The history of the firearms industry shows that nearly every mechanical engineering achievement with expired patents, such as the 1911, Hi-Power, Glock 17, Inertia Drive Benellis, Smith & Wesson J-frames and so on, have been copied at some point, and Heckler & Koch’s MP5K is no different in that regard. Debuted in the mid-1960s by German manufacturer Heckler & Koch, the MP5 submachine gun has been a mainstay amongst tactical arsenals around the globe, and it is no wonder companies such as Military Armament Corporation are cloning that successful design today. Watch our video above to see the MAC-5K in use on the range.
The MAC-5K is proof of Military Armament’s capacity for executing a faithful copy of the ever-popular MP5K, sans select-fire operation. Like the German gun, the MAC-5K emulates the shorter version, with “K” in its name representing “kurz,” which means “short” in German. It is chambered for 9 mm Luger cartridges and features HK’s proven roller-delay mechanism with semi-automatic operation and more. In fact, it is such a great clone that parts compatibility with HK’s version are seamless, and there’s rich aftermarket support in the way of parts and accessories.
Like the MP5, the MAC-5K is supplied with a stamped-steel upper receiver covered with a black lacquer finish. The lower is made of polymer, which is where you’ll begin to notice subtle differences between this clone and the original gun. The fore-end is, too, made of polymer and features a built-in handstop. The altered grip shape of the MAC-5K provides a more ergonomically friendly feel, with built-in finger grooves and thumb shelf.
Operating the MAC-5K is quite simple, however an arm brace or sling will help with efficiency on target. There’s a fine set of sights up top to get you on target right out of the box and two 30-round magazines are included to make that first range visit more enjoyable. Controls are straightforward, slap the forward-mounted charging handle and flick the left-side safety lever to fire and enjoy shooting. A phosphate-finished 5.8” barrel is included, too, and comes with a machined-in tri-lug suppressor mount, which is also used in conjunction with the provided flash hider. A fluted chamber is also utilized to ensure reliable operation.
On the range our testers particularly enjoyed the MAC-5K. Its short overall length lends well to close-quarter work, and its manual of arms that mirrors that of the classic MP5 we’ve come to expect is a boon to its effectiveness. Should an optic be desired, however, we like that the MAC-5K is compatible with HK’s claw mount, too. Add the fact the MAC-5K comes in a hard case with plenty of accessories, and at just under four-and-a-half pounds and 14 inches long, the MAC-5K is a true standout defender with a palatable price-point—what’s not to love?
