CAR-15

The Colt Automatic Rifle-15 Military Weapons System or CAR-15 was a family of AR-15 and M16 rifle–based firearms marketed by Colt in the late 1960s and early 1970s. Due to their compact size, the short-barreled Colt Commando and XM177 versions of this family continued to be issued to the U.S. military after the Vietnam War.

The CAR-15 name was an attempt to re-associate the AR-15 name with Colt, since the AR initially stood for ArmaLite Rifle, the original manufacturer. Colt later abandoned the CAR-15 concept, but continued to make variations, using the M16 brand for military-oriented models and the Colt AR-15 brand for law enforcement and civilian models. However, in present usage, CAR-15 is used as a generic name for carbine-length M16 and AR-15 variants from before the M4.

Specifically, "Colt Commando" currently refers to the ultrashort 11.5-inch barrel assault rifle of the Model 733 series. By comparison, the M4 Carbine has a 14.5-inch barrel, while the M16 assault rifle series has a 20-inch barrel.

Panhole

A panhole is a depressed, erosional feature found on flat or gently sloping rock. Panholes are the result of long-term weathering and are generally seen on bedrock or very large blocks of rock. Similar terms are gnamma (Australia), opferkessel (German, roughly “sacrificial basin”), “armchair hollows”, weathering pans (or pits) and solution pans (or pits). Other German names include kamenitza and kamenica. In Spanish they are tinajita. In Portuguese and Galician are called pias.

In Namaqualand these features are called !gau

These shallow solution basins, or closed depressions, tend to form on bare limestone or silicate rock. They are also found on granitic rock. They are generally characterized by flat bottoms and sometimes by overhanging sides. The initial form may be a closed hollow created by a patch of humus. Diameters are rarely greater than 15 centimeters

In the Sierra Nevada, California these features were termed weathering pits by François E. Matthes, where they are thought to indicate rock surfaces that are unglaciated or escaped more recent glaciations. In Sierra Nevada granitic rocks, these features have a characteristic shape such that they expand more rapidly in width than they grow in depth. One explanation for their conformation is because the most active environment for weathering is the zone of alternate wetting and drying along the margins of the pools that collect in the pits, the margins tend to deepen and enlarge until all points of the bottom are equally wet or dry at the same time, thus producing their characteristic shape.
