MAC IX 9mm 6.5 in Barrel Semi-Auto PCC Pistol

The MAC IX is a modular 9mm pistol-caliber carbine that blends MP5 magazine reliability with modern ergonomics. Its monolithic 7075-T6 upper and M-LOK® hand-guard ride a full-length Picatinny rail, giving nearly 16 in of uninterrupted real estate for optics, BUIS or night-vision bridges. The 6.5-in cold-hammer-forged barrel ends in a factory tri-lug plus 1/2-28 thread.

Internally, a direct-blow-back action keeps parts count low and recoil even lower, while a 30-rd curved MP5-pattern magazine (two are included) snaps home with either the HK-style paddle or AR-style button release. Ambidextrous safety levers, a flared mag-well and a last-round bolt hold-open round out the modern controls.

Despite its compact footprint, 15.97 in. OAL, 8 in. high, 1.75 in. wide, 5.1 lb. unloaded—the MAC IX is built for hard use: the hard-coat-anodized 6061 lower, nitrided bolt and steel reinforcements shrug off high-round-count range sessions. Detachable AR/M4-pattern sights ride up top; swap them for your favorite red-dot in seconds. A rear Pic-rail section is machined in for braces or stocks (all NFA rules apply).

Included Accessories:

Hard case, 2 × 30 Rd mags, cleaning kit, sling, owner’s manual.
