Wise Arms WA-15B .300 Blackout 16" - AR-15 Rifle

Subsonic stealth or supersonic punch — the Wise Arms WA-15B .300 Blackout 16" handles both. Built around .300 Blackout, it transitions effortlessly between suppressed and standard use without changing magazines or lowers.

Built as a semi-automatic AR-15 rifle around .300 Blackout and a direct impingement system, the Wise Arms WA-15B .300 Blackout 16" delivers a proven AR-15 experience from first round to last.

Quiet Subsonic Performance: Paired with a suppressor, subsonic .300 Blackout ammunition makes this one of the quietest centerfire rifles available — hearing-safe shooting without sacrificing reliability.

Full-Power Supersonic Option: When suppression is off the table, supersonic loads deliver genuine ballistic performance — substantially more energy than 5.56 at short to medium range.

Simple AR-15 Integration: This caliber requires only a barrel and BCG change from a standard 5.56 setup. Lowers, stocks, grips, and magazines remain the same — no new platform required.

Hunting and Defense in One: The .300 Blackout occupies a unique niche: subsonic for quiet defense and pest work, supersonic for hunting and extended-range use from the same rifle.
