Key Features

• Threaded 7.5″ Barrel – The 1/2×28 muzzle thread pattern lets you mount suppressors, compensators, or flash hiders directly, reducing recoil and muzzle rise while keeping the overall length short for close-quarters use.
• SBA3 Pistol Brace – Adjustable arm brace provides a stable shooting platform without requiring a tax stamp, making it legal to shoulder without NFA paperwork.
• ODG Cerakote Finish – Olive Drab Green Cerakote resists corrosion, scratches, and harsh weather, so the gun holds up to heavy range use and field conditions.
• Billet Aluminum Receiver – Machined from a solid block of 7075-T6 aluminum, this receiver is stronger and more rigid than forged receivers, improving accuracy and longevity.
• High-Capacity Magazine – Ships with a 30-round magazine, giving you more rounds between reloads for training or defensive drills.

Who It’s For

This pistol is built for shooters who want a compact .300 Blackout platform for suppressed shooting, home defense, or tactical training. If you need a short-barreled rifle-style pistol that’s easy to maneuver in tight spaces and accepts standard AR-15 accessories, this fits. It also suits collectors who want a factory-built ODG Cerakote gun without paying a premium for custom work.

Pros & Cons

• Pro: The 7.5-inch barrel is short enough to suppress effectively while still stabilizing .300 Blackout subsonic loads for quiet shooting.
• Pro: ODG Cerakote is a low-visibility finish that blends into natural environments, unlike black or FDE.
• Con: The 7.5-inch barrel loses velocity with supersonic .300 Blackout loads compared to longer barrels (e.g., 10.5 inches), so long-range accuracy drops beyond 200 yards.

Caliber	.300 AAC Blackout	9mm	9mm
Barrel Length	7.5 inches	4.5 inches	4.02 inches

The WA-15B offers a longer barrel and a rifle-caliber platform at a lower price point than comparably built handguns from Zev Technologies or Agency Arms. However, those competitors are chambered in 9mm, which is less expensive to shoot and easier to find in stock.

FAQ

Is this pistol NFA-regulated as a short-barreled rifle?

No. It ships with an SBA3 pistol brace, not a stock, so it is classified as a pistol under federal law. You can legally use it with a suppressor if you have the appropriate NFA tax stamp for the suppressor itself.

What muzzle devices fit the 1/2×28 thread?

Any muzzle device with a 1/2×28 thread pattern will work, including most .223/5.56 suppressors, compensators, and flash hiders. Just verify the bore diameter is large enough for .30 caliber if you plan to suppress it.

Does the ODG Cerakote chip or wear easily?

Cerakote is a ceramic-based coating that is more durable than standard anodizing or paint, but it can chip if you drop the gun on concrete or abuse it. Regular cleaning and storage in a padded case will keep it looking new.

Is this gun compatible with standard AR-15 parts?

Yes. The WA-15B uses a standard AR-15 lower and upper receiver pattern, so you can swap grips, triggers, handguards, and stocks (if you convert it legally) without custom fitting.

What is the effective range for .300 Blackout with this barrel?

With supersonic loads, expect reliable accuracy to 200-250 yards. With subsonic loads, maximum effective range drops to 100-150 yards due to velocity loss and bullet drop.
