Built on a Ruger AR-556 lower receiver marked with the Ruger phoenix and RUGER MAYODAN, NC USA, this pistol uses a direct impingement system and is chambered in 5.56mm NATO. The upper includes forward assist, ejection-port cover, and case deflector, with a 7-inch barrel and a threaded muzzle capped by an aftermarket multi-chamber pronged brake/flash hider.
The free-float aluminum M-LOK handguard provides modern accessory mounting while keeping weight forward of the receiver low. A continuous top rail runs from receiver through the handguard, and polymer flip-up front and rear sights are installed as backup irons.
A Toolcraft bolt carrier group drives the action. Controls include a manual safety selector and an A2-pattern polymer grip. The pistol is fitted with a Mission First Tactical Battlelink-style pistol stabilizing brace made of polymer and equipped with a QD socket.
An ejection-port cover engraved with a Jolly Roger icon and ARRGH text sets this build apart visually. The overall matte black finish keeps the look clean and consistent. Capacity is 30+1 using detachable STANAG-pattern magazines, and one 30-round magazine is included.
A SIG Sauer Romeo5 red dot optic is installed on a riser, providing an immediately usable sighting solution. This U.S.-made setup integrates compact dimensions with dependable components and a clear, ready-to-use sight picture.
