The heart of this build is the Ballistic Advantage 10.5 inch upper assembly chambered in .300 AAC Blackout (7.62x35mm), paired with a threaded barrel capped by an A2-style birdcage flash hider. The platform is direct impingement and built on PSA's Sabre-series lower, offering a proven AR-15 foundation with aluminum receivers and a hardcoat-style finish.
A Microbest bolt carrier group and the LaRue MBT-2S two-stage trigger form a high-quality core for reliability and a clean, predictable trigger press. The receiver set includes a forward assist and ejection-port cover, and the upper shows an "A" forging mark on the rail.
Controls and ergonomics are well thought out. The Radian Raptor ambidextrous charging handle and ambidextrous safety levers support either-hand manipulation. Hogue furniture includes a collapsible carbine stock and an overmolded pistol grip with finger grooves for positive control.
The free-float aluminum M-LOK handguard provides a continuous 12 o'clock top rail and a QD sling socket installed at the 6 o'clock position. The flat-top Picatinny receiver rail and handguard top rail are uninterrupted for mounting as needed. No iron sights or optics are included.
Markings and identifiers include the PSA Sabre lower and additional magwell engraving "CUSTOMIZING UNLIMITED GUN TRUST, ROCKWALL, TX." Capacity is 30+1 with the included 30-round magazine.
