Overview
The DIAMONDBACK OBSIDIAN targets shooters who want a balanced, adaptable 5.56 NATO platform without excess weight. At 6.60 pounds with a 16-inch barrel and a 30-round PMAG, it strikes a middle ground between compact maneuverability and long-range controllability. The ODG finish provides a subdued profile well suited to field and low-light environments.
Design and Components
Barrel, Finish, and Gas System
The 16-inch FDE nitride-finished barrel brings corrosion resistance and extended service life, while the mid-length gas system smooths recoil impulse compared to carbine-length systems. For shooters prioritizing follow-up shots and reduced wear on internal parts, the mid-length setup plus a Mil-Spec BCG is a sensible pairing—reliable and easy to maintain.
Handguard and Modularity
The 15-inch M-LOK handguard gives you real estate for lights, grips, and bipods without adding unnecessary bulk. M-LOK is a modern, low-profile interface that keeps accessories secure while allowing for quick changes. That length also provides sufficient hand placement options for shooters of different sizes and shooting styles.
Controls and Ergonomics
Ambidextrous controls increase the rifle’s utility for left- and right-handed shooters and make it more adaptable in dynamic shooting positions. The Magpul MOE K2 grip is a comfortable, proven option that speeds reload transitions and keeps hand fatigue down. The CTR stock offers solid cheek weld and a dependable locking system to maintain consistent zero when shouldering optics.
Performance and Use Cases
Chambered in 5.56 NATO, this rifle is optimized for low-recoil training, varmint and nuisance management, and defensive roles where follow-up shots and controllability matter. The 5.56 NATO round is widely available and balances terminal performance with low recoil—ideal for shooters who want to train more efficiently and apply those skills where needed. The 16-inch barrel preserves velocity for effective terminal ballistics at typical engagement distances while remaining compact enough for confined spaces.
Range and Duty Utility
For range work, the DIAMONDBACK OBSIDIAN will be forgiving and easy to shoot well, enabling fast drills and sustained practice. For duty or personal defense configurations, the rifle’s mid-length gas and nitride barrel help with heat management during extended strings, while the ambidextrous controls support rapid manipulation under stress.

Accessories, Reliability, and Upgrades
The included 30-round PMAG is a dependable baseline; it’s a quality magazine that many shooters trust for consistent feeding. From here you can configure optics, backup sights, or an illumination package on the M-LOK handguard. The Mil-Spec BCG ensures serviceability—replacement parts are widely available, and maintenance follows familiar AR-pattern procedures.
Customization Options
If you favor optics, the CTR stock keeps your cheek weld consistent with a mounted red dot or low-power variable optic. Swap grips, add ambidextrous magazine release upgrades, or fit a suppressor-ready muzzle device if you prioritize signature reduction—just maintain proper headspace and compliance with local laws.
Price and Value
At a price of $926.99, the DIAMONDBACK OBSIDIAN delivers a complete, out-of-the-box platform with quality furniture and a modern accessory interface. For shooters who want a ready-to-go rifle with room to evolve, that price point places it competitively against other semi-auto 5.56 options that require aftermarket upgrades to match the included components.
