GLOCK is an electronic firearm, or rifle, that uses a fully-automatic, self-loading mechanism. It has been manufactured since 2012.

The design is based on the weapon M16 A4, but with a shorter barrel and stock, and the design of the trigger, safety, and loading mechanism. The gun can be used in both fixed and semi-automatic mode. The semi-automatic mode is a user-selectable option.

The gun can be purchased as pre-built and ready to use, or as a DIY project. The pre-built version has a larger magazine and has a flashlight and laser light, as well as a sound and vibration mode.
