Daniel Defense DDM4 V7 Pro 5.56mm NATO 18″ 1:7″ Bbl Gun Metal Grey Rifle – 02-128-09385-047
About this product
The Daniel Defense DDM4 V7 Pro is a premium AR-pattern rifle chambered in 5.56mm NATO/.223 Remington, built with an 18-inch, 1:7-twist barrel and finished in Daniel Defense's Gun Metal Grey Cerakote. It's part of Daniel Defense's V7 Pro Series, which pairs the company's own barrel, handguard, stock, and grip on one rifle rather than mixing in third-party furniture. This is the longer-barreled configuration in the V7 line, favoring a bit more velocity and sight radius over the shorter carbine-length V7 variants.
What is the DDM4 V7 Pro?
It's a semi-automatic, direct-impingement AR-15-pattern rifle built entirely with Daniel Defense components: their own free-float handguard, DD-branded pistol grip, and DD buttstock, on top of an 18-inch cold hammer-forged barrel with a 1:7 twist rate suited to a wide range of 5.56/.223 bullet weights. Daniel Defense builds its reputation on barrel quality and handguard rigidity, and the Pro Series is the tier where all the furniture matches that same in-house standard rather than mixing in outside parts.
What is it used for?
The 18-inch barrel length makes this rifle well suited to home defense, general-purpose range use, and hunting varmints or predators within the 5.56/.223 cartridge's effective range. The longer barrel and 1:7 twist also make it a solid platform for stretching out to mid-range precision shooting with heavier match-grade bullets, more so than a shorter 14.5 or 16-inch carbine-length V7.
How does it compare to a 16-inch AR-15?
The extra barrel length adds muzzle velocity and a longer sight radius, both useful at distance, at the cost of a longer, front-heavier rifle that's less handy in tight spaces like a vehicle or hallway. If your priority is maneuverability, a 16-inch carbine-length DDM4 is the better fit; if you want more reach and stability for mid-range shooting, this 18-inch configuration is the stronger choice.
What fits it?
It accepts standard AR-15/M4 magazines, and the Daniel Defense free-float handguard uses their M-LOK attachment system for lights, grips, and bipods. Standard AR-pattern optics mounts fit the flat-top upper receiver rail. Because the furniture is proprietary Daniel Defense, swapping the handguard or stock for a different brand is possible but means giving up the matched-component look and feel this Pro Series is sold on.
Is it worth $1,788?
For buyers who want a cold hammer-forged Daniel Defense barrel and matching in-house furniture without assembling it themselves from separate parts, yes — DD barrels carry a strong reputation for accuracy and durability that justifies the premium over a budget AR-15. If you're comfortable building or buying a rifle with mixed third-party components, you can spend less and still get a reliable 5.56 rifle; you're paying here for the fully matched, single-manufacturer build quality.
Does it work in California?
Rifles ship to your licensed FFL with the standard 10-day wait, DROS, and FSC — there's no handgun roster involved. California's assault weapon law restricts specific features on semi-auto rifles with detachable magazines; confirm this exact configuration is featureless or otherwise compliant before your build leaves the shop, and any magazine sold with this rifle to California buyers is capped at 10 rounds regardless of the 32-round factory magazine noted for this model. Full detail on our California gun laws page. If you also want a shorter, more compact 5.56 rifle for the safe, our M1A SOCOM 16 is a heavier-caliber alternative worth comparing.
FFL transfer required
This item is a firearm and ships only to a licensed FFL dealer, never to a home address. At checkout, enter your preferred dealer as the shipping address, or leave it blank and we will assign a licensed dealer near you at no extra cost. You complete the background check and paperwork with the dealer when you pick up.
California buyers: handguns must be on the California roster for delivery to a California FFL, a Firearm Safety Certificate (FSC) and DROS are handled at the dealer, and the 10-day waiting period applies. Out-of-state buyers receive the firearm through their own local FFL under their state's rules.

Frequently asked questions
- What twist rate does this barrel use and why does it matter?
- It's a 1:7 twist, which stabilizes a wide range of 5.56/.223 bullet weights including heavier match bullets, making it more versatile than slower twist rates common on lighter varmint-focused barrels.
- Does it come with iron sights?
- The V7 Pro Series typically ships without iron sights, leaving the flat-top rail open for the optic of your choice; confirm with this listing if sights are included.
- Is the handguard free-float?
- Yes, Daniel Defense's V7 handguards are free-floated, meaning the handguard does not contact the barrel, which helps accuracy by keeping outside pressure off the barrel.
- Can I attach a suppressor to this rifle?
- The barrel needs to be threaded for that; confirm the muzzle device and thread pitch on this specific listing before buying a suppressor for it.
