Shopping for a MAC

“Entry level” Submachine Gun Presents Many Versions to Choose From

The MAC submachine guns are considered by many as an inexpensive “entry level” choice. However, inexpensive is hardly a word that can be used to describe any transferable machine gun today.

MACs, because of their high cyclic rate, are thought of as bullet hoses that are able to consume large quantities of ammunition in a very short period of time. Being a spray and pray type of submachine gun, the diminutive weapons are often viewed as merely a novelty item. Unfortunately, the novelty of quickly expending hundreds of rounds of ammunition wears off quickly. The time spent loading the magazines can also become wearying. However, there are a few folks that find dumping a magazine from a fast-cycling MAC an exhilarating experience.
Various devices and components for reducing the MAC’s cyclic rate have been conceived since MACs hit the market in the 1970s. The most successful have been those of Lage Manufacturing LLC. Not only have Lage products made the MACs more ergonomic and tamed their cyclic rate, they have also made MACs very popular.

Lage’s MAC products have been covered in previous SAR articles. This piece is to review what is available to those interested in adding a MAC to their collection.

In addition to the original MACs made in Powder Springs and Marietta, Georgia, there have been several other companies that have manufactured the basic design since the original Military Armament Corporation went bankrupt in 1976.

The MAC submachine guns are usually identified by the address or addresses marked on their lower receivers:

Military Armament Corp Powder Springs, GA
Military Armament Corp Marietta, GA
Military Armament Corp Powder Springs / RPB Industries Inc., Atlanta, GA (double stamp)
Military Armament Corp Marietta, GA / RPB Industries Inc., Atlanta, GA (double stamp)
