Daniel Defense DDM4 V7 Pro Rifle, 5.56 NATO, 18″ Barrel, Cobalt, California Compliant

Product Description

The Daniel Defense DDM4 V7 Pro Rifle in Cobalt is a semi-automatic 5.56 NATO rifle with an 18" S2W heavy profile cold hammer forged barrel, rifle-length gas system on a low profile gas block, a Geissele Automatics Super Dynamic 3-Gun trigger, a Daniel Defense Muzzle Climb Mitigator and an MFR 15.0 M-LOK rail, built as Daniel Defense’s California Compliant SKU with a Magpul PMAG 10-round magazine.

This is the compliant twin of the standard Cobalt V7 Pro, and the rifle itself is unchanged: same 18" barrel, same gas length, same factory-fitted match trigger. If you are shopping from a jurisdiction with a compliance requirement, this is the part number that lets you own the same competition rifle everyone else is buying.

What that rifle does well is stay still. Rifle-length gas on an 18" barrel gives the longest dwell and lowest port pressure in the AR-15, so the bolt unlocks later and the impulse is flatter than any carbine or mid-length build. The Muzzle Climb Mitigator vents gas through calibrated ports specifically to counter muzzle rise. The Geissele trigger has a light, short pull and a fast reset. At 7.40 lbs, the weight works with you across a stage rather than against you.

California Compliant configuration

Daniel Defense catalogues this as its California Compliant V7 Pro and configures it with a Magpul PMAG 10-round magazine. Compliance requirements are revised from time to time and are applied differently by locality, so nothing on this page is a statement that the rifle is legal where you are. Confirm the current requirements for your own jurisdiction before ordering, then call 817-393-4000 and we will confirm the configuration of this exact SKU.

Compliant SKU or standard SKU?

Daniel Defense builds the Cobalt V7 Pro both ways. The standard part number is configured with a DD magazine; this one is the compliant configuration. Buy the compliant SKU only if you need it — if you do not, the standard rifle is the simpler purchase. Either way, compare the Daniel Defense rifle range, look at optics sized for an 18-inch rifle, and see our scope mounts.

Frequently Asked Questions

Q: How does this Cobalt V7 Pro differ from the standard Cobalt V7 Pro?

A: Only in configuration class. This part number is Daniel Defense’s California Compliant build, configured with a Magpul PMAG 10-round magazine; the standard part number is configured with a DD magazine. The 18-inch S2W barrel, rifle-length gas system, Geissele trigger and MFR 15.0 rail are the same on both.

Q: Why does an 18-inch barrel suit a competition rifle?

A: It adds velocity over a carbine, carries enough mass in the S2W profile to resist heat-related point-of-impact shift, and is the shortest barrel that comfortably takes a rifle-length gas system. That gas length is what gives the rifle its flat impulse and predictable tracking.

Q: What is the Geissele Super Dynamic 3-Gun trigger like?

A: Light and short, with a quick reset — built for shooters firing fast, accurate strings. Daniel Defense fits it at the factory on the V7 Pro, so the most common first upgrade on a competition AR is already done when the rifle reaches you.

Q: Is the Cobalt V7 Pro legal in California?

A: We cannot tell you that. Daniel Defense builds this SKU as a California Compliant configuration, but the requirements change and are read differently from one locality to the next. Verify what currently applies at your address with a competent source, and call 817-393-4000 with questions about this SKU.

Q: How much does the rifle weigh and how long is it?

A: 7.40 lbs, with an overall length of 34 3/4 to 37 7/8 inches including the muzzle device across the stock’s adjustment range. That is about a pound heavier and three inches longer than a 16-inch V7, which is the trade for the velocity and stability.

Q: Can this be shipped to my house?

A: No. Firearms transfer through a licensed FFL only. Western Sport in Roanoke, Texas holds an FFL and an SOT and can complete the transfer in store, or ship the rifle to a dealer nearer you. Call 817-393-4000 and we will make the arrangements.
