Like other world powers of the post-World War 2 era (1946-onwards), the nation of Argentina moved to adopt a new Submachine Gun (SMG) weapon for close-quarters combat. Like other designs of the time, the new system fired the ubiquitous 9x19mm Parabellum German pistol round. The weapon, entering service in or around 1957, became the Halcon ML-63 series SMG and saw combat service during the Falklands War of 1982. Users included the Argentine Army, Air Force, Navy, national police elements, federal the police force, and prison security forces.

The submachine gun was arranged in a conventional way. The receiver made up the primary mass of the weapon and was rectangular in its general shape. The short barrel assembyl protruded a short distance ahead of the receiver and was capped by a muzzle brake fitted the forward sight. A rear sight was affixed to the aft upper section of the receiver. The pistol grip sat near the trigger unit in the usual fashion with the magazine well set some distance ahead the trigger proper. Into this well was inserted a straight 30-round detachable box magazine. The well featured an extension that acted as the foregrip. At the rear of the frame was the shoulder stock and two forms could be used ? a solid wooden stock variant and a two-strut wired form that could be slide into the receiver fro a more compact form.

Beyond this, the ML-63 existed in a known silenced version for clandestine work.

Performance specifications included a rate-of-fire nearing 600 rounds-per-minute with an effective range of about 100 meters.©MilitaryFactory.com
