Daniel Defense DDM4 MK18 SBR, 5.56 NATO, FDE, No Magazine

Product Description

The Daniel Defense DDM4 MK18 SBR, part 02-088-17024-067, is an NFA short-barrelled rifle in 5.56mm NATO with a 10.3-inch Government profile barrel and MK18 RIS II quad rail in Flat Dark Earth, and it leaves Daniel Defense without a magazine.

This is a factory part number, not a stripped build. The firearm matches the standard version exactly; the magazine is left out so buyers in capacity-regulated jurisdictions can have a compliant one supplied at transfer. Order the standard FDE MK18 SBR instead if you do not need it. We do not advise on any jurisdiction’s law: confirm the magazine rules applicable where the firearm will be kept. Send us a message for help sourcing a compliant magazine, or see our magazine selection.

Frequently Asked Questions

Q: How does the FDE MK18 SBR differ from the black one?

A: Finish, and that is all. Both are the same 10.3-inch MK18 short-barrelled rifle in 5.56mm NATO with the RIS II quad rail and carbine gas system; this part number is finished in Flat Dark Earth. Send us a message if you want them compared side by side.

Q: Why does this SKU arrive without a magazine?

A: Daniel Defense builds the configuration for buyers whose jurisdictions regulate magazine capacity. The rifle itself is identical to the standard build.

Q: Does the FDE finish extend to the rail?

A: The Flat Dark Earth finish is what distinguishes this part number, covering the rifle as Daniel Defense configures it. If you need to know precisely which components are coated and which are not before you commit, send us a message and we will go over it.

Q: Is a tax stamp needed for the FDE version too?

A: Yes, exactly as for any other finish. The 10.3-inch barrel makes this an NFA short-barrelled rifle requiring a BATFE tax stamp and an approved transfer through a Special Occupational Tax stamp holder. Western Sport is an SOT. We quote no wait times or tax amounts.

Q: How long is it with the stock collapsed?

A: Overall length runs from 26 3/4 inches to 29 7/8 inches with the muzzle device fitted, depending on where the stock sits. That collapsed figure is a large part of why the MK18 pattern is chosen for vehicle and close-quarters use in the first place.

Q: Where do I get a magazine that suits my jurisdiction?

A: From us or from a dealer local to you.
