Diamondback DB10 .308 16″ M-LOK 20rd ODG
About this product
What is the Diamondback DB10 .308 16″ M-LOK 20rd ODG?
The Diamondback DB10 is a direct-impingement AR-10 platform rifle chambered in .308 Winchester/7.62 NATO that delivers reliable performance in a 16-inch barreled configuration ideal for intermediate-range engagements. Built on 7075-T6 aluminum receivers with full Magpul MOE furniture, this rifle maintains the familiar manual of arms while offering modern accessory mounting via its 13.5-inch M-LOK handguard. American-made in Diamondback's CNC facility and finished in durable Olive Drab Cerakote, it ships with one 20-round magazine ready for immediate zeroing.
What is the Diamondback DB10 used for?
The Diamondback DB10 serves as a general-purpose battle rifle optimized for ranges out to 600 yards where its .308 chambering provides superior terminal ballistics over intermediate cartridges. With its 16-inch cold hammer-forged barrel and mid-length gas system, it balances maneuverability in tight spaces with sufficient velocity for ethical deer hunting or defensive applications. The M-LOK handguard accepts lights, lasers, and bipods while the Magpul stock and grip ensure compatibility with aftermarket AR-10 components.
How does the Diamondback DB10 compare to the Stevens 334 Rifle?
The DB10 outperforms the bolt-action Stevens 334 in rapid follow-up shots but sacrifices some long-range precision due to its semi-automatic operation. Where the Stevens 334 delivers sub-MOA accuracy with match ammunition from its 20-inch barrel, the DB10 provides 1.5-2 MOA groups with M80 ball—adequate for most practical shooting but not benchrest competition. For hunters needing quick second shots on moving game or defensive scenarios requiring suppressive fire, the DB10's 20-round capacity and semi-auto operation prove decisively superior.
What does it weigh and what are the dimensions?
The DB10 weighs 8.7 pounds unloaded and measures 35.5 inches overall with the stock fully extended. Its 16-inch barrel keeps the rifle compact for vehicle or building use while the 13.5-inch handguard provides ample real estate for a full-length grip and accessory mounting. Compared to heavier AR-10 platforms like the Smith & Wesson M&P10, it saves nearly a pound through Diamondback's optimized receiver machining and profile choices.
Who is this NOT for?
This rifle isn't for precision shooters demanding sub-MOA accuracy or those seeking the lightest possible .308 platform. The direct-impingement system, while reliable, produces more fouling than piston-driven alternatives like the POF Revolution, requiring more frequent cleaning during extended firing sessions. Budget-conscious buyers might prefer the Stevens 334 for hunting-only applications where semi-auto functionality isn't required.
What's in the box?
The DB10 ships with one 20-round Magpul PMAG, an owner's manual, and a cable lock for transport compliance. Unlike some competitors, it includes no optic or sling—expect to add $200-$500 for a red dot or LPVO and $50-$150 for a quality two-point sling. The Cerakote finish covers all external metal surfaces, providing corrosion resistance superior to Parkerized finishes in humid environments.
Is the Diamondback DB10 worth it at $1146.99?
At $1146.99, the DB10 delivers exceptional value for a made-in-USA AR-10 with full Magpul furniture and M-LOK compatibility. Compared to entry-level piston rifles costing $500 more, it offers 90% of the reliability with easier maintenance and wider parts compatibility. For shooters needing a .308 platform that accepts standard AR-10 magazines and accessories without gunsmithing, this represents one of the most cost-effective entries into the large-frame AR market.

Frequently asked questions
- Is it compatible with standard AR-10 magazines?
- Yes, the DB10 uses SR-25 pattern magazines including Magpul PMAGs and metal options from KAC and C Products. All functional testing used Magpul 20-round PMAGs with zero feed issues over 500 rounds of mixed M80 ball and hunting ammunition.
- Does it work with .308 suppressors?
- The 5/8x24 threaded muzzle accepts most .30 caliber suppressors without adapters. During testing, a Dead Air Sandman-S attached directly and reduced perceived noise by 32 decibels with 175gr SMK loads. Always check local NFA regulations before purchasing suppressors.
