Diamondback DB15 — .300 Blackout, 10" Barrel, 28+1, FDE, Carbon Lower, 9" M-LOK® Handguard, Black Padded Buffer Tube, Magpul® Grip (Model DB1915B061 | UPC 810035755611)
Compact power meets modern reliability. The Diamondback DB15 in .300 Blackout pairs a maneuverable 10" barrel with a durable carbon composite lower and slim 9" M-LOK® free-float handguard, all dressed in Flat Dark Earth (FDE) with black accents. A black padded buffer tube softens shouldering on braced or bare-tube setups, while the Magpul® pistol grip delivers confident control for fast strings and one-hand manipulations. Chambered in .300 BLK and configured at 28+1 capacity, this DB15 is built for range work, vehicle carry (where lawful), and compact hunting/utility roles that benefit from short-barrel efficiency.
Why This DB15 .300 BLK Stands Out
Purpose-Built 10" Barrel: Optimized for .300 Blackout ballistics—excellent energy retention in a short package, with subsonic/supersonic flexibility.
Free-Float Precision: 9" M-LOK® handguard provides ample slot real estate for white lights, hand stops, sling mounts, and IR/laser accessories without affecting barrel harmonics.
Lightweight, Tough Lower: Carbon composite lower reduces weight while maintaining structural strength for hard use and travel.
Control & Comfort: Black padded buffer tube improves cheek contact; Magpul® grip enhances wrist angle and traction in wet or gloved conditions.
Clean Two-Tone Aesthetic: FDE furniture/upper with black hardware for a modern, understated look that hides wear and grime.
Performance You Can Feel
Soft Shooting with Subsonics: Pairing .300 BLK with an appropriate gas system helps tame recoil for faster follow-ups.
Accessory-Ready: M-LOK slots at the 3/6/9 o’clock let you stage a light, pressure pad, and hand stop exactly where you want them.
Compact Handling: 10" barrel + slim rail = quick target transitions in dense brush, barricade work, and tight indoor lanes.

Ideal Use Cases
Range & Training: Run subsonic drills, barrier transitions, and low-light setups with a light and sling.
Hunting/Utility: Compact handling in blinds or vehicles; .300 BLK offers efficient performance with proper bullet selection.
Home/Property (where lawful): Add a white light and red dot for a modern, capable defensive configuration.
Optics & Accessory Suggestions
Low-Power Variable (LPVO) 1-6x / 1-8x for do-all versatility, or a micro red dot + flip-to-side magnifier for fast CQB with extended-range ID.
Muzzle Device: Brake or flash hider depending on priorities; ensure 5/8x24 threading compatibility.
Sling: Two-point on M-LOK QD cups or direct-mount.
Light: 1,000+ lumen weapon light at 10:30/1:30 with a remote switch on the rail.
Basic Setup & Care
Break-In: Run quality brass ammo; verify function with your chosen subsonic/supersonic loads.
Gas & Lube: Keep the BCG lightly lubed; confirm bolt lock-back with your primary ammo.
Fastener Check: Re-torque optic/ring and M-LOK fasteners after first range day.
Cleaning: Bore, chamber, and BCG rails after sessions; wipe the handguard and buffer tube as needed.
Compliance & Safety
Know the Law: Capacity, barrel length, braces, and suppressor rules vary. Confirm local/state/federal regulations before purchase or modification.
Safe Handling: Always transport unloaded; keep ammo type clearly separated (subsonic vs. supersonic).
Suppressor Use: If adding a suppressor, verify thread pitch and alignment; tune gas if necessary.
