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

The POF USA Minuteman .300 Blackout 13.75" turns your standard AR-15 lower into a hard-hitting .300 Blackout platform that excels suppressed, unsuppressed, and everywhere in between — no new lower, no new mags required.

Built as a semi-automatic AR-15 rifle around .300 Blackout and a direct impingement system, the POF USA Minuteman .300 Blackout 13.75" delivers a proven AR-15 experience from first round to last.

Built for Suppressors: The .300 Blackout cartridge was engineered from the ground up for suppressed use. Subsonic loads run quietly and cycle reliably — the standard for an effective suppressed AR-15.

Supersonic Versatility: Swap to supersonic loads and this platform delivers hard-hitting terminal performance at practical carbine ranges — making it a genuinely dual-purpose rifle for hunting and defense.

Lower Compatibility: Standard AR-15 lower receivers and STANAG magazines work without modification. Only the barrel and BCG are caliber-specific, protecting your existing investment.

Effective Hunting Caliber: Supersonic .300 BLK loads produce enough energy for deer and medium game at moderate ranges, extending the practical role of this AR-15 beyond range and defense use.
