The recoil system is hydropneumatic. During run-out the breech is opened by a semi-automatic cam and the empty case ejected; the breech remains open ready for reloading.

Production as required. Installed in the FV101 Scorpion; Cougar (6 x 6) wheeled fire support vehicle (in service with Canada). The 76 mm Scorpion has now been withdrawn from service with the British Army.
