MAC IX | 9mm | 6.5" | Tailhook Brace | 30rd Pistol

The Military Armament Corporation MAC IX (MPN: 12755002) is a modular 9mm pistol-caliber platform built around a direct-blowback operating system and MP5-style magazines. The compact 6.5-inch barrel, retractable Tailhook brace, monolithic-style upper, and accessory-ready handguard give the MAC IX a configuration aimed at shooters who want PCC-style handling in a pistol format.

The barrel is threaded 1/2x28 for compatible muzzle devices. A full-length Picatinny top rail runs along the upper, while M-LOK slots on the handguard provide additional mounting space. Adjustable folding front and rear sights are included, along with a thumb safety and two 30-round magazines. The anodized black finish keeps the appearance consistent across the receiver and handguard.
