Built on an Aero Precision X15-marked lower receiver (CAL MULTI), this pistol uses an aluminum, black anodized receiver set with a flat-top upper that includes a forward assist, shell deflector, and ejection-port cover. It operates via a semi-automatic, direct impingement system and is chambered in 5.56mm NATO, accepting standard STANAG magazines.
The upper features Geissele components, including the Geissele Airborne Charging Handle (PN 05-497), which offers an ambidextrous, reduced-profile design. A Geissele-marked upper part is present, and a low-profile gas block manages the gas system under the handguard. FEATURE GEISSELE UPPER.
A free-float aluminum M-LOK handguard runs the length of the fore-end with a continuous 12 o'clock Picatinny rail. Numbered T-slots from 2 to 46 and M-LOK slots at the 3, 6, and 9 o'clock positions support consistent accessory placement and repeatable positioning.
The 14.5 inch barrel is threaded and fitted with a gold/brass-toned multi-port brake/compensator. This setup pairs durability with a distinctive look at the muzzle while retaining standard threaded compatibility for future device changes.
Furniture and controls include a smooth pistol buffer tube outfitted with an SB Tactical pistol brace featuring a Velcro strap, and a Magpul MOE polymer grip. The pistol carries a 30+1 capacity with the included PMAG and is finished in black. Made in the United States.
