Gyrojet - as applies to 9mm, Ares is the Slovak compnay of Jozef Mongel, named “ARES, Puskarska Diecna,” located at Dopravna 5, 956 01 Topllcany, Slovakia. The are primarily a reloading company, although they have had their own headstamp on some rounds. They load only 9mm Para, with a variety of bullets, often colored different colors (red, blue, green, black, etc.), and 12 Gauge. I think the color denotes the weight and style of the bullet. I could be wrong about that, but I have a box from them labeled “9MM LUGER 125 grs RED.” They also sell cast bullets, and some firearms and airguns. Their box label indicates they are a gunsmithing workshop as well.
Regarding the meaning of “ARES”, he was, in Greeek Mythology, the son of Zeus and Hera, the Olympian God of Warfare (according to Wikopedia, more properly called "the God of savage warfare, bloodlust or slaughter). In Roman Mythology, they identify the same figure as “MARS”, God of Warfare and Agriculture.
The Slovak Company “ARES” depicts the Greek God Ares sitting on a rock, leaning on his sword, with his shield at his side, so there is no doubting that we are discussing the correct “Ares” when it comes to the Slovak firm.
I have no idea if they have anything to do with the plastic link in question, but I seriously doubt it.
