- Three 30-round polymer STANAG-pattern magazines, including one Hexmag polymer magazine with honeycomb texture and 5.56x45 NATO marking; two additional polymer magazines with orange followers (brand not confirmed)
The lower receiver is an Aero Precision Model X15 marked "MODEL X15," "CAL MULTI," and "AERO PRECISION LLC, TACOMA, WA," with selector pictograms. It is matched to a Palmetto State Armory flat-top upper receiver that has T-markings from T4 to T12, a forward assist, and an ejection-port cover.
The 10.5-inch 5.56 NATO barrel is threaded and capped with a thread protector (no muzzle device installed). A low-profile gas block sits under a free-float aluminum M-LOK handguard, which is marked "M-LOK" and "MADE IN USA" and provides a continuous top rail.
Furniture includes a tan polymer pistol stabilizing brace with a QD sling socket and hook-and-loop strap, plus a Magpul MOE FDE grip. Both receivers are 7075-T6 aluminum with a Type III hardcoat anodized finish.
The build accepts standard AR-15/STANAG magazines and has a 30+1 capacity. Sights are not included. Overall, this PSA upper and Aero Precision lower combination delivers a clean, purpose-built AR pistol configuration made in the USA.
