I can guarantee the future will hold nothing but AR18 style rifles, with AR15 features, with the focus being on new intermediate and full power cartridge chamberings and optics. Ar15s/M4s won't be seen in much use by modern militaries with any kind of money or production. I can also guarantee we'll see M4s/AR15s/M16s/whateveryoufagswantocallit being used until firearms themselves are obsolete. They're perfect at being OK rifles. I don't know why everyone gets all crybaby piss pants over the attempts to phase out the AR15s. I would think you dipshits would welcome new platforms being introduced and tested, but then you can't shitpost your faggy opinion on the rifle if something better comes along I guess.
Anyway, show me on the doll where the M4/M7 touched you.
