The Denel GI-2 is based on the GIAT Modèle F2 gun design, for which Denel has a production license.

The 20 mm GI-2 is a mounted monotube gun, with two 150-cartridge boxes on each side of the piece.

After each shot, the empty cartridge is ejected from beneath the weapon.

A hydraulic rearming device is available for naval or land versions.
