Daniel Defense DDM4 V7P 300 Blackout LAW Tactical Pistol, Mil Spec+

Product Description

The V7P 300 BLACKOUT PISTOL LAW TACTICAL MIL SPEC is built for shooters who demand power in a compact platform. This pistol pairs Daniel Defense’s proven V7 receiver set with a 10.3″ cold hammer forged barrel tuned for both supersonic and subsonic .300 Blackout rounds. The result is a short-barrel pistol that delivers serious terminal performance without sacrificing portability.

This configuration uses a Mil-Spec lower receiver, which gives you broader aftermarket compatibility right out of the box. The compact MFR 9.0 M-LOK handguard stays lightweight while providing multiple mounting points for optics, lights, and accessories. An SB Tactical SBA3 stabilizing brace comes factory-installed, offering a steady platform for accurate shot placement.

Additionally, the included Law Tactical Folding Stock Adapter lets the brace fold to the side for storage and transport. Every Daniel Defense firearm is hand assembled, quality assurance tested, and test fired before it ships. This attention to detail means your V7P arrives ready to perform when you need it most.

Compact Power Meets Field-Proven Engineering

Moreover, the .300 Blackout caliber excels in short barrels, making this pistol ideal for home defense, truck storage, or tactical situations where space is tight. The cold hammer forged barrel ensures consistent accuracy and long service life. You’re holding a purpose-built tool that balances punch with practicality.

Specifications

This pistol ships from the factory with an SB Tactical pistol stabilizing brace attached to a pistol-length receiver extension, configured as a firearm — not a rifle. A 2024 federal court ruling vacated ATF’s 2023 rule that reclassified braced pistols as Short-Barreled Rifles (SBRs), and the government dropped its appeal of that ruling in 2025. As a result, a stabilizing brace alone no longer causes a pistol to be treated as an SBR under the National Firearms Act (NFA). As of 2026, ATF has proposed formally removing the old ‘redesigned to be fired from the shoulder’ factoring criteria, with public comments open through August 4, 2026. As configured and shipped, this pistol requires no NFA registration or tax stamp — only the standard ATF Form 4473 background check at transfer. Permanently configuring this firearm with a shoulder stock, however, would create an SBR requiring an approved ATF Form 1 before modification. Western Sport cannot advise on individual compliance — buyers are responsible for following all applicable federal and state law.

Frequently Asked Questions

Q: What ammunition does the .300 AAC Blackout caliber work best with?

A: The 10.3″ barrel is optimized for both supersonic and subsonic .300 Blackout loads. Supersonic rounds (above 1,125 fps) deliver rifle-like ballistics; subsonic ammunition excels in suppressed applications. Most shooters find quality factory loads from established manufacturers deliver consistent performance from this barrel length.

Q: What optics and accessories work with the MFR 9.0 M-LOK handguard?

A: The M-LOK mounting system accepts any M-LOK-compatible light, laser, sling attachment, or optic riser. Popular options include Surefire or Streamlight weapon lights, Picatinny M-LOK adapters for magnified scopes, and QD sling mounts. The top receiver rail also supports standard AR-15 optics like red dots and magnifiers.

Q: Does the Law Tactical Folding Adapter change how I maintain or shoot this pistol?

A: No—the folder simply allows the brace to collapse sideways when you’re not shooting. Functionality and accuracy remain unchanged when the brace is extended. Maintenance follows standard AR-15 procedures; the adapter adds zero complexity to field stripping or cleaning.

Q: What comes in the box, and do I need to register this pistol?

A: The V7P ships factory-assembled with the SB Tactical brace, Law Tactical adapter, and a test-fired receiver ready to go. As shipped, it requires only a standard ATF Form 4473 background check—no NFA registration or tax stamp. Western Sport handles all federal transfer procedures; we’ll guide you through your state’s requirements at purchase.

Q: What is the M-LOK handguard on this pistol?

A: Daniel Defense’s free-float M-LOK handguard lets you attach lights, lasers, and grips directly to the rail using the M-LOK slot system — no separate rail sections required. Additionally, the handguard floats independently of the barrel, so attachments don’t shift your zero. A continuous top rail provides a stable mounting surface for optics.

Q: Will I need to file ATF paperwork or pay a tax stamp for this pistol’s brace?

A: No. As configured and shipped, this is a pistol with a stabilizing brace — not a Short-Barreled Rifle (SBR). ATF’s 2023 rule treating braced pistols as SBRs was vacated by federal courts in 2024, and the government dropped its appeal in 2025. Only the standard ATF Form 4473 background check applies at transfer, the same as for any other pistol.

Q: What does the Law Tactical Folding Stock Adapter do on this pistol?

A: This pistol includes a Law Tactical Folding Stock Adapter, which lets the receiver extension and stabilizing brace fold to the side of the receiver for compact storage and transport. A single button releases the fold, and the mechanism automatically locks back into place once unfolded. Folding does not change the barrel length, configuration, or NFA status of the firearm.
