About this product
The Wise Arms WA-15B .300 AAC Blackout 10.5in SBA3 Pistol is a compact, AR-style semi-automatic pistol built for shooters who need a short, maneuverable platform without sacrificing terminal performance. Chambered in .300 AAC Blackout, this pistol uses a 10.5-inch threaded barrel and the popular SBA3 pistol brace to deliver a stable, close-quarters-capable package. The receiver is machined from billet aluminum and finished in a striking white Cerakote. It ships with one 30-round magazine and a canvas carry bag. This is a ready-to-run pistol for training, range work, or home defense.

Key Features
- 10.5-inch Threaded Barrel – Why it matters: This barrel length keeps the overall package compact for close-quarters handling while still providing enough velocity for .300 Blackout rounds to expand reliably. The threaded muzzle lets you attach a suppressor or muzzle device without a gunsmith.
- SBA3 Pistol Brace – Why it matters: The SBA3 gives you a stable shooting platform with an adjustable length of pull, making it easier to control rapid fire and transition between positions. It’s ATF-compliant as a pistol brace and doesn’t require a tax stamp.
- Billet Aluminum Receiver – Why it matters: Machined from a solid block, this receiver is stronger and more precise than forged receivers. It reduces flex and ensures consistent accuracy shot after shot.
- White Cerakote Finish – Why it matters: This isn’t just for looks. Cerakote provides excellent corrosion resistance and durability, and the white color is highly visible for low-light training or range use.
- Includes 30-Round Magazine and Canvas Carry Bag – Why it matters: You get everything you need to hit the range immediately. The bag protects the pistol during transport and storage.
Who It's For
This pistol is for the shooter who wants a compact .300 Blackout platform for home defense, truck gun use, or training in close-quarters tactics. It’s also ideal for anyone who wants to suppress their firearm later—the 10.5-inch barrel and threaded muzzle are suppressor-ready. New shooters will appreciate the SBA3 brace’s stability, while experienced shooters will value the billet receiver’s precision.

The WA-15B offers a .300 Blackout chambering and a longer barrel than typical 9mm pistols from Zev or Lone Wolf, making it a better fit for shooters who want rifle-like performance in a pistol format. The billet receiver and Cerakote finish add value over forged competitors.
FAQ
Is the Wise Arms WA-15B legal to own as a pistol?
Yes. The WA-15B is classified by the ATF as a pistol. It has a 10.5-inch barrel, no stock, and uses a pistol brace (SBA3). You do not need a tax stamp to purchase or own it. Always check your state and local laws before purchasing.
Can I attach a suppressor to this pistol?
Yes. The barrel is threaded (standard 5/8x24 thread pitch for .300 Blackout). You can attach a compatible suppressor directly. The 10.5-inch barrel is long enough to cycle subsonic ammunition reliably with a can.
What type of ammunition does this pistol use?
It uses .300 AAC Blackout ammunition, both supersonic and subsonic. The 1:7 twist rate stabilizes bullets from 110 to 220 grains. Use supersonic for hunting or defense, subsonic for suppressed shooting.
Does the pistol come with a case?
Yes. It ships with a canvas carry bag that fits the pistol and one magazine. The bag is padded and has a zipper closure.
Can I change the brace to a different model?
Yes. The SBA3 brace uses a standard carbine buffer tube. You can replace it with any other pistol brace or a stabilizing arm brace that fits a carbine tube. Always follow ATF regulations regarding modifications.
