The modern patrol and precision shooter needs a versatile platform that bridges close-quarters capability with accurate, controllable fire at moderate distances. The WISE ARMS WA-15B is built around the increasingly popular .300 AAC Blackout cartridge and delivers a balance of suppressed performance, durability, and modular accessories for mission-focused operators and serious enthusiasts.

WISE ARMS WA-15B

Design and key features

This build centers on a 16-inch heavy-profile 300 Blackout barrel with a pistol gas system and standard flash hider, giving reliable operation with both supersonic and subsonic loads—ideal for suppressed setups and short-barrel ballistics. The rifle ships with a billet lower receiver and an oversized trigger guard machined in, plus a 3.5 lb trigger spring kit for a crisp, predictable pull.

The upper, lower, and handguard are finished in a complete Cerakote Sniper Gray for a low-glare, durable protective coating. A forged upper receiver includes a forward assist and dust cover; the bolt carrier group is a Black Nitride M16 BCG paired with a standard charging handle. The build uses a mil-spec lower parts kit and a mil-spec six-position buffer kit and stock for familiar ergonomics and field-serviceable parts.

Rail, handguard, and accessories

The WA-15B features a 15-inch modular handguard configuration to accept accessories; the listing highlights a 15″ M-LOK rail while some documentation references KeyMod style compatibility. Either way, the long free-float handguard gives ample real estate for optics, lights, and backup sights. The rifle ships with one 30-round magazine and a canvas carry bag for transport and storage.

Why .300 AAC Blackout?

.300 Blackout excels in suppressed applications and delivers heavier-for-caliber bullets at reduced velocity for effective short-range terminal performance. For hunters, tactical shooters, or anyone running a mixed supersonic/subsonic loadout, the WA-15B’s barrel and gas system are optimized to run consistently across those loads.
