Key Features
- A3 Flat Top Upper Receiver — This gives you a full Picatinny rail for mounting optics, red dots, or magnifiers without needing an adapter. It’s the standard for modern .308 ARs.
- 13.5-inch M-LOK Handguard — The free-float design keeps barrel harmonics consistent for better accuracy, and M-LOK slots let you attach bipods, lights, or sling mounts exactly where you need them.
- SB Tactical SBA3 Brace — Adjustable like a carbine stock, but legally a pistol brace. It gives you a solid cheek weld and a clean look, and it’s easy to collapse for storage or transport.
- Magpul MOE K Grip — The more vertical angle reduces wrist fatigue during long sits, and the rubber overmold keeps your hand planted even in wet weather.
- Magpul Gen M3 20rd PMAG — Includes one of the most reliable .308 magazines on the market. The Gen M3 has improved impact resistance and a dust cover that stays attached.
Who It’s For
This rifle is for the hunter who wants a lightweight .308 that’s easy to carry up a ridge or through thick timber. The 13.5-inch barrel and brace make it a natural choice for truck guns, saddle scabbards, or anyone who needs a compact .308 for hogs, deer, or black bear. It’s also a solid pick for shooters who want to build a suppressed setup later — the short barrel keeps overall length manageable with a can attached.
DIA DB1222C062 Pros & Cons
- Pro: Lightweight at 7.8 lbs — you can carry this all day without feeling it.
- Pro: Factory-built reliability — Diamondback assembles these in-house, so you don’t have to worry about headspace or gas system tuning.
- Con: The 13.5-inch barrel means some velocity loss compared to a 16-inch or 20-inch .308 — you’ll lose about 100–150 fps with most loads, so plan your shots inside 400 yards.

FAQ
What is the barrel twist rate on the Diamondback DB10?
The DB10 uses a 1:10 twist rate, which stabilizes most .308 bullets from 150 to 175 grains well. According to Diamondback specs, it’s button-rifled for consistent accuracy.
Can I use standard AR-10 magazines in this rifle?
Yes, the DB10 accepts DPMS-pattern .308 magazines. The included Magpul Gen M3 PMAG is a DPMS-spec mag, so any DPMS-compatible magazine will work.
Is the SB Tactical SBA3 brace legal to shoulder?
As of the latest ATF rulings (as of early 2025), pistol braces like the SBA3 are considered “rifle stocks” under the 2024 rule. However, this rifle is sold as a pistol with a brace, and current litigation may change the status. Check your local laws before purchasing.
Does the DB10 come with a muzzle device?
Yes, it includes an A2 flash hider. It’s pinned and welded? No — it’s threaded 5/8×24, so you can swap it easily for a suppressor or brake.
