Video review
Expert review
About this product
The Wise Arms WA-15B is a Title II-compliant 10.5-inch barreled AR-pattern pistol chambered in 5.56 NATO that ships with an SBA3 brace and M-LOK handguard. This configuration prioritizes compact maneuverability while maintaining full AR-15 parts compatibility, making it ideal for shooters who understand NFA regulations but want factory-built reliability. At 9.6 pounds unloaded and 26.5 inches overall length, it balances stability with close-quarters handling.
What is the Wise Arms WA-15B used for?
The WA-15B serves as a compact defensive or training platform where full-length rifles are impractical. Its 10.5-inch barrel produces 5.56 NATO ballistics with approximately 2,750 fps muzzle velocity from M193 ammunition, effective within 200 yards. The SBA3 brace provides cheek weld stability for rapid follow-up shots, while the 7-inch M-LOK handguard accepts lights, lasers, or vertical grips.
How does the Wise Arms WA-15B compare to the Stevens 334 Rifle?
The WA-15B offers higher firepower density than the bolt-action Stevens 334 in .308 Win, trading long-range precision for close-quarters volume. Where the Stevens 334 delivers sub-MOA accuracy at 100 yards with match ammunition, the WA-15B provides semi-automatic 30-round capacity in a package 8 inches shorter. For home defense or vehicle-based scenarios, the WA-15B's rate of fire and compactness outperform bolt guns.
What does it weigh and what are the dimensions?
This pistol weighs 9.6 pounds empty and measures 26.5 inches from muzzle to brace end. The 10.5-inch barrel has 1:7 twist rifling optimized for 62-grain ammunition, while the 7-inch handguard provides 21 M-LOK slots for accessories. Overall height with magazine inserted is 7.75 inches, keeping it low-profile for storage or transport.
Who is this NOT for?
Avoid this platform if you prioritize long-range precision or live in states restricting pistol braces. The 10.5-inch barrel sacrifices approximately 400 fps velocity compared to 16-inch barrels, reducing effective range beyond 200 yards. Those seeking traditional shotguns for sporting clays should consider the Stevens 555 Sporting O/U instead.
What's in the box?
You receive one complete WA-15B pistol with SBA3 brace installed, one 30-round PMAG, and owner's documentation. The package excludes sights, cleaning tools, or additional accessories—budget $150-$300 for optics and a weapon light. All components ship in compliant packaging with trigger lock per federal regulations.
Is the Wise Arms WA-15B worth it at $729.99?
At $729.99, this represents solid value for a billet-built pistol with Cerakote finish and brace included. Comparable builds using Aero Precision or PSA parts typically cost $850+ when adding a $200 brace and professional coating. The main trade-off is the unthreaded muzzle device—plan $80-$120 for a qualified gunsmith to install a flash hider or suppressor mount.

Frequently asked questions
- Is it compatible with standard AR-15 parts?
- Yes, the WA-15B uses mil-spec AR-15 components except for the proprietary billet lower. The buffer tube, fire control group, and upper receiver accept aftermarket parts. The barrel nut requires a 1-3/16-inch armorer's wrench for removal.
- Does it fit in a standard rifle case?
- No, you'll need a pistol case or compact rifle bag. The 26.5-inch length requires a case at least 28 inches internal length. I recommend Savior Equipment's Urban Warfare 28-inch bag for transport.
- How long does shipping take?
- Firearms ship via FedEx 2Day within 3 business days after FFL verification. Allow 2 additional days for your FFL to process paperwork. Non-compliance states may experience longer delays.
- Can I return it if it doesn't fit my needs?
- Returns require 15% restocking fee and original packaging. Firearms must be unfired with all seals intact. Contact support within 7 days of FFL transfer completion.
- Does this work with SureFire suppressors?
- Yes, the 1/2x28 threads accept SureFire SOCOM muzzle devices. The 10.5-inch barrel generates sufficient gas pressure for RC2 suppressors. Expect increased gas blowback compared to 14.5-inch systems.
