Diamondback DB105AC221 DB10 308 Win 20+1 16″ FDE Chromoly Barrel, Black Rec/M-Lok Handguard, FDE Magpul Carbine Stock/K2 Grip

The Diamondback DB105AC221 DB10 .308 Win 20+1 16″ FDE Chromoly Barrel, Black Rec/M-Lok Handguard, FDE Magpul Carbine Stock/K2 Grip is a battle-ready large-frame AR that gives your family the confidence to reach out with precision. Chambered in .308 Winchester, this DB10 cycles smoothly using the proven gas-impingement system, and the 16-inch chromoly barrel keeps the package handy without sacrificing terminal performance. The flat dark earth Magpul furniture (carbine stock and K2 grip) fits shooters of all hand sizes, while the black M-Lok handguard lets you mount lights, grips, or bipods exactly where your support hand wants them. Per manufacturer specs, this rifle is built entirely in Diamondback’s USA CNC facility, so you know every component meets a tight tolerance.

Key Features

• 16″ Chromoly Barrel with FDE Finish – Why it matters: The shorter barrel keeps the rifle maneuverable in tight spaces or while hunting from a blind, and the flat dark earth finish resists corrosion and glare in the field.
• M-Lok Handguard (Black) – Why it matters: You can attach a bipod, foregrip, or light without adding weight or bulk, and the slim profile fits smaller hands comfortably for new shooters.
• Magpul MOE Carbine Stock & K2 Grip (FDE) – Why it matters: The K2 grip has a more vertical angle that reduces wrist fatigue, and the carbine stock adjusts to six positions so teens and adults can both get a proper length of pull.
• 20-Round Magazine – Why it matters: You get enough capacity for a full magazine at the range or multiple follow-up shots on a hog or coyote without constant reloading.
• USA-Made Gas-Impingement System – Why it matters: Diamondback machines the bolt carrier group and upper receiver in-house, so the rifle cycles reliably with a wide range of .308 ammunition.

Who It’s For

This DB10 is built for families who want a .308 semi-auto that won’t beat up beginners. The adjustable stock and ergonomic K2 grip make it easy to teach proper stance and cheek weld. It’s also ideal for the hunter who needs one rifle for deer, hogs, and long-range steel, and for the shooter who wants a US-made AR-10 pattern without the boutique price tag.

Pros & Cons

• Pro: Reliable direct-impingement action that’s easy to clean and maintain.
• Pro: Lightweight 16-inch barrel keeps the overall rifle under 8.5 pounds.
• Pro: Factory-installed Magpul furniture saves you the cost of upgrading.
• Con: The carbine-length gas system can feel a bit sharper on recoil than a rifle-length system, but it’s still manageable for most shooters.
