The Intratec TEC-22 is a semi-automatic handgun chambered in .22 Long Rifle. It was also marketed as the Scorpion and Sport-22. The TEC-22 operates using a straight blow-back action.

The TEC-22 is constructed largely from molded plastic and stamped metal parts. The materials used, along with its extremely simple design allowed the gun to be made and marketed inexpensively. The TEC-22 is designed to use magazines and drums made for the popular Ruger 10/22 rifle.

Over its production run, the TEC-22 suffered from various quality control issues. For example, some were recalled because they were firing automatic bursts.
