The projectile consists of a sub-projectile and a sabot. The sub-projectile comprises a steel penetrator and a tracer assembled in the fin assembly. This is contained within a 3-piece aluminium Discarding Sabot, held in place with a plastic band at the forward end and a plastic obturating band at the rear end of the sabot. The projectile is crimped to the cartridge case which is loaded with cool burning, multi-perforated, loose propellant. The form, weight and ballistics of the M663 provide a good match to the

M652A1 round. Applications include for use with current in-service 90mm Cockerill MKIII and ENGESA EC-90 light guns for gunnery training.
