I did a quick Google search and came up with a different kind of Hekate related to a different kind of PGM
The Hecate II is the standard heavy sniper rifle of the French Army, sometimes known as the FR-12,7 (French: Fusil à Répétition de calibre 12,7 mm or "12.7 mm caliber bolt-action rifle").
It is manufactured by PGM Précision of France. This is the largest weapon manufactured by PGM, chambered for the .50 BMG (12.7x99mm NATO) cartridge.
Its design is the same metallic-skeleton as used in other similar rifles in the PGM family, only scaled up. It is equipped with both an adjustable front bipod and a rear monopod for maximum accuracy. The barrel is deeply fluted in order to disperse heat and reduce weight, and is fitted with a high-efficiency muzzle brake which reduces the felt recoil to about the level expected of a 7.62x51mm NATO-chambered rifle. The stock is also adjustable.
It is used as an anti-materiel rifle for demolition shooting at long ranges, harassing fire, counter-sniping and the destruction of unexploded ordnance from a safe distance, with High Explosive Incendiary/Armour Piercing Ammunition (HEIAP).
Standard issue sight is a SCROME LTE J10 F1 10x telescope.
