The BATFE insisted that all future semi-automatic firearms were to be manufactured with a closed-bolt design as the open-bolt semi-automatics were considered too easy to illegally convert to full automatic operation. RPB Industries made many open-bolt semi-automatic and sub-machine guns before the Bureau of Alcohol Tobacco Firearms and Explosives (BATFE) seized roughly 200 open-bolt semi-autos during the drug wars of 1981. Some of the previously completed guns, which were already stamped with MAC, were then stamped with RPB on the reverse side, making it a "double stamp" gun.

As the Military Armament Corporation was in bankruptcy, a large number of incomplete sheet metal frame flats were given serial numbers and then bought by a new company, RPB Industries. In the United States, machine guns are National Firearms Act items. Law enforcement bureaucracies such as the Minnesota Bureau of Criminal Apprehension (BCA) consider MAC-11 variants such as the Leinad PM-11 to be part of the "MAC-10 class pistol." 380 ACP (9×17mm) and the M-11/9, which is a modified version of the M-11 with a longer receiver chambered in 9×19mm, later made by SWD (Sylvia and Wayne Daniel), Leinad and Vulcan Armament.

45 ACP or 9mm, the M10 is part of a series of machine pistols, the others being the MAC-11/ M-11A1, which is a scaled-down version of the M10 chambered in. While the original M10 was available chambered for either. The original Sionics suppressor is 11.44 inches in length, 2.13 inches in overall diameter, and weighs 1.20 pounds. This was one factor that led to the bankruptcy of Military Armament Corporation, another being the company's failure to recognize the private market.
During the 1970s, the United States placed restrictions on the export of suppressors, and a number of countries canceled their orders as the effectiveness of the MAC-10's suppressor was one of its main selling points.
The suppressor, when used with a Nomex cover, creates a place to hold the firearm with the secondary hand, making it easier to control. It is also very quiet, to the point that the bolt can be heard cycling, along with the suppressed report of the weapon's discharge, though only if subsonic rounds are used (standard. This uniquely shaped suppressor gives the MAC-10 a very distinctive look. This suppressor has a two-stage design, with the first stage being larger than the second. The primary reason for the original M10 finding recognition was its revolutionary sound suppressor designed by Mitchell WerBell III of Sionics.

Noting the weapon's poor precision, in the 1970s, International Association of Police Chiefs weapons researcher David Steele described the MAC series as "fit only for combat in a phone booth". That of the 9mm is approximately 1250, and that of the smaller MAC-11 in. 45 ACP is approximately 1090 rounds per minute. The original rate of fire for the M10 in. Ingram added a small bracket with a small strap beneath the muzzle to aid in controlling recoil during fully automatic fire. At the suggestion of the United States Army, the suppressor also acts as a foregrip to inhibit muzzle rise when fired. 45 ACP versions, as most loads are subsonic already, as opposed to special, low-powered subsonic loads usually required for suppressed 9mm weapons. The barrel is threaded to accept a suppressor, which works by reducing the discharge's sound without attempting to reduce the speed of the bullet. In addition, this design incorporates a built in feed ramp as part of the trigger guard (a new concept at the time) and, to save on cost, the magazine was recycled from the M3 Grease Gun. The M10 fires from an open bolt, and the light weight of the bolt results in a rapid rate of fire. This allows a more compact weapon and balances the weight of the weapon over the pistol grip, where the magazine is located. The M10 has a telescoping bolt, which wraps around the rear face of the barrel. A notched cocking handle protrudes from the top of the receiver, and turns the handle 90°, locks the bolt, and acts as an indicator the weapon is unable to fire. The M10 is built predominantly from steel stampings.
