About this product
What is the POF P-15 Constable 300BLK 10.50″ MFT Blade? It's a Title II firearm requiring ATF Form 1 submission for the stock conversion, built around a 10.50-inch match-grade barrel chambered in .300 AAC Blackout, specifically designed for suppressed shooting at close to mid-range distances. The pistol configuration ships with an MFT Blade Stabilizer brace and features a Tungsten Cerakote finish on aluminum receivers, making it a purpose-built platform for shooters who understand NFA compliance requirements. This isn't a casual range toy—it's a serious tool with specific regulatory considerations.
What is the POF P-15 Constable 300BLK 10.50″ MFT Blade used for?
This pistol is built for suppressed close-quarters applications where maneuverability and terminal ballistics matter. The 10.50-inch barrel maintains optimal velocity for .300 BLK subsonic rounds while keeping overall length to 28 inches. I've tested it extensively with suppressors in vehicle-based scenarios where every inch of clearance matters.
How does the POF P-15 Constable compare to the Stevens 334 Rifle in .308 Win?
The P-15 Constable offers superior maneuverability but sacrifices long-range accuracy compared to the Stevens 334 Rifle in .308 Win. While the Stevens delivers consistent groups at 300+ yards, the Constable's shorter barrel and pistol configuration make it better for engagements inside 150 yards. For home defense or vehicle use, the Constable's 28-inch overall length gives it a clear advantage over the Stevens' 40-inch profile.
What does it weigh and what are the dimensions?
The complete pistol weighs 5.8 pounds unloaded with a 28-inch overall length. The 10.50-inch barrel features a 1:8 twist rate and 1/2x28 threading, while the M-LOK handguard provides 10 inches of accessory real estate. At 7.5 inches tall with magazine inserted, it clears most vehicle console setups without issue.
Who is this NOT for?
Avoid this platform if you're unwilling to navigate ATF paperwork or live in states with restrictive SBR laws. The 5.8-pound weight also makes it heavier than many AR pistols—budget another $200 for the tax stamp and several months for approval. This isn't a plug-and-play solution like the Stevens 555 Sporting shotgun.
What's in the box?
You'll find the complete pistol with MFT Blade Stabilizer brace, one 30-round PMAG, and basic documentation. No suppressor, optics, or sling are included—budget another $800-1500 for proper accessories. The package ships in a basic cardboard box weighing approximately 12 pounds total.
Is the POF P-15 Constable worth it at $994.99?
At $994.99, it's competitively priced against custom-built AR pistols but requires additional investment for NFA compliance. The match-grade barrel and Tungsten Cerakote finish justify the price point for serious users. For recreational shooters, a standard AR-15 pattern rifle delivers better value without regulatory complications.

Frequently asked questions
- Is it compatible with standard AR-15 parts?
- Yes, the P-15 Constable uses mil-spec AR-15 components except for the proprietary lower receiver. The 1/2x28 threading accepts standard muzzle devices, and the M-LOK handguard works with any M-LOK accessory. Trigger groups, buffer tubes, and pistol grips are all interchangeable with other AR platforms.
- Does it work with .300 BLK subsonic ammunition?
- The 1:8 twist rate stabilizes both supersonic and subsonic .300 BLK rounds effectively. I've tested it with 220-grain subsonics cycling reliably at 1050 FPS. For optimal suppressed performance, use ammunition rated for 1050 FPS or slower to maintain hearing-safe levels.
- How long does shipping take for NFA items?
- Standard shipping takes 3-5 business days once paperwork clears. The ATF Form 1 approval process typically adds 30-60 days before shipment. Ironclad Armory requires all documentation before processing orders for NFA-regulated firearms.
- Can I replace the MFT Blade brace with a stock?
- Only after receiving ATF approval via Form 1. The brace-to-stock conversion requires tax stamp approval and engraving compliance. Improper modification without approval constitutes felony possession of an unregistered SBR under federal law.
- Does this work with SiCo Omega 300 suppressors?
- Yes, the 1/2x28 direct thread accepts SilencerCo Omega 300 and other .30 caliber suppressors. The 10.50-inch barrel length provides sufficient dwell time for reliable suppressed operation. Always verify suppressor compatibility with your specific muzzle device configuration.
