Built on an Aero Precision M4E1 lower marked "MOD M4E1 / CAL MULTI," this AR-15 platform pistol pairs that foundation with a Palmetto State Armory upper receiver. Chambered in .300 AAC Blackout, it runs an 8-inch barrel and a threaded muzzle capped by an open-prong multi-port brake/compensator. The matte black aluminum receivers and free-float aluminum handguard keep weight down and rigidity up.
The handguard provides a full-length Picatinny rail up top with M-LOK slots for accessories. A Magpul polymer ejection-port cover is installed. The configuration uses STANAG-pattern magazines and is shown with a dedicated .300 BLK PMAG.
Controls and ergonomics are a standout: a Daniel Defense Grip-N-Rip ambidextrous charging handle, an ambidextrous mil-spec safety selector from a DDM4, an ambidextrous magazine release, and a bolt-catch extension lever (B.A.D.-style) are all onboard. A BCM pistol grip, a Magpul RVG vertical foregrip, and a pistol stabilizing brace with a hook-and-loop strap round out the handling package.
The bore presents in excellent condition with a clean, mirror finish and sharp lands and grooves, consistent with careful use and maintenance.
