Designed to fit Sig Sauer Models: P365 XL, P365 XMACRO, P365 XMACRO Tacops - non-compensated versions.

Upgrade your SIG Sauer P365 XL with the NDZ Performance A.R.E.S. Ported Barrel, a precision-engineered replacement designed exclusively for use with the NDZ Performance A.R.E.S. Slide. Built as a matched system, the A.R.E.S. barrel features integrated porting that aligns with the slide's lightening windows to deliver improved recoil management, reduced muzzle rise, and faster follow-up shots without compromising reliability or accuracy. Precision CNC machined from premium stainless steel, the A.R.E.S. Barrel is engineered for exceptional fit, consistent lockup, and dependable performance. Strategically placed barrel ports redirect expanding gases upward to help minimize felt recoil and muzzle flip, allowing shooters to stay on target and transition between shots more quickly. Combined with a hand-polished feed ramp, precision target crown, SAAMI-spec chamber, and advanced broach-cut rifling, the A.R.E.S. Barrel delivers reliable feeding and outstanding accuracy with a wide variety of 9mm ammunition. Available in a variety of premium PVD finishes—including Black, Silver, Shadow Grey, Copper, Spectrum (Rainbow), and additional color options—the A.R.E.S. Barrel allows you to customize your P365 XL while maintaining the premium performance and American-made quality expected from NDZ Performance. Whether you're replacing an existing A.R.E.S. barrel or completing your A.R.E.S. slide assembly, this barrel delivers the precision, reliability, recoil reduction, and custom styling serious shooters demand.

Important: The NDZ Performance ARES Barrel is designed specifically to function with the NDZ Performance ARES Slide. The barrel porting is engineered to align with the ARES slide window configuration and is not intended for use with factory Sig slides or other aftermarket slide designs.
