Daniel Defense DD5 V4 7.62×51 Rifle 18 inch Brown

Product Description

The Daniel Defense DD5 V4 is a semi-automatic rifle built for shooters who demand accuracy and reliability. This 308 Winchester configuration pairs a heavy, cold-hammer-forged 18-inch barrel with Daniel Defense’s proven large-frame platform. Whether you’re shooting factory ammo or handloads, this rifle delivers consistent performance.

Additionally, every Daniel Defense firearm is hand-assembled, quality tested, and test-fired before shipment. The DD5 V4 features a user-adjustable gas block that lets you tune the action for different 7.62x51mm loads and suppressor use. This flexibility means fewer malfunctions and better control across ammunition varieties.

Furthermore, the DD5 Rail 15.0 free-float M-LOK handguard isolates the barrel from accessory pressure. Result: your zero stays rock-solid, shot after shot. The Mil-Spec single-stage trigger delivers a reliable, consistent pull for range and field work alike.

Magazine Compatibility and Modern Ergonomics

The rifle accepts readily available SR-25-pattern magazines, including Magpul PMAG 20 LR/SR units. This means ammunition resupply and accessory selection are straightforward and affordable. The large-frame DD5 platform is purpose-built for the 308 Winchester round.

Frequently Asked Questions

Q: What ammunition performs best in the DD5 V4’s 308 Winchester chamber?

A: The DD5 V4 is chambered for both 7.62x51mm NATO and commercial 308 Winchester ammunition. The user-adjustable gas block lets you dial in reliable cycling with light target loads, heavy hunting rounds, or even suppressed subsonic ammo. Always start with factory-tested loads matching your rifle’s manual.

Q: What optics and accessories mount to the DD5 Rail 15.0 M-LOK handguard?

A: The M-LOK handguard accepts any M-LOK-compatible accessories: lights, lasers, grips, slings, and bipods. For optics, the top Picatinny rail accepts standard AR-pattern red dots, magnified scopes, and backup sights. Magpul PMAG 20 LR/SR magazines load and run smoothly in the SR-25 magazine well.

Q: Does the DD5 V4 come with iron sights or do I need to buy them separately?

A: The DD5 V4 ships with the rifle, trigger, gas block, and handguard—no iron sights or optics are included. This gives you freedom to add sights and optics that match your specific mission. Many shooters pair it with a quality scope or red dot mounted to the upper receiver rail.

Q: What is included in the box, and what is Western Sport’s return or warranty policy?

A: Each DD5 V4 arrives ready to fire with all factory-assembled components. Daniel Defense stands behind every rifle with a manufacturer warranty. Contact Western Sport’s customer service team to confirm what’s included and review our return policy before checkout.

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.
