifle is for ranchers, rural workers, and hunters who need a .308 that pulls double duty—varmint control in the pasture and paper punching at the range. It’s not a safe queen; it’s a tool you grab when a coyote hits the chicken coop or you need to drop a feral hog at 200 yards. Utility buyers who want reliability without the Gucci price tag will appreciate the Diamondback DB10 .308 Win 16″ M-LOK Rifle.
Pros & Cons
- Pros: Lightweight for a .308 AR (8.5 lbs), accurate 1:10 twist barrel, Magpul furniture included, M-LOK handguard for accessories, affordable price under $1,000.
- Cons: Trigger is a standard mil-spec—passable but not match-grade. Aftermarket triggers from Timney or Geissele are a common upgrade. Also, the 16-inch barrel limits muzzle velocity with heavy .308 loads compared to 18- or 20-inch barrels.
