Daniel Defense DDM4 ISR SBR, .300 Blackout, Black, No Magazine

Product Description

The Daniel Defense DDM4 ISR, part 02-103-02041-067, is an integrally suppressed NFA short-barrelled rifle in .300 Blackout on the AR-15/M16 platform, finished in black and supplied by Daniel Defense without a magazine.

Daniel Defense tracks this as a separate SKU purely for what is left out; the firearm is built the same way on the same line. Buyers choose it when capacity is regulated where they live and the magazine must come from a local source. Order the standard black DDM4 ISR configuration instead if you do not need it. Capacity rules are jurisdiction-specific and subject to change, so confirm what applies where you are. Call 817-393-4000 for help sourcing a compliant magazine, or see our magazine selection.

NFA-Regulated Firearm

The DDM4 ISR is integrally suppressed, which makes it an NFA-regulated firearm on more than one count. A BATFE tax stamp and an approved transfer are required, and the transfer must go through a dealer holding a Special Occupational Tax stamp. Western Sport is an SOT and a licensed FFL, and this firearm transfers through a licensed FFL. We state no wait times or tax amounts and will not speculate about how the suppressor portion is registered.

Frequently Asked Questions

Q: What does ISR mean on this Daniel Defense rifle?

A: ISR is Daniel Defense’s Integrally Suppressed Rifle configuration, meaning the suppressor is part of the firearm rather than an accessory threaded on afterwards. That is why it is an NFA-regulated firearm on more than one count and why the transfer runs through an SOT dealer.

Q: Why is the DDM4 ISR regulated on more than one count?

A: Because it is both a short-barrelled rifle and an integrally suppressed firearm. Either characteristic alone brings a firearm under the National Firearms Act. A BATFE tax stamp and an approved transfer through a Special Occupational Tax stamp holder are required, and Western Sport is an SOT.

Q: How is the suppressor portion registered?

A: We will not speculate on that. What we can tell you is that the DDM4 ISR is an NFA-regulated firearm and that Western Sport, as a licensed FFL and SOT, handles the transfer. Call 817-393-4000 and we will explain the steps that involve us.

Q: What does the no-magazine ISR configuration change?

A: Only that no magazine is packed with the firearm. Daniel Defense builds this part number for buyers whose jurisdictions regulate magazine capacity, where a compliant magazine is supplied locally instead. Everything mechanical about the rifle, the suppressor included, matches the standard configuration exactly.

Q: What magazines will the ISR accept?

A: It is an AR-15/M16 pattern firearm, so magazines for that pattern are the starting point, with capacity governed by your own state and locality. Verify the rules currently in force where you live, then call 817-393-4000 and we will help you choose a compliant magazine.

Q: Can you confirm the barrel length and weight?

A: By phone, yes. We will not publish a barrel length or weight for this part number that we have not verified against the exact SKU, because a wrong number on an NFA firearm is a real problem. Call 817-393-4000 and we will confirm it for you.
