Third Generation Battle Rifle

Polymer cased ammo? Caselesss ammo (HK G11 type)? Coil/rail weapons? Energy? Who knows. I'm not smart enough to figure it out. I just know that modern ammo components (metallic cartridge, smokeless powder, Boxer/Berden primers, copper jacketing, pointed spitzer bullet) are technology that is over 120 years old. Manufacturing has improved, as well as our ability to fine tune shapes, sizes and weights, but modern ammo has remained essentially unchanged since the end of the 19th century.
