MAC IX 9mm 6.5" 30rd Pistol

The MAC IX is a 9mm built on a simple idea: run direct blowback, feed it MP5 pattern magazines, and let people set the rest up how they want. Direct blowback keeps the parts count low and the recoil impulse soft in 9mm, and the MAC-5 and MP5 magazine compatibility means feeding it is a solved problem rather than a proprietary magazine hunt. The 6.5 inch barrel is threaded at 1/2x28 and the muzzle is machined with a tri lug mount, so both common attachment methods are covered without an adapter.

The upper is monolithic with a full length Picatinny rail, so an optic and a rear iron can share the top without a height mismatch, and the M-LOK handguard underneath takes lights and hand stops in the slots. The magazine release is a paddle and button setup, familiar to anyone who has run an MP5 pattern gun, and the receiver extension carries a retractable brace. It comes with two magazines. A short 9mm like this makes sense for people who want carbine controls and pistol ammunition in a package that stores easily, and the tri lug mount up front makes it an obvious suppressor host.
