"MA7 Series"@en . "MA7 Series"@en . "The MA7 Series was a family of rifles used by the United Nations Space Command following the Human-Covenant War. Due to the ineffectiveness of the MA6 series, the UNSC military contracted Poseidon Industries to create the MA7 series. The result was five versatile and powerful firearms, ranging from a carbine to a light machine gun. The series drew heavily on its successful predecessor, the MA5 Series, most notably the MA5C Assault Rifle, taking design elements and inspiration from that series, and fully modernising and heavily updating it, improving its performance and bringing it up to date. The MA7 series was put in to active duty in early 2570, quickly replacing the MA6 series. The MA7 Series used the 7.62x51mm NATO round in various advanced and exotic forms, guaranteeing its lethality even against shielded and armoured foes. While the round's comparatively low stopping power somewhat limited its effectiveness against Covenant infantry its accuracy and rate of fire, combined with negligible recoil, made it well suited for use in an assault rifle family."@en . . .
