Daniel Defense DD4 RIII S SBR, 5.56 NATO, 11.5″ Barrel, FDE, No Magazine

Product Description

The Daniel Defense DD4 RIII S, part 02-191-30095-067, is an NFA short-barrelled rifle in 5.56mm NATO with an 11.5-inch Government profile barrel, a low profile gas block under a RIS III 10.5 M-LOK rail in Flat Dark Earth, and it leaves the factory 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 DD4 RIII S rifle instead if you do not need it. Capacity restrictions differ by jurisdiction and get revised, so verify the rules currently in force where you live. Call 817-393-4000 for help sourcing a compliant magazine, or see our magazine selection.

Frequently Asked Questions

Q: Why choose the 11.5-inch DD4 RIII S over a 10.3-inch build?

A: The extra inch of barrel buys a little velocity and a slightly softer impulse while keeping the rifle short enough for vehicle and indoor work. It also puts more barrel under the 10.5-inch RIS III rail. Call 817-393-4000 if you want the two lengths compared directly.

Q: What does the no-magazine part number change mechanically?

A: Nothing at all. Barrel, gas system, rail, receivers and controls are the standard DD4 RIII S specification. Daniel Defense assigns a separate SKU only because no magazine is packed with it, which suits buyers whose jurisdictions regulate capacity and who source a magazine locally.

Q: Does the short-barrelled rifle classification still apply?

A: Yes, and the omitted magazine makes no difference to it. This is an NFA short-barrelled rifle needing a BATFE tax stamp and an approved transfer through a dealer holding a Special Occupational Tax stamp. Western Sport is an SOT. No wait times or tax amounts are quoted.

Q: What magazine should I plan to use with it?

A: The DD4 RIII S is an AR-15/M16 pattern firearm, so magazines made for that pattern are the starting point, and capacity is what your own jurisdiction governs. Check the current rules where you live, then call 817-393-4000 and we will help you choose a compliant magazine.

Q: What does the low profile gas block do for this build?

A: A low profile gas block sits under the free-floating RIS III rail instead of protruding through it, which keeps the handguard continuous and leaves the top rail clear for optics and night vision. It is the normal arrangement for a rail of this length.

Q: Is the RIS III rail M-LOK or Picatinny?

A: It is M-LOK on the sides and bottom with a continuous Picatinny rail along the top. Daniel Defense modelled RIS III on the RIS II two-piece handguard developed for SOCOM, swapping the quad Picatinny rail for M-LOK to cut weight while retaining M203 grenade-launcher mounting capability.
