MSAr

MSAR is an acronym that may refer to several organizations and technologies, depending on the context. The two most common references appear in firearms and in search-and-rescue fields.

In firearms, MSAR stands for Microtech Small Arms Research, a United States-based manufacturer of AR-pattern rifles and accessories active in the late 1990s and 2000s. The company produced rifles intended for civilian and law-enforcement markets. After a period of activity, the firm ceased operations, and its products are now primarily of interest to collectors and researchers studying that era of civilian firearms development.

In search-and-rescue, MSAR is used to denote Mountain/Maritime Search and Rescue units. These teams may be volunteer or professional and are specialized in locating and assisting missing persons in mountainous terrain or on water, often operating in coordination with local or national emergency services. Training typically covers navigation, rope and water rescue techniques, and incident management.

Other uses of the acronym exist regionally and in different sectors, including academic or organizational contexts. Because MSAR has multiple meanings, identifying the intended referent requires contextual clues such as location, field, and organizational affiliation.
