DANIEL DEFENSE ISR (Deep Woods Cerakote)

Product Description

The DANIEL DEFENSE ISR (Deep Woods Cerakote) is a purpose-built .300 AAC Blackout rifle engineered for shooters who demand suppressed performance straight out of the box. Its fully integral stainless steel suppressor is pinned and welded to a 9″ fluted Cold Hammer Forged barrel, extending total length to 16″ so you get suppressed shooting without a separate silencer to attach or re-zero.

This rifle ships ready to fire suppressed. The pistol-length gas system and 1:8 twist rate handle both subsonic and supersonic .300 AAC Blackout loads with greatly reduced muzzle blast and flash. Daniel Defense hand-assembles, quality assurance tests, and test fires every firearm before shipment.

The Daniel Defense MFR XL 15.0 free-float KeyMod handguard gives you a continuous top Picatinny rail and plenty of real estate for lights, lasers, and vertical foregrips. This configuration is built for hunters, precision shooters, and operators seeking a compact, quiet platform.

Specifications

This rifle’s suppressor is permanently pinned and welded to its barrel, extending the overall barrel length to the NFA-required 16 inches — so the rifle itself is NOT classified as a Short-Barreled Rifle and needs no SBR paperwork. The integral suppressor itself, however, IS a Title II item regulated under the National Firearms Act (NFA). As of January 1, 2026, the federal transfer tax on suppressors was reduced to $0 under the One Big Beautiful Bill Act — but the item remains fully regulated. Before taking possession, the buyer (or their trust/entity) must still have an approved ATF Form 4 transfer application on file, along with fingerprints, photos, and a completed NFA background check (no tax payment is due). Current eForm approval times are running roughly 10 days for individuals and about 26 days for trusts (as of spring 2026), though times vary. The rifle must be transferred through Western Sport’s SOT/Class 3 process to a licensed dealer in the buyer’s state, and some states restrict or prohibit civilian suppressor ownership outright. Western Sport cannot advise on individual compliance — buyers are responsible for following all applicable federal, state, and local law.

Frequently Asked Questions

Q: What ammunition works best with the .300 AAC Blackout in this ISR?

A: The 1:8 twist rate and tuned pistol-length gas system handle both subsonic (220–240 grain) and supersonic (110–147 grain) .300 AAC Blackout loads reliably. Subsonic rounds deliver exceptional quiet performance when suppressed; supersonic rounds provide longer-range velocity. Test both to find what your barrel prefers.

Q: What optics and accessories mount to the KeyMod handguard and rail system?

A: The continuous top Picatinny rail accepts any standard red dot, scope, or magnified optic. The KeyMod slots on the sides and bottom mount lights, lasers, grips, and sling attachments from any KeyMod-compatible manufacturer. This modularity lets you build exactly the rifle you need.

Q: Does the integral suppressor affect accuracy or point-of-aim compared to other rifles?

A: The integral suppressor is part of your barrel assembly and point-of-aim is fixed from the factory. You won’t need to re-zero when attaching or removing a separate can, because there is none. This design delivers consistent accuracy and simplified maintenance.

Q: What comes in the box, and what warranty does Daniel Defense provide?

A: Your ISR ships fully assembled, test-fired, and ready to run suppressed. Daniel Defense backs every rifle with a lifetime warranty against defects in materials and workmanship. Western Sport also provides detailed documentation and after-sale support for all your questions.

Q: What is the KeyMod handguard on this rifle?

A: KeyMod is a slim attachment system that lets you mount lights, lasers, and foregrips directly onto the handguard without separate rail sections. Additionally, the Daniel Defense MFR XL 15.0 handguard floats independently of the barrel, so attachments don’t shift your zero. A continuous top Picatinny rail still provides a stable mounting surface for optics and iron sights.

Q: Do I need to file ATF paperwork or pay a tax stamp for this rifle?

A: Yes, but only for the integral suppressor — not the rifle itself. Because the suppressor is permanently welded to the barrel, the overall barrel length meets the 16-inch minimum, so this is not a Short-Barreled Rifle. However, the suppressor is a Title II item under the NFA. As of January 1, 2026, the federal transfer tax on suppressors dropped to $0, so you’ll need an approved ATF Form 4 and a completed background check before taking possession, but no tax payment is due.
