POF USA Minuteman .300 Blackout 13.75" - AR-15 Rifle

Purpose-built for the full range of what .300 Blackout can do, the POF USA Minuteman .300 Blackout 13.75" moves seamlessly from quiet subsonic use to full-power supersonic performance — a genuinely versatile AR-15 build.

The POF USA Minuteman .300 Blackout 13.75" brings .300 Blackout capability to a semi-automatic AR-15 rifle, using a direct impingement operating system designed for dependable function in any condition.

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.

Uses standard AR-15 lower receivers and STANAG magazines. Shares lower receiver and magazine compatibility with 5.56 platforms — only barrel and BCG are caliber-specific.

A natural choice for suppressor owners, hunters in close-cover terrain, and shooters who want hard-hitting performance in a compact package. Supersonic and subsonic loads both perform as designed.
