5.56 NATO Performance in a Proven AR-15 Platform
At the core of this rifle is a 5.56x45mm NATO chamber, giving you maximum flexibility with both 5.56 and .223 Remington loads (always follow manufacturer guidance and ammo specs):
5.56 NATO chambering for defensive, training, and competition loads
Semi-automatic, direct-impingement AR-15 platform for familiar operation and easy maintenance
30+1 capacity with a standard detachable magazine, compatible with most AR-15 pattern mags
Whether you’re zeroing optics, running drills, or shooting recreationally, this DB15 delivers the performance you expect from a modern 5.56 carbine.
16" Barrel – Balanced Length for Accuracy & Maneuverability
The 16-inch barrel hits the sweet spot for a general-purpose AR:
Optimal combination of velocity, accuracy, and handling
Legal rifle barrel length in most jurisdictions without the need for special paperwork
Threaded muzzle (commonly AR-standard) from the factory, ready for a flash hider, compensator, or muzzle brake where legal
This configuration makes the DB15 a versatile choice for range use, drills, home defense, and field carry.
M-LOK Handguard – Lightweight, Modular & Mission-Ready
One of the defining features of this model is its M-LOK compatible handguard:
Slim, free-float style handguard helps reduce weight and improves balance
M-LOK slots allow you to mount lights, lasers, vertical grips, hand stops, and other accessories exactly where you want them
Keeps the rifle’s profile trim and comfortable for extended shooting sessions
The result is a modern, modular front end that’s easy to customize for any mission or shooting style.
Green/Gold Finish – Standout Style with a Tactical Edge
The green and gold color combo on this DB15 makes it a real standout—without sacrificing practicality:
Green base finish provides a subdued, field-ready tone
Gold accents add a unique, custom-style appearance straight from the factory
Ideal for shooters who want something more eye-catching than plain black, but still tactical and professional
If you appreciate custom Cerakote-style looks but want them factory-applied, this green/gold DB15 is an excellent choice.
AR-15 Ergonomics – Familiar, Comfortable & Upgradable
Built on the standard AR-15 ergonomic footprint, this DB15 ensures you feel right at home:
Adjustable buttstock so you can dial in length of pull for different shooters or shooting positions
Standard AR pistol grip for familiarity and easy upgrades to your preferred grip style
Ambidextrous-friendly layout (mag release and safety on the usual side but compatible with many aftermarket ambi upgrades)
Picatinny top rail on the upper receiver and handguard (configuration varies) for mounting optics, backup iron sights, and accessories
Since it follows common AR-15 dimensions, you can customize the rifle over time with endless aftermarket stocks, grips, triggers, and optics.
Optics-Ready & Accessory-Friendly
The DB15 ML 16" 5.56 is designed to be optics-ready, giving you flexibility in your sighting system:
Flat-top upper receiver ready for red dots, LPVOs, prism scopes, or traditional optics
M-LOK handguard and top rail allow for BUIS (backup iron sights), offset optics, and accessories
Easy to configure as a home-defense rifle, training carbine, or competition-ready setup simply by changing your optic and accessories
For most shooters, pairing this rifle with a quality red dot or low-power variable optic will unlock its full potential.
Ideal Uses – Range, Home Defense, Training & More
Thanks to its combination of 16" barrel, 5.56 NATO chamber, M-LOK handguard, and AR ergonomics, the DB175AK801 is well-suited for:
Range and recreational shooting – fun, accurate, and comfortable to shoot for extended sessions
Home and personal defense – reliable AR platform with modern accessory mounting for lights and optics
Training and classes – a great workhorse rifle for learning or teaching AR operation and marksmanship
Competition entry – solid starting point for 3-gun, carbine matches, or practical rifle competitions
Whether you’re a first-time AR owner or adding another rifle to your collection, this DB15 configuration delivers both function and flair.
