Status: In-Stock / Please Call to Purchase

This Chester County Armory listing is for an RPB Industries MAC M10 9x19mm NATO transferable sub machine gun with Lage MAX-10/9 mk2 upper and upgrades already installed.

This model was an original Military Armament MAC M10 receiver in 9mm Parabellum that was completed and registered by RPB Industries in Atlanta, GA after the closure of Military Armament Corporation in the early 1980’s. This model currently has a new condition Lage Manufacturing MAX-10/9 mk2 Slow Fire upper installed upon it, along with a new Lage folding left-side folding stock and Magpul Pro front and rear folding iron sights.  This MAC M10 model features a grip housing to accept the 9x19mm Zytel MAC magazines and will come with one 32rd magazine. In addition to the Lage upgrades, purchase of this model will also include the original RPB Industries 9x19mm NATO complete upper receiver and bolt assembly, along with its original telescoping wire stock.

Overall, this weapon package is in excellent condition. The original RPB MAC 10 upper and lower receiver show minimal wear and use marks. The original upper receiver has a barrel that remains very bright and shiny, with crisp, clean rifling. The original bolt grip notes only minor wear markings. The lower receiver is in excellent condition, with very minimal use marks noted on the fire control internals. The exterior of the lower receiver denotes only very minor handling marks in the original parkerization, and no dents, dings, cracks, or malformations of any type in the metal work. The original upper receiver is also structurally excellent, but the original finish one the upper has started to patina to a light brass to auburn color at spots in the original parkerization. The safety selector switch notes some minor finish wear.

The Lage MAX-10/9 upper was installed in new condition, along with new Magpul sights and a new condition Lage side folding stock. There are some minor handling/storage marks visible on the new condition upper. This upper has not been fired outside of any factory test firing.
