A lightweight, modular service rifle with matte black steel and cracked polymer grip, bearing faint scorch marks of electroplasmic interference. Familiar to any Marine, its optics and suppressor attachments hum faintly with residual aether flux.

A lightweight, gas-operated, magazine-fed M4 Carbine chambered in 5.56×45mm NATO. The rifle is constructed from aluminum alloys, steel, and reinforced polymers, making it both durable and relatively lightweight. It is highly modular, featuring a full-length Picatinny rail system that allows modern accessories to be mounted as mission requirements change. This rifle is equipped with a holographic sight, visible aiming laser, tactical weapon light, sound suppressor, vertical foregrip, and thirty-round detachable box magazines. The suppressor reduces muzzle flash and sound but does not make the weapon silent. The weapon is capable of both semi-automatic precision fire and fully automatic suppressive fire. In trained hands it is effective out to approximately 500–600 meters. To the people of this world, the M4 appears less like a weapon and more like an artifact from an impossible civilization. Its deafening report, incredible accuracy, rapid rate of fire, and unfamiliar construction often lead observers to mistake it for an enchanted relic or divine instrument rather than manufactured technology.

The M4 Carbine originated on Earth and was brought into this world by the Earth Survivors during the catastrophic event that transported them across realities. It is not magical, divine, or forged by any known civilization. Every surviving rifle is an irreplaceable relic of another world, and replacement parts, ammunition, and accessories are extremely limited.
