An AR-15 style rifle is a lightweight semi-automatic rifle based on the Colt AR-15 design.

Coverage of high-profile incidents where various versions of the rifle were involved often uses the shorthand AR-15.

Construction is the process of constructing a building or infrastructure.

Construction differs from manufacturing in that manufacturing typically involves mass production of similar items without a designated purchaser, while construction typically takes place on location for a known client.

Construction as an industry comprises six to nine percent of the gross domestic product of developed countries.

Construction starts with planning, design, and financing; it continues until the project is built and ready for use.
