Daniel Defense DD4 V7 SLW Rifle, 5.56 NATO, 14.5″ Barrel

Product Description

The Daniel Defense DD4 V7 SLW Rifle in this configuration is a semi-automatic 5.56 NATO rifle with a 14.5" Lightweight profile barrel, 1:7 twist, mid-length gas system on a low profile gas block, a Daniel Defense DD4 13.5 M-LOK rail and an ASR flash hider pinned and welded to the muzzle.

The muzzle device is what sets this SKU apart. ASR is a quick-attach mounting standard, and having that device pinned and welded from the factory means the rifle arrives ready for a matching suppressor without a threaded muzzle to fuss over — while the permanent attachment keeps the 14.5" barrel assembly over 16 inches, so the firearm remains an ordinary rifle with no NFA paperwork. If a can is in your plans, this is the version of the V7 SLW to look atfirst. Call 817-393-4000 and we will confirm exactly which suppressors and mounts this device pairs with before you commit.

Underneath, this is Daniel Defense’s fast-handling carbine. The Lightweight barrel profile strips mass from ahead of the gas block, the free-float 13.5-inch M-LOK rail keeps the balance point near the receiver, and mid-length gas lowers port pressure relative to a carbine system for a smoother impulse. It is built to be carried and shot standing rather than to soak up heat from long support-position strings.

Choosing between the Xeno and ASR versions

Daniel Defense builds this rifle with two different pinned and welded muzzle devices, and the choice is not cosmetic. The Xeno SKU and this ASR SKU use different suppressor mounting standards, and because the device is permanent you are choosing a mounting ecosystem for the life of the rifle. Decide which suppressor family you want to live in first, then pick the SKU. If you already own a can, tell us what it is when you call and we will point you at the right one. Our suppressor and muzzle device pages are the places to browse for the rest of that build.

What the 14.5-inch mid-length does well

This length is the sweet spot for a general-purpose 5.56 carbine that still measures as a rifle. Compared with a 16" mid-length you gain a lighter muzzle and slightly quicker handling; compared with a 10.3" or 11.5" short-barrelled rifle you keep meaningful velocity and avoid the NFA process entirely. See the rest of our Daniel Defense rifles to compare lengths.

Frequently Asked Questions

Q: What is the ASR flash hider on this rifle for?

A: ASR is a quick-attach suppressor mounting standard, so the pinned and welded ASR flash hider makes this rifle a ready host for a matching can. Because the device is permanent, it also keeps the 14.5-inch barrel assembly over 16 inches. Call 817-393-4000 and we will confirm exactly which suppressors and mounts it pairs with.

Q: How is this SKU different from the Xeno version of the DD4 V7 SLW?

A: Only the muzzle device, and it matters. This SKU has a pinned and welded ASR flash hider; the sibling SKU has a pinned and welded Dead Air Xeno flash hider. They belong to different suppressor mounting standards, and because both are permanent, the choice commits the rifle to one ecosystem.

Q: Does the permanent muzzle device make this an NFA firearm?

A: No — it does the opposite. Pinning and welding the flash hider makes barrel and device one unit measuring more than 16 inches, which keeps the rifle out of the NFA short-barrelled rifle category. There is no tax stamp involved; it transfers like any other rifle through an FFL.

Q: Why choose a Lightweight profile barrel?

A: Weight and handling. Removing steel ahead of the gas block makes the rifle quicker to point and easier to carry, which matters when a light, laser and optic are already adding mass. The trade-off is less thermal mass, so the barrel heats faster in long strings than a Government or S2W profile.

Q: What does the mid-length gas system change at 14.5 inches?

A: It lowers the pressure at the gas port and lengthens dwell compared with a carbine system, which softens the recoil impulse and reduces wear on the bolt and carrier. You feel it as a rifle that tracks flatter and settles faster between shots.

Q: Can this rifle ship directly to me?

A: No. It is serialized and must be transferred through a licensed FFL. Western Sport in Roanoke, Texas holds an FFL and an SOT and can complete the transfer in store or ship to a dealer near you. Call 817-393-4000 and we will make the arrangements.
