Daniel Defense DD5 V4, Semi-automatic Rifle, 308 Winchester/7.62 NATO, 18″ Barrel, 1:10″ Twist, Black

Product Description

The Daniel Defense DD5 V4 is a semi-automatic rifle built on the proven large-frame DD5 platform in 7.62x51mm NATO/.308 Winchester. This 18″ barrel configuration strikes the balance between velocity and handling, making it ideal for precision shooters who demand reliability in competition or field use.

Every Daniel Defense firearm is hand-assembled, quality assurance tested, and test-fired before shipment. The DD5 V4 combines a Mil-Spec single-stage trigger with a user-adjustable gas block, letting you tune the action for different .308 loads and suppressor use without guessing.

Free-Float Precision & Modular Accessory Support

The DD5 Rail 15.0 free-float M-LOK handguard isolates the barrel from accessory pressure, maintaining a rock-solid zero shot to shot. Additionally, the rifle accepts SR-25-pattern magazines—including the popular Magpul PMAG 20 LR/SR—so you can source ammunition and accessories off any shelf.

Frequently Asked Questions

Q: What ammunition performs best in the Daniel Defense DD5 V4, and how does the adjustable gas block help?

A: The DD5 V4 shoots both 7.62x51mm NATO and commercial .308 Winchester loads accurately. The user-adjustable gas block lets you tune the action for lighter hunting rounds or heavier match ammunition without over-gassing or short-stroking.

Q: What optics and accessories are compatible with the M-LOK handguard on this rifle?

A: The DD5 Rail 15.0 M-LOK handguard accepts any M-LOK-compatible light, sling, or rail panel. It also works with standard Picatinny optic mounts on the upper receiver—red dots, magnified scopes, and LPVOs all mount securely.

Q: Does the DD5 V4 accept standard AR-pattern components, and are there other DD5 variants in stock?

A: The DD5 V4 uses its own large-frame platform and accepts SR-25-pattern magazines, not standard AR mags. Check with our team for other DD5 configurations, or ask about how this 18″ barrel compares to longer or shorter options for your use case.

Q: What comes in the box with this rifle, and what’s the warranty coverage?

A: The DD5 V4 ships fully assembled and test-fired, ready to mount an optic and shoot. Daniel Defense rifles carry a lifetime warranty on defects—our team can walk you through registration and answer any coverage questions after purchase.

Q: What is the M-LOK handguard on this rifle?

A: Daniel Defense’s free-float M-LOK handguard lets you attach lights, lasers, and grips directly to the rail using the M-LOK slot system — no separate rail sections required. Additionally, the handguard floats independently of the barrel, so attachments don’t shift your zero. A continuous top rail provides a stable mounting surface for optics.
